In recent years, the cervical cancer vaccine has been introduced to major hospitals in major cities one after another, and the demand has exceeded the supply, but there are also many people who have a wait-and-see attitude. The incidence of cervical cancer is very high, second only to breast cancer. Cervical cancer is most common in women aged >35 years old, with a peak incidence of 45-59 years old and a younger incidence trend in the past decade. Cervical cancer is the only malignant disease among the three major gynecological cancers whose cause is known, so HPV vaccine can effectively prevent cervical cancer. The cervical cancer vaccine is also a vaccine, and the common side effects are similar to the general vaccine, such as local redness, swelling, heat and pain at the injection site, dizziness and nausea after the injection, etc. Generally these symptoms will disappear after a few days, but if they occur for a longer time or show signs of aggravation, or if shock occurs, timely hospital consultation is required. After HPV vaccination in some places in the UK, some people produced occurrence, nausea, vomiting, etc., and some people had dizziness, muscle weakness or even muscle paralysis symptoms, etc., and some others had rash such as allergy and pain at the injection site after the injection. However, in general, the side effects of cervical cancer vaccine only appear in very few individuals, and there is no direct evidence that these symptoms are directly caused by cervical cancer vaccine. After all, cervical cancer vaccine is still a newly developed vaccine, and its subsequent effects are not clear, and its side effects on human body remain to be observed. In order to avoid adverse reactions, special periods such as allergies, having immune system diseases, fever and pregnancy are not suitable for cervical cancer vaccination.
