Polio Vaccination in the U.S.
- For best protection, children should get four doses of polio vaccine.
- This vaccine is given as a shot in the arm or leg and is very safe.
Ideally, your child should receive a dose at ages:
- 2 months
- 4 months
- 6 through 18 months
- Booster dose at age 4 through 6 years
Inactivated polio vaccine (IPV) may sometimes be given in the same shot with other vaccines (in other words, in a combination vaccine), so discuss this option with your child’s doctor. Getting the recommended doses of polio vaccine is an important part of keeping the United States polio-free.
For information about adults who may not have received sufficient vaccine protection, see the adult polio vaccination schedule.
- Parents, work with your child’s healthcare provider on doses and timing. If you don’t have health insurance, or if your insurance doesn’t cover vaccines for your child, the Vaccines for Children Program may be able to help.
- Adults, see Finding and Paying for Vaccines or Find a Travel Medicine Clinic
