What Should You Pay Attention To Immediately After Receiving the COVID-19 Vaccine?

The novel coronavirus (SARS-CoV-2) is highly contagious and pathogenic, and can readily cause life-threatening complications. To proactively prevent and control outbreaks of COVID-19, national health authorities recommend that all eligible individuals complete their COVID-19 vaccination as soon as possible. So, what precautions should you take immediately after receiving a COVID-19 vaccine? Below, we address this question.

What to Pay Attention to Immediately After Receiving a COVID-19 Vaccine

1. Observe for 30 Minutes Post-Vaccination

After vaccination, you must remain at the vaccination site for observation for 30 minutes. During this period, if you experience symptoms such as pallor, sweating, cold and clammy extremities, rash, weak and rapid pulse, cyanosis, facial or throat swelling, or difficulty breathing, immediately notify the on-site healthcare provider. Used cotton swabs for hemostasis should be disposed of in designated medical waste bins or yellow medical waste bags. Additionally, common post-vaccination reactions—including fever, local redness, swelling, or pain—are generally mild and self-limiting. However, if you develop high fever or persistent fever lasting several days, seek prompt medical evaluation at a hospital.

2. Maintain a Light Diet

Due to individual variability, some people may experience post-vaccination symptoms such as fever, fatigue, nausea, or headache. To avoid exacerbating these symptoms, avoid known personal allergens and common allergens for one week following vaccination. Refrain from alcohol consumption and avoid spicy, stimulating, or seafood-based foods. Instead, opt for light, easily digestible meals and increase fluid intake. Furthermore, blood donation is not recommended during the COVID-19 vaccination period. Individuals who have recently received influenza or COVID-19 vaccines should defer blood donation for at least 28 days after completing vaccination.

3. Avoid Bathing on the Day of Vaccination

Do not use alcohol-soaked cotton balls to press on the injection site; instead, apply gentle pressure with a dry cotton ball for one minute. Keep the injection site dry, and avoid bathing on the day of vaccination. Since the skin at the injection site is slightly compromised, bathing too soon increases the risk of localized skin infection or inflammation; therefore, it is advisable to wait at least 24 hours before showering. Additionally, avoid administering other inactivated vaccines within 14 days of your COVID-19 vaccination, and avoid live attenuated vaccines—including rabies vaccine, tetanus vaccine, and immunoglobulin—within 28 days.

The above outlines key precautions to observe immediately after receiving a COVID-19 vaccine. We hope this information is helpful to you.
