Vaccine Safety Information
Vaccine Safety During Pregnancy
Although there are certain vaccines women should not get during pregnancy, other vaccinations are not only safe during pregnancy but important to protect the health of both babies and moms.

HPV Vaccine Safety
Vaccination against the human papillomavirus (HPV) prevents several types of cancer in both men and women. All 11– to 12- year-old boys and girls should get two doses of the HPV vaccine to protect against cancers caused by HPV infections. The safety of HPV vaccine has been well studied. HPV vaccines went through years of extensive safety testing before being licensed by the FDA, which only licenses a vaccine if it is safe and effective.

Research on Autism Spectrum Disorder from the National Institutes of Health
Thimerosal is a preservative that can prevent growth of germs, like bacteria and fungi in multi-dose vaccine vials.
Thimerosal was taken out of all childhood vaccines that are routinely recommended in the United States in 2001 as a precaution, though data from many studies show no evidence of harm caused by low doses of thimerosal in medical products.
Measles, mumps, and rubella (MMR) vaccines do not and never did contain thimerosal. Varicella (chickenpox), inactivated polio (IPV), and pneumococcal conjugate vaccines have also never contained thimerosal.
Influenza (flu) vaccines are currently available in both thimerosal-containing (for multi-dose vaccine vials) and preservative-free versions.
Research does not show any link between thimerosal in vaccines and autism. Even after thimerosal was removed from almost all childhood vaccines, autism rates continued to increase.

Safety of Aluminum-Containing Vaccines
Aluminum salts have been used as adjuvants, substances that enhance the immune response, for over 70 years in vaccines. Learn more about their safety through the National Network for Immunization Information.
