Some parents have been worried about the safety of the HPV vaccine. The vaccine protects against human papilloma virus which can cause cervical cancer.
HPV is a very common sexual infection. The Centers for Disease Control is now recommending both girls and boys get vaccinated.
But parental concerns have kept many teens from getting vaccinated. Doctors now say a new study should be reassuring.
Merck funded a new Kaiser Permanente study that looked at nearly 200,000 girls and young women in California who received the full three doses of the vaccine and found its generally safe.
Researchers found two possible minor side effects associated with the shot - fainting the day of the injection and skin infections within two weeks after.
Doctors hope vaccination rates will rise as a result of this study. The CDC says only 35% of girls in the US got the number of recommended doses last year.
