Introduction

If the recipient was under the recommended upper age limit when receiving the first two doses of the cervical cancer vaccine—45 years for the bivalent vaccine, 45 years for the quadrivalent vaccine, and 26 years for the nonavalent vaccine—and has completed the first two doses according to the prescribed vaccination schedule, then even if the recipient's age exceeds 45 years when receiving the third dose, vaccination can still proceed.

Generally speaking, the third dose of the cervical cancer vaccine can still be administered even if the recipient is over 45 years old. Detailed explanation is as follows:

Cervical cancer vaccine, also known as human papillomavirus (HPV) vaccine, is used to prevent cervical cancer, genital warts, and other related cancers. If the recipient's age has not exceeded the recommended upper age limit for vaccination when receiving the first two doses, specifically up to 45 years old for the bivalent vaccine, 45 years old for the quadrivalent vaccine, and 26 years old for the nonavalent vaccine, and the first two doses have been completed according to the recommended vaccination schedule, it is still acceptable to continue with the third dose even if the recipient has surpassed the age of 45. The vaccine will still provide protective effects. Additionally, for women over 45 years old who are in good health and have no contraindications to vaccination, if the first two doses have already been administered and have generated a good immune response, completing the third dose may still offer certain benefits.

Specific situations may vary depending on individual health conditions and guidelines from local health authorities. If there are any questions or concerns, it is recommended to consult healthcare professionals or local health departments for more accurate advice.

Is the HPV vaccine effective for individuals who are already infected?

The human papillomavirus (HPV) vaccine is effective against HPV types to which an individual has not yet been exposed, but it is not effective against HPV types that an individual has already contracted. If a person is already infected with HPV type 58, the vaccine will not prevent infection from this type; however, it can still prevent infection from other types not yet encountered, such as HPV types 1, 2, 3, 4, and so on. It is important to understand one's infection status before vaccination and to comprehensively assess the necessity of vaccination.
