HPV vaccine wears off quickly in HIV-positive women
from Family Practice News
Women with HIV probably need a booster shot of HPV vaccine within 2 years to maintain efficacy, according to a Canadian study of quadrivalent HPV vaccine in 136 HIV-positive women. Antibody response to the vaccine is strong enough at 2 years to protect about 90 percent of HIV-negative women against HPV. "But in our population, with approximately a year and a half of follow-up, that number decreased to about 63 percent," said lead investigator Erin Moses, R.N., a researcher at the Women's Health Research Institute in Vancouver, B.C.
