It is recommended that vaccinees contact their local medical institutions in advance to clarify what tests need to be completed before the quadrivalent cervical cancer vaccination to avoid delays in the vaccination. 1. Basic tests: such as heart rate, body temperature, blood pressure and other basic vital signs tests, to avoid aggravation of symptoms after the vaccination. 2. It is recommended that vaccinators should undergo allergy testing in advance. If they have protein allergy, they should be cautious about injecting quadrivalent cervical cancer vaccine to avoid allergy symptoms such as rash, skin redness and swelling, fever, etc.; 3. Conduct liquid-based thin-layer cytology test, i.e. TCT test, etc., to detect whether there are HPV virus antibodies in the body. If a vaccinator has HPV infection, it is usually not recommended to receive the quadrivalent cervical cancer vaccine. 4. Pregnancy test: The quadrivalent cervical cancer vaccine cannot be administered during pregnancy, so it is recommended that the vaccinator take an early pregnancy test or undergo HCG test or ultrasound examination before vaccination to rule out the possibility of pregnancy. The examinations required before quadrivalent cervical cancer vaccination vary from place to place, so it is recommended that vaccinators consult with the relevant medical institutions in the place of vaccination to clarify what examinations need to be completed.
