What should patients do if they experience severe reactions after vaccination?

Patients who experience severe reactions after vaccination should seek immediate medical attention because severe reactions can indicate serious health risks, such as an allergic reaction or anaphylaxis. These conditions can develop rapidly and may require prompt intervention, including administration of medications like epinephrine, monitoring, or other medical procedures to ensure the patient's safety.

In contrast, waiting to see if symptoms improve could delay critical treatment. Notifying only friends doesn't provide the patient with the necessary medical care they may need. Contacting the pharmacy later is also inadequate, as any significant symptoms typically warrant urgent attention rather than postponing care. Proper recognition and timely response are essential to managing potential vaccination-related complications effectively.
