Weakened Immune System and Adult Vaccination

Vaccines are especially critical for people with health conditions such as a weakened immune system.

If you have cancer or other immunocompromising conditions, talk with your doctor about:

  • Influenza vaccine each year to protect against seasonal flu
  • Tdap vaccine to protect against tetanus, diphtheria, and whooping cough
  • Pneumococcal vaccine(s) to protect against pneumonia and other serious pneumococcal diseases
  • HPV vaccine to protect against cancers and genital warts caused by human papillomavirus if you are an adult through age 26 years (HPV vaccine is not recommended for everyone older than age 26 years, but some adults age 27 through 45 years who are not already vaccinated may decide to get HPV vaccine after speaking with their doctor about their risk for new HPV infections and the possible benefits of vaccination. HPV vaccination in this age range provides less benefit, as more people have already been exposed to HPV.)
