- Find out which vaccines are recommended for you and your family members based on your ages.
Babies and toddlers
Your baby’s birth is an exciting time. This is also your first opportunity to protect your child from serious diseases with immunizations.
Hepatitis B vaccine
1st dose of 3
Hepatitis B is an infectious and potentially serious disease that can cause liver damage and liver cancer. There is no cure for hepatitis B. Mothers can unknowingly pass the hepatitis B virus to their babies at birth, which is why babies should get their first dose within 24 hours of birth.
Respiratory syncytial virus (RSV) vaccine
1 Dose
RSV is a common cause of severe respiratory illness in infants and young children. Those infected with RSV can have difficulty breathing and eating, and sometimes may need respiratory support or hydration in the hospital. An RSV immunization uses monoclonal antibodies to protect infants and young children from severe RSV disease. This immunization gives your baby's body extra help to fight an RSV infection.
Infants younger than 8 months old during RSV season (typically fall through spring) should get a one-dose RSV immunization to protect them against RSV. This dose should be given shortly before or during the RSV season.
Protect your baby by providing immunity early in life. Starting at 1 to 2 months of age, your baby receives the following vaccines to develop immunity from potentially harmful diseases.
DTaP vaccine
1st dose of 5
A DTaP vaccine is the best protection from three serious diseases: diphtheria, tetanus, and whooping cough (pertussis). All three of these diseases can be deadly for people of any age, and whooping cough is especially dangerous for babies.
Hib vaccine
1st dose of 3 or 4
Hib disease is a serious illness caused by the bacteria Haemophilus influenzae type b (Hib). Babies and children younger than 5 years old are most at risk for Hib disease. It can cause lifelong disability and be deadly. Doctors recommend that your child get three or four doses of the Hib vaccine (depending on the brand).
Hepatitis B vaccine
2nd dose of 3
Hepatitis B is an infectious and potentially serious disease that can cause liver damage and liver cancer. If babies are infected at birth, hepatitis B can be a lifelong, chronic infection. There is no cure for hepatitis B, but the hepatitis B vaccine is the best way to prevent it.
IPV
1st dose of 4
Polio is a disabling and life-threatening disease caused by poliovirus, which can infect the spinal cord and cause paralysis. It most often sickens children younger than 5 years old. Polio was eliminated in the United States with vaccination, and continued use of polio vaccine has kept this country polio-free.
PCV
1st dose of 4
Pneumococcal disease can cause potentially serious and even deadly infections. The pneumococcal conjugate vaccine protects against the bacteria that cause pneumococcal disease.

Note: CDC does not routinely recommend MenB vaccine for all adolescents. Instead, healthcare providers and parents can discuss the risk of the disease and weigh the risks and benefits of vaccination.
MenABCWY vaccine
1 dose
Meningococcal disease can refer to any illness caused by a type of bacteria called Neisseria meningitidis. These bacteria can cause meningococcal meningitis and bloodstream infections, which can be serious, even deadly. Pentavalent meningococcal vaccine, or MenABCWY vaccine, helps protect against five types of the bacteria that causes meningococcal disease (serogroups A, B, C, W, and Y).
