Introduction
In general, after receiving the COVID-19 vaccine, key precautions to pay attention to include staying for observation for 30 minutes, protecting the injection site, adjusting daily habits, monitoring bodily reactions, and completing all doses on schedule. Vaccination is an important measure for preventing and controlling COVID-19; strictly following these precautions not only ensures safety during vaccination but also helps the vaccine achieve optimal effectiveness.
Under normal circumstances, key precautions to take after receiving the COVID-19 vaccine mainly include staying for 30 minutes of observation, protecting the injection site, adjusting daily habits, monitoring bodily reactions, and completing all doses on schedule. 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. This is a critical safety measure. If any abnormal symptoms such as dizziness, palpitations, rashes, or difficulty breathing occur, medical staff can provide immediate professional assistance. Leaving before the full observation period is complete is not permitted.
2. Protect the injection site: Avoid getting the injection site wet within 24 hours after vaccination. Do not rub, press, or apply ointments to the area, to prevent skin damage and potential infection. Mild redness, swelling, or itching at the site are common local reactions and usually resolve on their own.
3. Adjust daily habits: Avoid strenuous exercise temporarily to reduce physical strain. Maintain a light diet by avoiding spicy, greasy foods and alcohol, which may increase bodily stress or trigger discomfort. Ensure adequate sleep to support optimal recovery.
4. Monitor bodily reactions: Pay attention to your condition during the first 1–2 days after vaccination. You may experience mild side effects such as low-grade fever, fatigue, or muscle aches, which typically resolve within 1–3 days. If symptoms worsen—such as persistent high fever above 38.5°C—seek timely symptomatic treatment.
5. Complete vaccination on schedule: Most COVID-19 vaccines require multiple doses according to a specific schedule. It is essential to receive all subsequent doses exactly as instructed by healthcare providers. Do not advance or delay appointments arbitrarily. Only by completing the full course can you achieve comprehensive and lasting protection.
Vaccination is a crucial measure in preventing and controlling COVID-19. Strictly following these precautions ensures both safety and optimal vaccine effectiveness. Even after vaccination, continue practicing personal protective measures, such as wearing masks and frequent handwashing.
