Introduction
In general, after vaccination, to ensure safety and effectiveness, key precautions include staying for observation for 30 minutes, protecting the injection site, adjusting diet, avoiding strenuous exercise, and monitoring bodily reactions. Vaccination is an important method for disease prevention, and strictly following these precautions helps ensure safety. After vaccination, individuals should continue daily protective measures and develop healthy lifestyle habits.
Generally, after vaccination, to ensure safety and effectiveness, key precautions include staying for 30 minutes of observation, protecting 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, it is mandatory to remain on-site for at least 30 minutes. Acute allergic reactions or other sudden adverse events may occur shortly after vaccination, most commonly at the vaccination site. Staying allows medical staff to promptly detect and manage any emergencies, reducing risks. Only leave if no abnormalities occur; immediately inform healthcare providers if you feel unwell.
2. Protect the injection site: Avoid exposing the injection site to water within 24 hours after vaccination, and keep it clean and dry. Do not scratch, press, or rub the area, to prevent skin damage and potential infection. Wear loose clothing to minimize friction on the injection site and avoid worsening redness, swelling, or pain.
3. Adjust diet: In the short term, maintain a light and easily digestible diet. Increase intake of fresh fruits, vegetables, and high-quality protein. Avoid spicy, stimulating, raw, cold, and greasy foods, as well as tobacco and alcohol, which may stimulate the body and exacerbate possible post-vaccination discomfort.
4. Avoid strenuous exercise: Refrain from intense physical activities such as running, swimming, or high-intensity workouts for 1–2 days after vaccination. Strenuous exercise may cause excessive fatigue and could strain the muscles around the injection site, leading to local pain or discomfort and delaying recovery.
5. Monitor bodily reactions: Mild side effects such as low-grade fever, redness, swelling, or pain at the injection site may occur but usually resolve on their own within 1–2 days. If persistent fever, pus at the injection site, rash, dizziness, or other unusual symptoms develop, contact the vaccination center or seek medical attention promptly.
Vaccination is an important method for disease prevention. Strictly following these precautions helps ensure safety. Even after vaccination, continue practicing daily protective measures and cultivate healthy lifestyle habits.
