Recommended Immunizations for Babies

In early childhood, vaccines are particularly critical — they help protect babies and young children from a host of life-threatening illnesses when they’re most vulnerable.

New parents can consult the Center for Disease Control and Prevention’s (CDC) vaccination schedule to learn what shots and vaccines are recommended for children through age 18.

Should My Child Be Vaccinated?

Parents who refuse or delay vaccines are placing their children and others in harm’s way. The U.S. Food & Drug Administration (FDA) assures that vaccines given in combination — starting at birth — neither overwhelm nor compromise the child’s immune system.

Most children never experience side effects from getting vaccines. And if they do, they are mild, temporary, and not dangerous. Some children feel tenderness, redness, or swelling at the injection site, but this is rare. The benefit of protecting your child against preventable diseases should outweigh any minor reaction.

The required and life-saving vaccines your child needs are 90% to 99% effective. That’s why it’s important to talk with your pediatrician about an immunization schedule. The American Academy of Pediatrics and the CDC strongly support following the existing guidelines to protect children, family members, and friends.

Know Your Vaccines

The following is an overview of important vaccines and what they protect against:

DTaP: Combines protection against diphtheria, tetanus, and pertussis (whooping cough)

Hepatitis A and B: Exposure to either virus can lead to organ infection or failure, blood disorders, and even cancers

Hib: Protects against Haemophilus influenzae type B, a bacteria that causes life-threatening meningitis in young children

Influenza: Protects against the flu virus, which can lead to pneumonia and even death

IPV: Protects against polio, which can cause disability, paralysis, or death

MMR: Combines protection against measles, mumps, and rubella

PCV: Known as the pneumococcal vaccine, it protects against life-threatening bacterial meningitis and pneumonia

Rotavirus: Protects against rotavirus infections, the leading cause of severe diarrhea in young children

Varicella: Protects against the chickenpox virus, which can cause a mild to life-threatening illness

  • Fourth dose of hepatitis B*

*Note: The CDC requires three doses of hepatitis B immunization, which are typically administered during the first year of a baby’s life. Many pediatricians, however, administer four doses by including the hepatitis B shot as a part of a routine combination vaccine.
