Vaccines have contributed to a significant reduction in many childhood infectious diseases, such as diphtheria, measles, and Haemophilus influenzae type b (Hib). As an example, because of effective vaccines, wild poliovirus, which causes polio, one of the most feared diseases, has been eliminated in the United States. With high vaccination rates, it is now rare for children in the United States to experience the devastating and often deadly effects of some infectious diseases that were once common in the United States and other countries.

Vaccines to prevent infectious diseases are given to millions of babies, children, adolescents and adults and it is critical that they are demonstrated to be safe and effective. Ensuring the safety and effectiveness of vaccines is one of the Food and Drug Administration's (FDA) top priorities. The Center for Biologics Evaluation and Research (CBER) is the center within FDA that has regulatory oversight of vaccines in the United States assuring their safety and effectiveness.

Because immunization programs of the 20th and 21st century have been so successful, many of today’s parents have never seen many vaccine-preventable diseases and do not understand the potential for them to re-emerge. If too many individuals choose not to vaccinate themselves or their children, some diseases that are now rare or non-existent in this country may resurface.

The viruses and bacteria that cause vaccine-preventable diseases and death still exist and can cause disease in people who are not protected by vaccines. For example, although measles has not been constantly present in the United States since 2000 and was declared eliminated in the U.S. that year, cases and outbreaks continue to occur. This is attributed to various factors, including the common occurrence of measles in many parts of the world, unvaccinated travelers with measles who are bringing the disease into the United States from other countries, and the spread of measles in communities in the U.S. where groups of people are unvaccinated. In 2019, there were more than 1,200 confirmed cases of measles in 31 states and that year marked the greatest number of reported measles cases in the U.S. since 1992 and since measles was declared eliminated in 2000. Of those diagnosed with measles, approximately 10% required hospitalization. The majority of the cases were among people who were not vaccinated against measles.

Outbreaks of measles continue to occur each year. Measles is one of the most contagious diseases and can cause severe complications, including pneumonia, swelling of the brain, and death. Outbreaks of infectious diseases, such as measles, serve as a reminder that they are only a plane-ride away and the best way not to get sick is to get vaccinated.

Benefits and Risks

A vaccine is a medication. Like any medicine, vaccines have benefits and risks, and although highly effective, no vaccine is 100 percent effective in preventing disease or 100 percent safe in all individuals. Most side effects of vaccines are usually minor and short-lived. For example, a person may feel soreness at the injection site or experience a mild fever. Serious vaccine reactions are extremely rare, but they can happen.

"Parents should know that the risk of being harmed by a vaccine is significantly smaller than the risk of serious illness from infectious diseases," says David Kaslow, M.D., director of the Office of Vaccines Research and Review in CBER. "Vaccination is a very important step to get children off to a healthy start."

The vaccine development process and FDA’s evaluation are rigorous and comprehensive, and vaccines are closely monitored after FDA-approval using various surveillance systems to identify uncommon adverse reactions or long-term complications that may occur.

For more information on potential adverse reactions, talk with your healthcare provider, and some vaccines also have FDA-approved labeling specifically for the vaccine recipient that can be a resource of information. It is important to discuss with your healthcare provider any prior reactions to vaccines and any adverse reactions following vaccination.

Types of Routinely Administered Vaccines for Children

How vaccines work

Vaccines work by mimicking the infectious organism (bacteria or viruses) that cause disease. They prepare the body’s immune system for future exposure to disease-causing viruses or bacteria. The parts of the infectious organism that the immune system recognizes are foreign to the body and are called antigens. Vaccination exposes the body to these antigens. Vaccines may contain weakened bacteria or viruses, or parts of bacteria or viruses, or the genetic information for a specific protein that instructs the body to produce a small amount of that protein. As a result of vaccination, the body’s immune system recognizes the antigens from the vaccine are foreign and shouldn’t be in the body, but the antigens don’t cause disease in the person receiving the vaccine. After receiving the vaccine, if the virus or bacteria that cause the disease then enters the body in the future, the immune system is prepared and responds quickly and forcefully to attack the disease-causing agent to prevent the person from getting sick with the disease. Vaccines are frequently given by injection (a shot), but some are given by mouth, and one is sprayed into the nose.

There are various types of vaccines that are routinely given to children

• Attenuated (weakened) live viruses - These vaccines contain a live virus that has been weakened during the manufacturing process so that they do not cause the actual disease in the person being vaccinated. However, because they contain a small amount of the weakened live virus, people with weakened immune systems should talk to their healthcare provider before receiving them. Examples include vaccines that prevent chickenpox and rotavirus and measles, mumps and rubella (German measles).
• Inactivated (killed) viruses - These vaccines contain a virus that has been killed so as not to cause disease, but the body still recognizes it and stimulates production of antibodies against the virus. They can be given to individuals with weakened immune systems. Examples include vaccines to prevent polio and hepatitis A.
• Subunits - In some cases, the entire virus or bacteria is not required for an immune response to prevent disease; just the important parts, a portion or a "subunit" of the disease-causing bacteria or virus is needed to provide protection. Some vaccines for the prevention of influenza (the flu) that are given as an injection is an example of a subunit vaccine, because it is made with parts of the influenza virus.
• Toxoids - Some bacteria cause illness in people by secreting a poison (a toxin). Scientists discovered that weakening the toxins, so that they are “detoxified” does not cause illness. Examples of vaccines that contain toxoids include those to prevent tetanus and diphtheria disease.
• Recombinant - These vaccines are made by genetic engineering, the process and method of manipulating the genetic material of an organism. The vaccine that prevents certain diseases caused by the human papillomavirus (HPV), such as cervical cancer, is an example of this type of vaccine. In this case, the genes that code for a specific protein from each of the virus types of HPV included in the vaccine are expressed in yeast to create large quantities of the protein. The protein that is produced is purified and then used to make the vaccine. Because the vaccine only contains a protein, and not the entire virus, the vaccine cannot cause the HPV infection. It is the body's immune response to the recombinant protein(s) that then protects against diseases caused by the naturally occurring virus.
• Polysaccharides - To protect against certain disease-causing bacteria, the main antigens in vaccine are sugar-like substances called polysaccharides; these are purified from the bacteria to make polysaccharide vaccines. However, vaccines composed solely of purified polysaccharides are only effective in older children and adults. Pneumovax 23, a vaccine for the prevention of pneumococcal disease caused by 23 different strains, is an example of a polysaccharide vaccine.
• Conjugates - Vaccines made only with polysaccharides do not work very well in young children because their immune system has not fully developed. To make vaccines that protect young children against diseases caused by certain bacteria, the polysaccharides are connected to a protein so that the immune system can recognize and respond to the polysaccharide. The protein acts as a “carrier” for the part of the vaccine that will stimulate the immune system to make protective antibodies in the body. Examples of conjugate vaccines include those to prevent invasive disease caused by Haemophilus influenzae type b (Hib).
• Messenger RNA (mRNA) - mRNA is found naturally in the body and carries genetic information needed to make proteins. Similarly, the mRNA in mRNA vaccines also provide instructions to cells in the body to make proteins. For example, certain vaccines that prevent COVID-19 contain a synthetic piece of mRNA that instructs cells in the body to make the distinctive "spike" protein of the SARS-CoV-2 virus. When vaccinated, the body produces copies of the spike protein, which does not cause disease, and the immune system learns to react defensively, producing an immune response against SARS-CoV-2 when the body encounters it. Examples of mRNA vaccines include the following for the prevention of COVID-19: Comirnaty, Moderna COVID-19 Vaccine, Pfizer-BioNTech COVID-19 Vaccine and Spikevax.

Steps to Take When Your Child is Vaccinated

Review the vaccine information statements

These sheets are produced by the Centers for Disease Control and Prevention (CDC) and explain both the benefits and risks of a vaccine. Healthcare providers are required by law to provide them.

Talk to your healthcare provider about the benefits and risks of vaccines

Learn the facts about the benefits and risks of vaccines, along with the potential consequences of not vaccinating against diseases. Some parents and caregivers are surprised to learn that children can be harmed or die of measles, diphtheria, pertussis (whooping cough), and other vaccine-preventable diseases.

Conditions to make your healthcare provider aware of before vaccination

This might include being sick or having a history of certain allergic or other adverse reactions to previous vaccinations or their components. For example, eggs are used to grow many influenza (flu) vaccines; therefore, it is important to inform the healthcare provider if a child is severely allergic to eggs.

The packaging of some vaccines that are supplied in vials or prefilled syringes may contain natural rubber latex, which may cause allergic reactions in latex-sensitive individuals; therefore, an allergy to latex is helpful to inform healthcare providers of beforehand.

It is also particularly important to discuss with your healthcare provider which vaccines should or should not be given to those children who have weakened immune systems.

Report adverse reactions

Adverse reactions and other problems related to vaccines should be reported to the Vaccine Adverse Event Reporting System, which is maintained by FDA and CDC. For a copy of the vaccine reporting form, call 1-800-822-7967, or report online to www.vaers.hhs.gov

Routinely Administered Vaccines for Children

Some of the most commonly administered vaccines are briefly discussed below. A complete list of vaccines approved by FDA for use in the United States and additional information, such as prescribing information and information for the vaccine recipient are available at: https://www.fda.gov/vaccines-blood-biologics/vaccines/vaccines-licensed-use-united-states.

COVID-19 Vaccine

• Brand Names: Comirnaty and Spikevax are FDA-approved for use in individuals 12 years of age and older.  Children 6 months through 11 years of age may receive either Moderna COVID-19 Vaccine or Pfizer-BioNTech COVID-19 Vaccine, and individuals 12 years of age and older may receive Novavax COVID-19 Vaccine, Adjuvanted.  FDA has authorized Moderna COVID-19 Vaccine, Novavax COVID-19 Vaccine, Adjuvanted and Pfizer-BioNTech COVID-19 Vaccine for emergency use.
• What it’s for: Prevents coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Getting a COVID-19 vaccine is the best way to prevent COVID-19, including the potential consequences of hospitalization and death. In general, COVID-19 tends to be less severe in children than adults, but many children have been hospitalized for COVID-19. Children, like adults, may also experience long-term effects of COVID-19, even following initially mild disease.
• Common side effects may include: Pain, redness and swelling at the injection site, fatigue, headache, chills, fever, swelling under the arm, and pain in the muscles and/or joints. Younger children may also experience irritability/crying, loss of appetite, nausea/vomiting.
• Tell your healthcare provider beforehand if: The child has had myocarditis (inflammation of the heart muscle) or pericarditis (inflammation of the lining outside the heart), is immunocompromised or is on a medicine that affects the child’s immune system, has received another COVID-19 vaccine, or has any of the following: a fever, any allergies, a bleeding disorder or is on a blood thinner or has ever fainted in association with an injection.

Diphtheria and Tetanus Toxoids and Acellular Pertussis Adsorbed (DTaP) Vaccine

• Brand Names:  Daptacel and Infanrix
• What it's for: Prevents the bacterial diseases diphtheria, tetanus (lockjaw), and pertussis (whooping cough). This combination vaccine is given as a series in infants and children 6 weeks through 6 years of age, prior to their 7th birthday. The bacteria that cause diphtheria can infect the throat, causing a thick covering that can lead to problems with breathing, paralysis, or heart failure. Tetanus can cause painful tightening (spasms) of the muscles, seizures, paralysis, and death. Pertussis, also known as whooping cough, has the initial symptoms of runny nose, sneezing, and a mild cough, which may seem like a typical cold.  Usually, the cough slowly becomes more severe.  Eventually the patient may experience bouts of rapid coughing followed by the “whooping” sound that gives the disease its common name as they try to inhale. While the coughing fit is occurring, the patient may vomit or turn blue from lack of air. Patients gradually recover over weeks to months.
• Common side effects may include: Fever, drowsiness, fussiness/irritability, and redness, soreness, or swelling at the injection site.
• Tell your healthcare provider beforehand if: The child is moderately or severely ill, has had swelling of the brain within 7 days after a previous dose of vaccine, has a neurologic disorder such as epilepsy, or has had a severe allergic reaction to a previous dose.

Tetanus Toxoid, Reduced Diphtheria Toxoid and Acellular Pertussis Vaccine Adsorbed (Tdap) Vaccine

• Brand Names: Adacel and Boostrix
• What it's for: Booster vaccination for kids at 10 or 11 years of age to prevent the bacterial infections diphtheria, tetanus (lockjaw), and pertussis (whooping cough). In addition, Boostrix is approved for all individuals 10 years of age and older, (including the elderly). Adacel is approved for use in people ages 10 through 64 years. Both vaccines are also approved for use during the third trimester of pregnancy to prevent pertussis (whooping cough) in infants younger than 2 months of age. 
• Common side effects may include: Pain, redness and swelling at the injection site, headache, and tiredness.
• Tell your healthcare provider beforehand if: The child is moderately or severely ill, has had swelling of the brain within 7 days after a previous dose of pertussis vaccine, or any allergic reaction to any vaccine that protects against diphtheria, tetanus or pertussis diseases.

Haemophilus b Conjugate Vaccine (Hib) Vaccine

• Brand Names:  ActHIB, Hiberix, and PedvaxHIB
• What it's for:  Prevents Haemophilus influenzae type b (Hib) invasive disease. Before the availability of Hib vaccines, Hib disease was the leading cause of bacterial meningitis among children under 5 years of age in the United States. Meningitis is an infection of the tissue covering the brain and spinal cord, which can lead to lasting brain damage and deafness. Hib disease can also cause pneumonia, severe swelling in the throat, infections of the blood, joints, bones, and tissue covering of the heart, as well as death. Both ActHIB and PedvaxHIB are approved for infants and children beginning at 2 months; ActHIB can be given through 5 years of age and PedvaxHIB can be given through 71 months of age. Hiberix is approved for infants and children 6 weeks through the age of 4 years (prior to their 5th birthday).
• Common side effects may include: Fussiness, sleepiness, and soreness, swelling and redness at the injection site.
• Tell your healthcare provider beforehand if: The child is moderately or severely ill, or has ever had an allergic reaction to a previous dose of Hib vaccine.

Hepatitis A Vaccine

• Brand Names: Havrix and Vaqta
• What it's for: Prevents disease caused by hepatitis A virus. People infected with hepatitis A may not have any symptoms; and if they do have symptoms, they may feel like that they have a mild "flu-like" illness; or they may have jaundice (yellow skin or eyes), tiredness, stomachache, nausea and diarrhea. Young children may not have any symptoms, so when a child’s caregiver becomes sick, that is when it is recognized that the child is infected. Hepatitis A is most often spread by an object contaminated with the feces of a person with hepatitis A, such as when a parent or caregiver does not properly wash his or her hands after changing diapers or cleaning up the stool of an infected person. Both vaccines are approved for use in people 12 months of age and older. 
• Common side effects may include: Soreness and redness at the injection site, and loss of appetite.
• Tell your healthcare provider beforehand if: The child is moderately to severely ill, or has ever had an allergic reaction to a previous dose of the vaccine.

Hepatitis B Vaccine

• Brand Names (for children): Engerix-B and Recombivax HB
• What it's for: Prevents infection caused by hepatitis B virus. Hepatitis B is spread when body fluid infected with hepatitis B enters the body of a person who is not infected. This can happen through an infected individual passing it to their baby at birth, sex with an infected person, or direct contact with an infected person where blood is passed through breaks in the skin. Hepatitis B can lead to chronic hepatitis (liver inflammation), liver cancer, and death. The vaccines are approved for individuals of all ages, including newborns.
• Common side effects may include: Soreness, redness, swelling at injection site, irritability, fever, diarrhea, fatigue/weakness, loss of appetite and headache.
• Tell your healthcare provider beforehand if: The child is moderately or severely ill, or has ever had a life-threatening allergic reaction to yeast or to a previous dose of the vaccine.

Human Papillomavirus Vaccine

• Brand Names: Gardasil 9
• What it's for: Gardasil 9 is for use in females and males ages 9 through 45 years. It prevents cervical, vulvar, vaginal, anal, and certain head and neck cancers caused by any of the following human papillomavirus (HPV) Types 16, 18, 31, 33, 45, 52 and 58. Overall, Gardasil 9 has the potential to prevent approximately 90% of cervical, vulvar, vaginal and anal cancers. Gardasil 9 is also approved for the prevention of genital warts caused by types 6 and 11 in both males and females.
• Common side effects may include: Headache, fever, nausea, dizziness, fainting, and pain, swelling, redness, itchiness or bruising at the injection site.
• Tell your healthcare provider beforehand if: The individual has had an allergic reaction to yeast or to a previous dose of the vaccine.  

Influenza Vaccine (administered with a needle)

• Brand Names (for children): Afluria, Fluarix, Flucelvax, FluLaval, and Fluzone
• What it's for:  Prevents influenza disease caused by the strains of influenza virus that are included in the vaccine.  
  Influenza, commonly called “flu,” is a contagious respiratory virus that can cause mild to severe illness. The elderly, young children and people with certain health conditions (such as asthma, diabetes, or heart disease) are at high risk for serious influenza-related complications. Complications may include pneumonia, ear infections, sinus infections, dehydration, and worsening of certain medical conditions such as congestive heart failure, asthma or diabetes.
  The strains of influenza virus that cause disease in people frequently change, so yearly vaccination is needed to provide protection against the influenza viruses likely to cause illness each flu season.
• Common side effects may include: Pain, redness and swelling at the injection site, low grade fever, and muscle aches, headache, fatigue and general feeling of being unwell.
• Tell your healthcare provider beforehand if: The child is moderately or severely ill, has immune system problems, or has had Guillain-Barre Syndrome (GBS), a neurological disorder that causes severe muscle weakness. Also, tell your healthcare provider about any allergies, including severe allergies to eggs and any allergic reaction to a previous dose of any influenza vaccine.

Influenza Vaccine, Intranasal (nasal spray)

• Brand Name: FluMist
• What it's for: Protects against different strains of influenza virus included in the vaccine; for children and adults ages 2 through 49 years of age.  
• Common side effects may include: Runny or stuffy nose and cough.
• Tell your healthcare provider beforehand if: The child is moderately or severely ill, has a weakened immune system, has asthma or a history of or current wheezing, is taking antiviral drugs for treatment of influenza, or has a history of Guillain-Barre Syndrome (GBS), a neurological disorder that causes severe muscle weakness. Also, tell your healthcare provider about any allergies, including severe allergies to eggs and any allergic reaction to a previous dose of any influenza vaccine. In addition, because of the association of Reye's syndrome with aspirin and wild-type influenza infection, the healthcare provider should be made aware if the child is currently receiving aspirin or aspirin-containing therapy.

Measles, Mumps and Rubella Vaccine

• Brand Names: M-M-R II and Priorix
• What it's for: Prevents measles, mumps, and rubella in those 12 months of age and older. Measles is a respiratory disease that causes a skin rash all over the body, and fever, cough and runny nose.  Measles can be severe, causing ear infections, pneumonia, seizures, and swelling of the brain. Mumps causes fever, headache, loss of appetite and the well-known sign of swollen cheeks and jaw which is from the swelling of the salivary glands. Rare complications include deafness, meningitis (infection of the lining that surrounds the brain and spinal cord), and painful swelling of the testicles or ovaries. Rubella, also called German Measles, causes fever, a rash, and--mainly in women--can also cause arthritis. Rubella infection during pregnancy can lead to birth defects.
• Common side effects may include: Fever, mild rash, fainting, headache, dizziness, irritability and burning/stinging, redness, swelling, and tenderness at the injection site.
• Tell your healthcare provider beforehand if: The child is ill and has a fever or has ever had an allergic reaction to gelatin, the antibiotic neomycin, or a previous dose of the vaccine, has immune system problems, or cancer, or problems with the blood or lymph system.

Meningococcal Vaccine

There are different types of bacterial meningococcal vaccines approved by the FDA. One type protects against disease caused by four groups of meningococcal bacteria: A, C, W-135, and Y. Another type protects against disease caused by the following five groups: A, B, C, W and Y. Another type protects against disease caused by group B. 

• Brand Names: Bexsero, MenQuadfi, Menveo, Penbraya, and Trumenba
• What it's for: Prevents certain types of meningococcal disease, a life-threatening illness caused by the bacteria Neisseria meningitidis (N. meningitidis) that infects the bloodstream and the lining that surrounds the brain and spinal cord (meningitis). Neisseria meningitidis is a leading cause of meningitis in young children. Even with appropriate antibiotics and intensive care, between 10 and 15 percent of people who develop meningococcal disease die from it. Another 10 to 20 percent suffer complications such as brain damage or loss of limb or hearing. Bexsero and Trumenba are approved for use in those 10 through 25 years of age to prevent invasive meningococcal disease caused by N. meningitidis group B. MenQuadfi and Menveo prevent meningococcal disease caused by N. meningitidis groups A, C, Y and W-135. Menveo is approved for use in those 2 months through 55 years of age.  MenQuadfi is approved for use in those 2 years of age and older. Penbraya prevents invasive disease caused by N. meningitidis groups A, B, C, W, and Y and is approved for use in individuals 10 through 25 years of age.
• Common side effects may include: Tenderness, pain, redness and swelling at the injection site, irritability, headache, fever, tiredness, chills, diarrhea and loss of appetite for a short while.
• Tell your healthcare provider beforehand if: The child is moderately or severely ill, has had a severe allergic reaction to a previous dose of meningococcal vaccine, or has a known sensitivity to vaccine components.

Pneumococcal Conjugate Vaccine

Streptococcus pneumoniae (S. pneumoniae), also known as pneumococcus are bacteria that can infect the lungs or ears, but when it infects the blood (bacteremia) or the coverings of the brain or spinal cord (meningitis) it is called invasive pneumococcal disease. It can be a very serious disease. Young children are an age group at increased risk. FDA has approved vaccines to prevent disease caused by different types of S. pneumoniae.

• Brand Names (for children): Prevnar 20 and Vaxneuvance
• What it's for: Prevnar 20 prevents invasive disease caused by 20 different types of the bacterium S. pneumoniae covered by the vaccine in individuals 6 weeks of age and older. For infants and children 6 weeks through 5 years of age, it is also approved for the prevention of otitis media (ear infection) caused by 7 different types of the bacterium covered by the vaccine. Vaxneuvance prevents invasive disease caused by 15 different types of the bacterium S. pneumoniae covered by the vaccine in individuals 6 weeks of age and older.
• Common side effects may include: Pain, redness and swelling at the injection site, irritability, drowsiness, headache, decreased appetite and fever.
• Tell your healthcare provider beforehand if: The child is moderately or severely ill, has ever had an allergic reaction to a previous dose or component of the vaccine, including diphtheria toxoid (for example, DTaP vaccine).

Poliovirus Vaccine

• Brand Name: Ipol
• What it's for: Prevents polio in individuals 6 weeks of age and older. Polio is a disease that can cause paralysis or death. 
• Common side effects may include: Redness, hardening and pain at the injection site, fever, irritability, sleepiness, fussiness, and crying.
• Tell your healthcare provider beforehand if: The child is moderately or severely ill, including illness with a fever, has ever had a severe allergic reaction to a previous dose of polio vaccine, any component of the vaccine, or an allergic reaction to the antibiotics neomycin, streptomycin, or polymyxin B.

Rotavirus Vaccine

• Brand Names: Rotarix and RotaTeq
• What it's for: Prevents gastroenteritis caused by rotavirus infection in infants 6 to 32 weeks of age for RotaTeq and 6 to 24 weeks of age for Rotarix. Rotavirus disease is the leading cause of severe diarrhea and dehydration in infants worldwide. In the United States, the disease occurs more often during the winter. Before rotavirus vaccines were available, most children in the United States were infected with rotavirus before the age of two. In addition, rotavirus resulted in about 55,000-70,000 hospitalizations and 20-60 infant deaths in the United States each year.
• Common side effects may include: Fussiness/irritability, cough/runny nose, fever, and loss of appetite.
• Tell your healthcare provider beforehand if: The child has illness with a fever, a weakened immune system because of a disease, has a blood disorder, any type of cancer, has gastrointestinal problems, has had stomach surgery or ever had intussusception, which is a form of blockage of the intestines, is allergic to any of the ingredients of the vaccine, or has ever had an allergic reaction to a previous dose of the vaccine, or has regular close contact with a member of a family or household who has a weak immune system.

Varicella Virus Vaccine

• Brand Name: Varivax
• What it's for: Prevents varicella (chickenpox) in children 12 months of age and older. Chickenpox usually causes a blister-like itchy rash, tiredness, headache and fever. It can be serious, particularly in babies, adolescents, adults and people with weak immune systems, causing less common, but more serious complications such as skin infection, scarring, pneumonia, brain swelling, Reye's syndrome (which affects the liver and brain), and death.
• Common side effects may include: Soreness, pain, redness or swelling at the injection site, fever, irritability, and chicken-pox like rash on the body or at the site of the injection.
• Tell your healthcare provider beforehand if: The child is moderately or severely ill, including a fever, has a weak immune system, has received a blood or plasma transfusion or immune globulin within the last 5 months, takes any medicines, has allergies including any life-threatening allergic reaction to gelatin, the antibiotic neomycin, or a previous dose of chickenpox or any other vaccine.

Parents and Caregivers are Asking

Should I be worried about the increasing number of vaccines administered to children?

No. Vaccines represent only a minor stimulation of the infant immune system compared to the large number of potentially dangerous bacteria and viruses babies routinely encounter: starting immediately after a baby is born; thousands of different bacteria begin to live on the skin and the lining of the nose, throat, and intestines. The baby’s immune system rapidly launches immune responses to these bacteria that prevent them from invading the blood stream.

Are the ingredients in vaccines safe?

Yes. Each ingredient in a vaccine is included for a reason. Before FDA determines that a vaccine is safe and effective and approves it for use in the United States, the vaccine is thoroughly evaluated by FDA scientists and doctors, taking into account the ingredients that make up the entire vaccine.

Are vaccines linked to autism?

No, the scientific evidence does not support a link between vaccination and autism or other developmental disorders.
