Do I still need to check antibody levels after receiving the quadrivalent vaccine?

Introduction
In general, "quadrivalent" refers to the quadrivalent HPV vaccine, and whether antibody testing is needed depends on the specific situation. If patients are concerned, antibody testing is usually recommended; if they are not concerned, antibody testing may not be necessary. Patients who are worried can undergo antibody testing for the quadrivalent HPV vaccine, as issues such as expiration of the quadrivalent HPV vaccine or incomplete administration of the full vaccine series may occur.
Generally speaking, "quadrivalent" refers to the quadrivalent HPV vaccine. Whether antibody testing is needed depends on individual circumstances. If patients are concerned, they usually need to have their antibodies checked; if not concerned, antibody testing may not be necessary. The specific analysis is as follows:
1. Testing
If patients are concerned, they can undergo antibody testing for the quadrivalent HPV vaccine. This is because factors such as expired vaccine or incomplete administration of all four doses might prevent adequate antibody production. Therefore, there is some justification for checking antibody levels after receiving the quadrivalent HPV vaccine. Patients can have a blood test after completing the vaccination series to determine whether antibodies against the quadrivalent HPV strains have developed.
2. No testing
Antibody testing is generally not required after receiving the quadrivalent HPV vaccine, as, except in rare cases, most individuals will develop sufficient antibodies following vaccination. Thus, it is acceptable not to check antibody levels after completing the quadrivalent HPV vaccine series. The quadrivalent HPV vaccine primarily prevents diseases caused by HPV types 6, 11, 16, and 18, including cervical cancer and precancerous lesions. After vaccination, most people develop adequate immunity to protect against infection from these HPV types.
If patients experience any symptoms or discomfort, they should promptly seek medical attention at a hospital to avoid delays in diagnosis and treatment.
