Is the HPV Vaccine Safe? Can the Vaccine Make HPV Infection Worse?
The study showed an increase in pre-cancer related to the vaccine types in the people who already had these infections before they got the vaccine. It is possible that when infected girls whose immune systems have not cleared the virus from their bodies are vaccinated, the vaccine may lead to an increased number of cases of a pre-cancer. This is very concerning because there is no routine test you can get in your doctor’s office that will tell if you are already infected by a vaccine type HPV before you get the vaccine.
