Is it necessary for a 40-year-old to get the 9-valent vaccine?
The 9-valent vaccine refers to the 9-valent human papillomavirus (HPV) vaccine. For women aged 40 who have not previously received any HPV vaccine, it is necessary to receive the 9-valent HPV vaccine. The analysis is as follows:
For women aged 40, if they have not previously received any HPV vaccine, and have not been infected with HPV or have not completed the full vaccination schedule, the risk of HPV infection still exists. Receiving the 9-valent HPV vaccine can provide additional protection against cervical cancer and other related cancers caused by multiple high-risk types of HPV. Although women aged 40 may have already been exposed to HPV through sexual activity, receiving the 9-valent vaccine can still provide additional protection against high-risk HPV types they have not yet been infected with, or reduce the further risk of HPV infections that are already present but have not yet caused lesions.
Whether to receive the 9-valent HPV vaccine also needs to consider individual health conditions and willingness to be vaccinated. If economic factors or other contraindications exist, women aged 40 may choose not to be vaccinated according to their own preference. After vaccination, it is important to keep the injection site clean and dry, avoiding contact with water.
