Introduction
Under normal circumstances, influenza refers to the flu; alcohol consumption is not recommended when receiving a flu vaccine. To ensure the effectiveness of the vaccine and reduce adverse reactions, it is advised to avoid alcohol consumption for one week after receiving the flu vaccine. Additionally, consumption of spicy and irritating foods such as chili peppers, ginger, and garlic should also be avoided. At the same time, it is important to maintain cleanliness at the injection site and avoid contact with water too soon after vaccination.

Generally speaking, influenza refers to the common flu. It is not recommended to consume alcohol after receiving an influenza vaccine. The specific reasons are as follows:

Alcohol contains a significant amount of ethanol and is considered a spicy and stimulating beverage. Consuming alcohol may interfere with the effectiveness of medications in the body, thereby reducing the efficacy of the vaccine. Drinking alcohol can also lead to a decline in immune function, which is detrimental to the production of antibodies in the body and may affect the effectiveness of vaccination. After receiving an influenza vaccine, the injection site might experience discomfort such as redness and pain. Alcohol consumption might further irritate the skin and worsen these symptoms.

Some individuals may experience adverse reactions such as dizziness, nausea, muscle pain, or rash after receiving the influenza vaccine. Similarly, individuals allergic to alcohol might also experience these symptoms after drinking, making it difficult to distinguish the cause, which could potentially affect treatment decisions.

To ensure the effectiveness of the influenza vaccine and reduce adverse reactions, it is recommended to avoid alcohol consumption for at least one week after vaccination. Additionally, consumption of spicy and stimulating foods such as chili peppers, ginger, and garlic should also be avoided. It is important to maintain cleanliness at the injection site and avoid contact with water too soon after vaccination.
