According to the statistics of the vaccine adverse event reporting system, more than 60 million doses of HPV vaccine have been used at present, and there is no data showing that there have been serious adverse reactions after vaccination. So in general, the cervical cancer vaccine is safe and can be used.

However, some people may have symptoms similar to colds after vaccination, such as headache and dizziness, and some injection sites may have pain and redness, which is only the reason for personal physical differences. If there is redness after vaccination, you can try to apply raw potato chips to the redness or hot compress to promote swelling.

2 Do you need to have an examination before getting a cervical cancer vaccine? 1. Generally speaking, women who have never had sex do not need special examination before vaccination.

2. Women who have had sex need to do cervical cancer washing test (currently recommended TCT) and human papillomavirus DNA test. If cervical lesions or human papillomavirus infection are found in the examination, it is recommended not to take cervical cancer vaccine for the time being, because it will have a certain impact on the effectiveness of the vaccine.

What should I do? If you have cervical lesions, you need to be treated first, and then you should be injected with cervical cancer vaccine after your condition improves.

If you have human papillomavirus infection, such as HPV 16 and HPV 18, you can postpone the vaccination plan for one year, because in general, the virus will subside after 9 months.

3 Classification of Cervical Cancer Vaccines At present, there are three kinds of HPV vaccines on the market, namely bivalent, tetravalent and nonavalent.

Bivalent bivalent cervical cancer vaccine is produced by GlaxoSmithKline, which mainly targets at 16 and 18 human papillomavirus, and can prevent about 70% of cervical cancer, so it is called cervical cancer vaccine.

Tetravalent tetravalent cervical cancer vaccine is produced by Merck. In addition to effectively preventing cervical cancer caused by human papillomavirus 16 and 18, it can also prevent two low-risk subtypes 6 and 1 1 that can cause condyloma acuminatum. At present, Sifang has been listed in some cities in China, such as Shanghai and Changsha.

Nine-valent nine-valent cervical cancer vaccine is produced by Merck. Based on the original tetravalent vaccine, the vaccine has five subtypes of 3 1, 33, 45, 52 and 58, which can prevent cervical cancer, condyloma acuminatum, vaginal cancer, anal cancer and other genital tumors. At present, the domestic listing time is unknown.

4 The best vaccination time of cervical cancer vaccine The recommended age of bivalent HPV vaccine in China is 9-25 years old. Tetravalent HPV vaccine is suitable for people aged 20-45.

It is suggested that adolescent women in China should be vaccinated between 1 1 years old and 12 years old. For people over 45, vaccination is of little significance.
