HPV FAQ
Getting vaccinated early can help reducing the chance of getting HPV. Since HPV virus is mainly transmitted through sexual contact, vaccination before sexual contact can provide stronger protection. The 9 to 14-year-old vaccination can produce a stronger immune response, so it should be prepared in advance.
Even if there is only one sexual partner, there is still a 60% risk of infection, and the use of condoms still cannot completely prevent infection. If you are unfortunately infected with HPV, it is more likely to affect future fertility and even the next generation.
The HPV 9-in-1 vaccine cannot be vaccinated during pregnancy. If you find that you are pregnant after starting the vaccination, you should postpone the vaccination. HPV infection has the chance of mother-to-child transmission, and women can get vaccinated according to the doctor's advice before planning pregnancy.
HPV 9-in-1 vaccine can be given while women are breastfeeding their child.
Even if you have been infected with HPV, it does not necessarily mean that you have been infected with all preventable types of HPV, so vaccination can still help to prevent some virus types that have not been infected.
Studies have shown that there is continuous protection after vaccination with the HPV 9-in-1 vaccine, and there is currently no data showing the need for booster doses.
Children aged 9-14 only receive 2 doses of HPV vaccine, will the immune response be insufficient?
Studies have shown that the immune response of school-age children receiving 2 doses of HPV vaccine is similar to that of 3 doses.
How safe is the HPV vaccine?
WHO has endorsed the safety of two HPV vaccines.
Both vaccines do not contain viral genes or any infectious substances, and will not cause HPV infection or related diseases.
In clinical studies, the common side effects of the two vaccines were pain at the injection area, swelling, erythema, itching and fever, all of which were mild. Ask your doctor for details (such as rare side effects) as they have extensive side effect information.
Does the HPV vaccine have cross protection?
After reviewing the existing medical literature, WHO believes that the two vaccines can also provide a certain degree of protection against HPV viruses outside their coverage. Taking HPV 16 and 18 as an example, because the gene sequence of the two vaccines is similar to that of HPV 31 and HPV 45 is similar, so after injection, in addition to preventing HPV16 and 18, it can also bring some cross-protection to similar types of viruses such as HPV 31 and 45. In fact, both vaccines have clinical data on cross-protection. Taking the 4-in-1 vaccine as an example, it can help prevent 10 types of HPV31, 33, 35, 39, 45, 51, 52, 56, 58 and 59 to a certain extent. Cervical precancerous lesions, stage two and three high-grade precancerous lesions, and adenocarcinoma in situ of the uterus. Ladies should be aware of the two existing HPV vaccines that are effective in preventing the related HPV diseases covered by the vaccines; but most importantly, ladies should not forget to perform regular cervical smear examinations after vaccination.
Who should not be vaccinated (or temporarily)?
Allergic reaction to HPV cervical cancer vaccine
Those who are allergic to yeast
Pregnant women
People with fever, moderate or severe illness should wait until they have recovered before getting vaccinated
