In general, after vaccination, to ensure the effectiveness of immunization and minimize adverse reactions, it is important to follow certain precautions, including staying for 30 minutes of observation, properly caring for the injection site, adjusting diet, avoiding strenuous exercise, and monitoring physical responses. Vaccine recipients should maintain a regular daily routine, avoid staying up late, and strictly adhere to the above recommendations. If there are any special underlying medical conditions,
Under normal circumstances, after receiving a vaccine, to ensure its effectiveness and minimize adverse reactions, it is important to follow certain precautions, including staying for 30 minutes of observation, properly caring for the injection site, adjusting diet, avoiding strenuous exercise, and monitoring bodily reactions. A detailed explanation is as follows:
1. Stay for 30 minutes of observation: After vaccination, remain at the vaccination site for 30 minutes. This is because some individuals may experience acute reactions such as allergic responses shortly after injection. Staying allows medical staff to provide prompt treatment if needed, reducing potential risks. If no abnormal symptoms occur within this period, you may then leave.
2. Care for the injection site: Avoid getting the injection site wet within 24 hours after vaccination. Keep the area clean and dry to prevent bacterial infection. Mild redness, swelling, or pain at the site are common reactions—do not scratch or squeeze it, as these symptoms typically resolve on their own within 1–2 days.
3. Adjust diet: For 1–2 days after vaccination, avoid spicy, irritating foods, seafood, and other allergenic foods. Also avoid alcohol, strong tea, and coffee. Opt for light, easily digestible meals and consume more fresh vegetables and fruits to help maintain overall well-being.
4. Avoid strenuous exercise: Refrain from intense physical activities such as running, swimming, or ball games within 24 hours after vaccination, and avoid overexertion. Excessive activity may worsen discomfort at the injection site and could potentially affect the body’s immune response to the vaccine.
5. Monitor bodily reactions: Mild fever, fatigue, or headache may occur after vaccination. These are usually mild and short-lived; adequate rest is generally sufficient for recovery. However, if your temperature exceeds 38.5°C or symptoms persist for more than three days, seek medical attention promptly.
Vaccinated individuals should maintain regular sleep patterns and avoid staying up late, strictly following the above recommendations. Those with underlying medical conditions should communicate fully with healthcare providers before and after vaccination.
