Increasing HPV Vaccination Among Young Men Could Help Eliminate Cervical Cancer, Study Suggests
A recent study conducted by researchers at the University of Maryland in the US has highlighted the importance of increasing HPV vaccination rates among young men to help eliminate cervical cancer. The study found that current vaccination programs, which primarily target girls, may not be sufficient to achieve herd immunity against cancer-causing strains of HPV.
The mathematical model developed by the research team indicates that in countries like South Korea, where only girls are vaccinated against HPV, expanding the vaccination program to include boys could have a significant impact on preventing HPV-associated cancers, such as cervical, anal, penile, and oral cancers.
According to senior author Abba Gumel, vaccinating boys not only reduces the burden of achieving high vaccination coverage among females but also makes the elimination of HPV-related cancers more achievable. The simulations conducted by the team suggest that including boys in the HPV vaccination program could potentially lead to the elimination of HPV-related cancers in about 70 years in South Korea.
The study, which was calibrated using cancer data from South Korea, has broader implications for other national vaccination programs. Gumel predicts that achieving approximately 70 percent vaccination coverage among both men and women in countries like the US could help attain herd immunity against HPV.
HPV is a highly contagious virus that can be transmitted through sexual contact or skin-to-skin contact. It is responsible for nearly all cases of cervical cancer, which claims over 300,000 lives globally each year.
While the first HPV vaccine was initially marketed as a preventive measure for women, research has shown that both men and women are at risk of HPV-associated cancers. Despite the effectiveness of the vaccine in reducing cervical cancer cases, there remains a significant gender disparity in vaccination rates.
In countries like South Korea, the study found that achieving herd immunity against cervical cancer would require higher vaccination coverage among females unless boys are also included in the vaccination program. By vaccinating a certain percentage of males alongside existing female vaccination rates, countries could potentially eliminate cervical cancer.
The study underscores the importance of including young boys in HPV vaccination programs to prevent future cases of HPV-related cancers. By expanding vaccination coverage to include both sexes, countries could significantly reduce the burden of HPV-related diseases and work towards the goal of eliminating cervical cancer.
With increasing vaccination rates among boys and girls, researchers believe that it is possible to see an end to HPV and HPV-related cancers in the near future. By improving vaccination coverage and expanding screening programs, countries can take significant steps towards eliminating cervical cancer and saving lives.
The findings of the study were published in the Bulletin of Mathematical Biology.
