Cervical cancer vaccine quadrivalent vaccination age

The age group for cervical cancer quadrivalent vaccination is generally between 20 and 45 years old. The effect of the quadrivalent vaccine on women under 20 years old has not yet been fully verified, and the effect may decrease on women over 45 years old.

20-45 years old is the standard vaccination age group for the quadrivalent cervical cancer vaccine. The quadrivalent vaccine protects against cervical cancer caused by human papillomavirus types 16 and 18, and genital warts caused by types 6 and 11. When vaccinated in this age group, the vaccine has a better protective effect and can effectively reduce the risk of cervical cancer. For women who are not sexually active, the vaccination effect is more ideal. Women who are already sexually active can also be vaccinated, but the protective effect may be reduced. There is no need to take an HPV test before vaccination. Even if you are infected with one type of HPV, you can still get vaccinated to gain protection against other types.

Women under 20 years old are not recommended to receive the quadrivalent vaccine. This group of people is more suitable to receive the nine-valent vaccine, because the nine-valent vaccine has a protective effect against more HPV types and is more effective in younger people. The effect of the quadrivalent vaccine on women over 45 years old is limited. The immune response of these women may be weak, and most of them may have acquired a certain degree of immunity through natural infection. Women over the age of 45 should pay more attention to regular cervical cancer screening.

After receiving the cervical cancer vaccine, you still need to have regular cervical cancer screenings because the vaccine cannot prevent all types of HPV that cause cervical cancer. Maintaining good personal hygiene and healthy sexual behavior can help prevent HPV infection. Quitting smoking and drinking, eating a balanced diet, and exercising moderately can enhance immunity and reduce the risk of cervical cancer. After vaccination, you should pay attention to observe whether there are any adverse reactions, such as redness, swelling, pain or fever at the injection site. Usually these symptoms will resolve on their own within a few days.
