NIH study finds two doses of HPV vaccine may be as protective as full course – 3
Narrator: This is NIH Health Matters. I’m Joe Balintfy. A clinical trial in Costa Rica has researchers suggesting that giving an HPV vaccine to more women, with fewer doses for each, could reduce cervical cancer incidence more than a standard three-dose program for fewer women. Dr. Aimée Kreimer at the NIH explains results after four years of follow-up.
Kreimer: What we observed was that the vaccine efficacy for women who received two doses or even a single dose was quite comparable to that of the standard regimen.
Narrator: She says further studies are needed to confirm the findings in other populations and to calculate how long protection lasts with fewer doses. For more information, visit www.cancer.gov.
