HPV vaccination can reduce the incidence of cervical cancer. HPV vaccines are currently categorized as 2-valent, 4-valent, and 9-valent, all of which have certain age restrictions. 4-valent is available to women aged 9 to 45 years old, and 9-valent is available to women aged 16 to 26 years old.
The 4-valent HPV vaccine prevents 70% of cervical cancers and 90% of genital warts, and the 9-valent HPV vaccine prevents 90% of cervical cancers and 90% of genital warts.
Whether it is the 4-valent or 9-valent HPV vaccine, the vaccination procedure is the same, and the whole process of vaccination requires 3 injections. After the first injection, the second injection will be given 2 months later, and the third injection will be given 6 months later.
It is important to note that HPV vaccination is not recommended for pregnant women, women with acute infections, and women with severe liver or renal insufficiency. Adverse reactions such as local redness, swelling and pain, dizziness and nausea may occur after vaccination.
It is also important to pay attention to the aseptic operation procedure when receiving the vaccination, and after the vaccination, you need to stay for 30 minutes, and you can leave if you feel no discomfort.
