The 4-valent cervical cancer vaccine is suitable for people aged 20-45, and the injection effect is not good beyond this age group; the nine-valent vaccine is suitable for patients aged 16-26, preferably injected before no sexual life, so as to achieve the best effect of the vaccine; cervical screening should be done before vaccine injection, and cervical lesions can be diagnosed through cervical TCT and HPV examination.
