Introduction
Generally speaking, there is no such thing as "the top ten taboos after vaccination." However, precautions after vaccination include avoiding immediate bathing, strenuous exercise, consuming irritating foods, taking medications arbitrarily, and rubbing the injection site. It is recommended to remain at the vaccination site for 30 minutes of observation to ensure there are no adverse reactions before leaving.
Generally speaking, there is no such thing as a "list of the top ten taboos after vaccination." However, certain precautions should be taken after vaccination, including avoiding immediate bathing, strenuous exercise, consuming irritating foods, taking medications arbitrarily, and rubbing the injection site. The details are as follows:
1. Avoid immediate bathing: After vaccination, tiny puncture wounds remain at the injection site. Bathing immediately may expose these wounds to contaminated water, increasing the risk of local infection. It is generally recommended to wait at least 24 hours and ensure there is no redness, swelling, or discharge before bathing.
2. Avoid strenuous exercise: The body needs time to develop an immune response after vaccination. Strenuous physical activity may increase bodily stress and cause sweating, which can leave the injection site damp and raise the risk of infection. It is advisable to engage only in light activities for 1–2 days following vaccination.
3. Avoid consuming irritating foods: Spicy, greasy, raw, or cold foods, as well as allergenic foods like seafood and mangoes, may stimulate the body. Some individuals may experience discomfort after eating these, which could interfere with identifying potential vaccine side effects. A light diet is recommended shortly after vaccination.
4. Avoid taking medications arbitrarily: Mild symptoms such as low-grade fever or fatigue after vaccination are usually normal reactions. Taking antipyretics, painkillers, antibiotics, or other drugs without medical advice may interfere with the body's ability to produce antibodies in response to the vaccine. Medication should only be taken under professional guidance.
5. Avoid rubbing the injection site: Rubbing or massaging the vaccination site may damage local tissues, worsen symptoms such as redness and pain, and potentially disrupt the normal action of the vaccine at the site. Care should be taken to protect the injection area and avoid mechanical irritation.
After vaccination, it is recommended to stay at the vaccination site for 30 minutes of observation to ensure no adverse reactions occur before leaving. In daily life, adequate rest, regular sleep patterns, and drinking plenty of warm water are advised to help the body adapt better to the vaccine and ensure optimal immune response.
