Disease description:

I found out during a skin test at the hospital before that I am allergic to penicillin, so I have never taken penicillin since. However, as the school is organizing vaccinations for students, I would like to ask whether people with drug allergies can receive vaccinations?

Drug allergy generally contraindicates vaccination, especially during the acute phase of an allergic reaction. Drug allergies may cause symptoms such as skin swelling, red patches, and severe itching. Receiving a vaccine during an allergic episode could worsen physical discomfort and potentially trigger other adverse reactions. Additionally, individuals with drug allergies often have sensitive constitutions, which may increase the risk of adverse reactions following vaccination, possibly leading to life-threatening situations. However, this does not mean that individuals with drug allergies can never receive vaccines. After the allergic symptoms have been controlled and stabilized, and if a physician's evaluation determines that vaccination is appropriate, individuals with drug allergies may still consider receiving vaccines. Before vaccination, it is essential to truthfully inform the physician about one's allergy history and current health status.
