Their valence means the number of cervical cancer they can prevent, and the number of human papillomavirus genes is extremely huge. Bivalent means that it can prevent two kinds of human papillomavirus, tetravalent means that it can prevent four kinds of human papillomavirus, and nine valence is the highest at present, which can prevent nine kinds of viruses and probably prevent 92% of cervical cancer.
These human papillomavirus vaccines are imported, developed and produced from abroad, and the bivalent vaccine is developed and produced by GlaxoSmithKline in the UK. The other two are developed and produced by Merck.
The vaccination of these HPV vaccines also has a considerable relationship with age. The bivalent vaccine has the largest age range, and women aged 9-45 can be vaccinated. The bivalent vaccine is between 20 and 45 years old, and the nine-valent vaccine has the smallest age range. At present, only women aged 65438-06-26 are approved for vaccination in China. Although the latest nine-valent HPV vaccine may have the best preventive effect, it has a short time to market.
This vaccine needs to be injected three times, and the bivalent vaccine needs to be injected once in 0, 1 and June respectively; /kloc-vaccinated with tetravalent vaccine once in October, February and June; Jiujia is also inoculated once in 10, February and June. Nine of them are the most expensive, and the domestic price is basically around 3000 RMB. Many people will go to Hong Kong to play. The price in Hong Kong is cheap, about 1200 Hong Kong dollars.
At present, the price of nine is the most expensive and the hottest, but some doctors suggest that the price of two is basically enough. This age range is relatively wide, although only two viruses can be prevented, but these two viruses are more common and other viruses are not common, so for ordinary people and women with average economic conditions, two prices are enough.
Although the vaccine can prevent human papillomavirus, it does not mean that it can be foolproof after vaccination. Even after vaccination, it is still necessary to have regular gynecological examinations.
