Bivalent vaccine usually refers to the bivalent HPV vaccine, which requires a total of three injections. Currently, there are bivalent, quadrivalent and nine-valent HPV vaccines available in China, which are mainly used to prevent human papillomavirus (HPV) infections, and all three vaccines require three injections. The bivalent vaccine is for women between the ages of 9 and 45 and prevents high-risk types of HPV16 and HPV18 infections. After the first injection, a second injection is required after one month, and a third injection is required by the sixth month. Timely and complete injections will help stimulate the body to produce antibodies and better perform the preventive function, so it is important to pay attention to vaccination on time. Quadrivalent vaccine and nine-valent HPV vaccine, these two vaccines are given after the first injection, the second injection in two months, and the third injection in the sixth month. After the vaccination, pay attention to a light diet, do not eat spicy stimulating cold food. Don’t stay up late, avoid getting cold, and get enough sleep. It should be reminded that even after HPV vaccination, married women should have regular cervical cancer screening, usually once a year.
