What Should You Pay Attention to Before and After Receiving the COVID-19 Vaccine?
Vaccines are biological products prepared from various pathogenic microorganisms and used for preventive immunization. The COVID-19 vaccine is specifically designed to protect against the novel coronavirus (SARS-CoV-2). Below, we address key considerations before and after receiving the COVID-19 vaccine.

Key Considerations Before and After Receiving the COVID-19 Vaccine
1. Prior to vaccination, recipients should familiarize themselves with the local vaccination site’s appointment procedures, operating hours, and necessary preparations.
2. Recipients must bring valid identification documents (e.g., ID card) to the vaccination site; those with an official immunization record book should also bring it.
3. Recipients must truthfully inform the vaccinating healthcare provider of their recent health status so that the provider can determine eligibility for vaccination.
4. Note: After vaccination, recipients must remain at the vaccination site for 30 minutes of post-vaccination observation.
5. Following vaccination, if fever or local reactions occur—such as a temperature exceeding 38.5°C or injection-site redness/swelling measuring greater than 2.5 cm in diameter—recipients should promptly seek medical attention and report the symptoms to the vaccinating healthcare provider.
Additional Information: Contraindications for the COVID-19 Vaccine Booster Dose
1. Individuals with known allergies to any active ingredient, inactive ingredient, or substance used in the manufacturing process of the vaccine—or those who experienced allergic reactions following prior administration of the same type of vaccine;
2. Individuals with a history of severe allergic reaction to vaccines (e.g., acute allergic reaction, angioedema, respiratory distress);
3. Individuals with uncontrolled epilepsy or other serious neurological disorders (e.g., transverse myelitis, Guillain-Barré syndrome, demyelinating diseases);
4. Individuals currently experiencing fever, suffering from an acute illness, undergoing an acute exacerbation of a chronic condition, or living with uncontrolled severe chronic disease;
5. Pregnant women or those actively trying to conceive.
The above outlines essential considerations before and after receiving the COVID-19 vaccine. We hope this information proves helpful to you.
