Can someone with a penicillin allergy receive the 9-valent HPV vaccine?
Patients allergic to penicillin can still receive the 9-valent HPV vaccine. Individuals with penicillin allergy should also avoid cephalosporin antibiotics. However, vaccines primarily contain inactivated viruses and generally do not cause allergic reactions.
The 9-valent HPV vaccine helps prevent cervical cancer caused by human papillomavirus (HPV) infection. It protects against nine HPV types—6, 11, 16, 18, 31, 33, 45, 52, and 58—which account for over 90% of cervical cancer cases. Since the 9-valent HPV vaccine contains only inactivated virus and does not include cephalosporins or related components, individuals with penicillin allergy can safely receive this vaccine as usual.
After receiving the 9-valent HPV vaccine, some individuals may experience adverse effects such as nausea, vomiting, headache, or drowsiness. Therefore, it is important to get adequate rest, avoid staying up late, ensure sufficient sleep to support recovery, refrain from strenuous exercise in the short term, and maintain a light diet. Spicy, stimulating, raw, or cold foods should be avoided.
