After receiving the live influenza vaccine, the body's immune function may experience a temporary decline. Consuming seafood such as hairy crabs during this time may increase the risk of allergic reactions. Hairy crabs contain abundant proteins and other nutrients, which are more likely to trigger allergic reactions—such as skin itching, redness, swelling, fever, and dizziness—when immunity is lowered.

Hairy crabs are considered a cold-natured food in traditional dietary concepts and may cause gastrointestinal discomfort, potentially affecting the absorption and effectiveness of the live influenza vaccine. Moreover, if an allergic reaction occurs after eating, it could interfere with the observation and assessment of post-vaccination responses. Therefore, to ensure proper recovery and optimal vaccine efficacy, it is recommended to wait 24–48 hours after receiving the live influenza vaccine before consuming hairy crabs. This allows the body sufficient time to adapt to the vaccine, produce corresponding antibodies, and reduce the risk of allergic reactions.

After receiving the live influenza vaccine, avoid spicy and irritating foods. Maintain a light diet and drink plenty of water, which can promote metabolism and help eliminate toxins, thereby supporting the vaccine’s metabolism and effectiveness in the body.
