Immunizations - Childhood Immunizations

Who should get it?

  • All children need four doses—one at age 2 months, one at 4 months, one at 6 months, and one at 12 to 15 months.

Polio(What is a PDF document?)

This shot protects against polio.

Who should get it?

  • Four doses are given to all children—one at age 2 months, one at 4 months, one at 6 to 18 months, and one at 4 to 6 years.

Rotavirus (Rotarix or RotaTeq)(What is a PDF document?)

This immunization protects against rotavirus infection, which causes severe diarrhea.

Who should get it?

  • Three doses of RotaTeq are given to all children—one at age 2 months, one at 4 months, and one at 6 months. If your child gets Rotarix, two doses are given—one at age 2 months and one at 4 months.

This immunization is swallowed rather than given as a shot. Without this vaccine, most children will get infected by the time they are about 5 years old.

Other immunizations

Your child's doctor may suggest other shots if your child is at higher risk than other children for certain health problems. These may include:

Meningococcal conjugate(What is a PDF document?)

This shot protects against a bacteria that causes meningitis and blood infections (sepsis).

Who should get it?

  • Children who have a higher risk than other children for getting and having severe problems from meningitis need at least two shots. This includes children ages 2 months and older who have certain immune system problems, children who have a damaged or missing spleen, and children who live in or will travel to areas of the world where the disease is common.

Children who remain at high risk need routine booster shots starting a few years after their first doses of meningococcal conjugate shots. Ask your doctor if your child has a high risk of getting infections from bacterial meningitis and whether booster shots are needed.

Pneumococcal polysaccharide (PPSV, or Pneumovax 23)(What is a PDF document?)

This shot does not necessarily reduce the risk of getting pneumonia. But it can prevent some of the serious complications of pneumonia, such as blood infections (sepsis).
