1.Choosing the vaccine At present, there are mainly two kinds of cervical cancer vaccines approved, one is the Gardasil vaccine produced by the U.S. Merck Sharp & Dohme pharmaceutical company for both men and women, and the other is the Huuyin Kang vaccine for women only. The main difference between the two vaccines is that they target different types and models of HPV viruses: Gardasil targets high-risk HPV viruses 16 and 18, and low-risk HPV viruses 6 and 11, of which HPV 16 and 18 are mainly the causes of cervical cancer in women, and HPV 6 and 11 are mainly related to genital warts; Huuyan Kang only targets HPV 16 and 18. The age requirement for both vaccines is 9 years old or above. The Huuyin Kang vaccine can be given only twice to vaccinees between the ages of 9 and 14 years old, and the vaccination period is 6 months after the first vaccination. For those over 14 years old, the second vaccination should be completed one month after the first vaccination and the third vaccination 6 months after the first vaccination. The Plus l vaccine is given 3 times, at the time of the first vaccination, 2 months after the first vaccination, and 6 months after the first vaccination. In the United States, the United Kingdom, Japan and other countries, the Plusl vaccine is included in their national health insurance for free vaccination, while Huoyancon is included in the health insurance of Belgium, the Netherlands, Italy and other countries. According to the 2014 brochure data, the proportion of vaccination in the world is higher for Plusl vaccine compared to Huoyancon, showing 160 million and 36 million for Huoyancon. I personally chose to receive the Plus vaccine because of the advantage of HPV prevention type and global vaccination volume. 2. Vaccination precautions I did some research before I went there. The cervical cancer vaccine is generally a very safe vaccine and the side effects are generally pain, swelling, erythema, itching, bruising and fever at the injection site, and the reactions are very mild. After I received the vaccination, I felt nothing but a slight pain at the injection site, and went shopping directly after 15 minutes of observation at the clinic, and the doctor did not say anything except not to drink alcohol that night. However, this vaccine also has the following most important injection instructions: If you have a fever, do not receive the vaccine, consult your doctor and receive the vaccination after you have recovered from the illness. Pregnant women should not be vaccinated, and should avoid pregnancy during the vaccination period, and should contact their doctor to stop or postpone subsequent injections if they become pregnant. Those who are allergic to these two vaccines should not be vaccinated.
