A group of researchers at the Cincinnati Children's Hospital Medical Center has been claiming that the prevalence of human papilloma virus (HPV) tends to reduce by a jab not only in those women who have taken the vaccine against it, but in those unvaccinated as well.
The team had carried out two studies to test the effect of vaccine on rates of HPV infection. Comparing both the study findings, the team has reached the conclusion that both vaccinated and unvaccinated groups are benefited.
HPV is of nearly 40 types, which often leads to sexually transmitted infections, told the researchers. Also, nearly 70% of cervical cancer cases are a result of the infection only.
The group of hundreds of young girls and women in their teenage, which had not received the vaccine before a sexual contact was noted to be benefitted a little less though. The report says that the group of women which had had a dose had shown 69% reduction in infection rates as compared to the former that showed a 49% fall.
"Although the study shows evidence of early herd immunity, the results cannot be generalized to imply you shouldn't get vaccinated, it is "still very important”, said lead author Dr. Jessica Kahn.
