Chickenpox (Varicella) - What Increases Your Risk

You are at risk for chickenpox if you have not had chickenpox or the vaccine and you:

  • Live with someone who has chickenpox.
  • Are indoors for more than 1 hour with someone who has chickenpox.
  • Are in the hospital and share a room with someone who later gets chickenpox or are cared for by a staff member who later gets chickenpox.
  • Have a weak immune system.

After you have had chickenpox or the vaccine, you become immune to the virus. It is possible that you may have a slight reaction after reexposure, such as a few spots and a slight fever. But you aren't likely to get chickenpox more than once.

HPV Vaccine for Adults

Human papillomavirus (HPV) is the virus that causes cervical cancer in women and genital warts in men and women. The HPV vaccine effectively prevents infection with the HPV types responsible for most cervical cancers and can also prevent genital warts. HPV vaccination is most effective during childhood or adolescence, but adults can also benefit from the HPV vaccine.
