Can the bivalent HPV vaccine and the nonavalent HPV vaccine be administered repeatedly?
The bivalent HPV vaccine and the nonavalent HPV vaccine can be administered repeatedly.
The bivalent HPV vaccine helps prevent infections caused by human papillomavirus (HPV) types 16 and 18. It is suitable for females aged 9 to 45 and is typically given in three doses over six months. The nonavalent HPV vaccine protects against cervical cancer caused by HPV infection and can prevent approximately 90% of cervical cancer cases. It is recommended for females aged 9 to 45 and offers protection against HPV types 6, 11, 16, 18, 31, 33, and others. The active components of the bivalent and nonavalent HPV vaccines do not interfere with each other. After completing the bivalent HPV vaccine series, individuals who meet the eligibility criteria may also receive the nonavalent HPV vaccine, although it is preferable to wait at least one year between vaccinations.
After vaccination, patients should take care to protect the injection site, avoid contact with water, and refrain from touching it with hands to prevent potential infection.
