Is it necessary to get the 9-valent vaccine?

Generally speaking, the term "nine-valent" refers to the nine-valent HPV vaccine, which is recommended for vaccination. The detailed explanation is as follows:

HPV is the primary causative agent of cervical cancer and various other genital cancers. The nine-valent HPV vaccine covers multiple high-risk HPV strains, including HPV-16, 18, 31, 33, 45, 52, and 58. These viral types are associated with cervical cancer and a significant proportion of genital warts and other lesions. Receiving the nine-valent HPV vaccine significantly reduces the risk of developing these diseases. The preventive effect is particularly effective when the vaccine is administered during adolescence, before becoming sexually active.

Adults who have already had sexual experiences can still benefit from the nine-valent HPV vaccine, as it can prevent infection from HPV types they have not yet encountered. Additionally, through cross-protection, it may provide some immune protection against HPV types they have already been infected with but have not yet caused lesions. Furthermore, the nine-valent HPV vaccine has undergone rigorous clinical trials and regulatory approval processes and has been proven safe and effective. Its adverse reactions are usually mild, such as pain, redness, swelling at the injection site, or fever, and most symptoms resolve on their own within a short period.

In daily life, it is important to practice safe sexual behaviors, maintain personal hygiene, follow a balanced diet rich in fresh vegetables and fruits, ensure adequate sleep, and engage in appropriate physical exercise to enhance overall immunity.
