Is it beneficial for a 43-year-old to receive the 9-valent HPV vaccine?

Generally, receiving the 9-valent HPV vaccine at age 43 can be effective. However, it is usually ineffective if a person has already been infected with HPV. The actual effectiveness varies from individual to individual. A detailed analysis is as follows:

1. Effective

The 9-valent HPV vaccine is primarily used to prevent cervical cancer caused by HPV infection and is suitable for females aged 9 to 45 years. It tends to work best when administered before becoming sexually active. After becoming sexually active, it's recommended to undergo HPV testing prior to vaccination. If no HPV infection is detected, the vaccine can be administered normally. Generally, women within this age range can receive the 9-valent HPV vaccine, which can provide a certain degree of preventive protection.

2. Ineffective

If a woman is already infected with HPV, the 9-valent HPV vaccine is generally ineffective, as the vaccine only prevents infection but does not treat existing infections. It should also be noted that the older a person is, the weaker their immune defense mechanisms may become, resulting in a reduced ability to produce sufficient antibodies.

In daily life, consuming more fresh fruits and vegetables can help boost immunity while providing essential vitamins.
