What are the adverse reactions after taking the sugar-coated polio vaccine pill?
Disease description:
Speaking of the polio vaccine, I recall that as a child, we were given an oral vaccine in the form of a sweet-tasting pill—commonly referred to as a “sugar cube.” It’s no longer available today. I remember some children developed fever after taking it. Could you please tell me what adverse reactions might occur following administration of this oral polio vaccine?

Mild adverse reactions may occur after taking the oral polio vaccine (OPV) sugar cube; however, severe adverse reactions are rare. Within 1–2 days after vaccination, some children may experience vomiting, nausea, diarrhea, or fever; rash is a less common adverse reaction. Mild adverse reactions typically resolve spontaneously within 2–3 days and do not require specific treatment. Only severe adverse reactions necessitate symptomatic management. The OPV sugar cube is primarily used to prevent poliomyelitis.
