What common side effect can result from the oral polio vaccine?

• A. Severe headache
• B. Mild fever and local soreness at the injection site
• C. Nausea and vomiting
• D. Anaphylaxis

Answer: (B)

The correct choice highlights mild fever and local soreness at the injection site as common side effects resulting from the oral polio vaccine. This is typically due to the body's immune response as it recognizes the weakened virus present in the vaccine. The mild fever can be a sign that the immune system is responding appropriately and building protection against the poliovirus. While reactions like severe headaches, nausea, vomiting, or anaphylaxis can occur with other vaccines or medications, they are not considered common or typical reactions associated specifically with the oral polio vaccine. The localized soreness is also a standard response, as many vaccines can cause some discomfort at the site of administration. Understanding these common side effects helps guide parents and caregivers in managing expectations after vaccination.
