What is Vaxneuvance?

Vaxneuvance is a vaccine to help protect against invasive disease caused by 15 types of pneumococcus (pronounced “noomo-ca-cus”), a kind of bacteria. Invasive disease includes:
- an infection in the blood (bacteremia).
- an infection of the coverings of the brain and spinal cord (meningitis).
Vaxneuvance is for individuals 6 weeks of age and older.
Vaxneuvance will not give you disease caused by pneumococcus.
Vaxneuvance might not protect everyone who gets the vaccine.

Who should not get Vaxneuvance?

Do not get Vaxneuvance if you or your child:

have or had an allergic reaction to any of the ingredients in Vaxneuvance or to diphtheria toxoid. (See the list of ingredients at the end of this information sheet.)

Before receiving Vaxneuvance

Tell your healthcare provider if you or your child:

have or had an allergic reaction to any vaccine.
have a weak immune system (which means your body has a hard time fighting off infections).
take medicines or treatments that might weaken your immune system (like immunosuppressants or steroids).
are pregnant or planning to get pregnant.
are breast-feeding.

How is Vaxneuvance given?

Vaxneuvance is given as an injection into the muscle (usually in your upper arm for adults and the upper arm or thigh for children).

Children need 4 doses of the vaccine:

The first injection is given at 2 months old.
The second injection is given at 4 months old.

If your child did not receive the complete series according to this schedule, your healthcare provider may suggest a catch-up schedule.

Your child may get Vaxneuvance at the same time they get other vaccines.

Adults need one dose of the vaccine.
