Vaccinations are safe and effective for children to receive at the recommended ages.

CDC recommends COVID-19 vaccination for everyone aged 6 months and older. If your child has not gotten vaccinated yet, talk to his or her doctor about getting it as soon as possible.

Vaccines your baby should get

As your child enters their toddler stage, they will start becoming aware of themselves and their surroundings. As a parent, make sure you are aware of their next vaccines.

Between 12 and 23 months of age, your baby should receive vaccines to protect them from the following diseases:

Additional protection your baby may need during RSV season

Children 12 to 19 months old who are at increased risk of severe RSV may be recommended to get an RSV immunization to protect them against severe RSV disease as they enter their second RSV season.

Respiratory Syncytial Virus (RSV)

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.

Children 8 through 19 months old who are at increased risk of severe RSV disease and entering their second RSV season (typically fall through spring) should get a one-dose of an RSV immunization to protect them against RSV. This dose should be given shortly before or during the RSV season.

Children 8 through 19 months who are at greatest risk for severe RSV illness include:

  • Children who were born prematurely and have chronic lung disease
  • Children with severe immunocompromise
  • Children with cystic fibrosis who have severe disease
  • American Indian and Alaska Native children

Care for your child after vaccinations

Call 911 if you think your child might be having a severe allergic reaction after leaving the vaccination site.

Give your child extra care and attention

Pay extra attention to your child for a few days. If you see something that concerns you, call your child’s doctor.

  • Read the Vaccine Information Sheet(s) your child’s doctor gave you to learn about side effects your child may experience.
  • Offer breastmilk or formula more often. It is normal for some babies to eat less during the 24 hours after getting vaccines.

Treat mild reactions

Sometimes children have mild reactions from vaccines, such as pain at the injection site or a rash. These reactions, also called side effects, are normal and will soon go away.

  • Use a cool, damp cloth to help reduce redness, soreness, and/or swelling at the injection site.
  • Reduce fever with a cool sponge bath.
  • Ask your child’s doctor if you can give your child a non-aspirin pain reliever.
