Generally, whether one can receive the COVID-19 vaccine after taking Compound Liquorice Tablets depends on individual circumstances. If in doubt, it is recommended to consult a doctor. The specific analysis is as follows:

 

If someone has taken Compound Liquorice Tablets for mild coughing that has significantly improved, and there are no other symptoms such as fever or fatigue, vaccination may be considered safe after medical evaluation. In such cases, the person's overall health is stable, the dosage and duration of medication are low and short-term, and the impact on the immune system is minimal. This will not interfere with the process of antibody production induced by the vaccine, and standard vaccination can ensure effective immunity.

Vaccination is not recommended during an acute illness phase—such as severe coughing or high fever—or if taking Compound Liquorice Tablets due to worsening chronic conditions. At this time, the body's immune system is already highly active; receiving the vaccine may exacerbate existing symptoms and potentially impair immune response. It is advisable to wait until the condition stabilizes, symptoms subside, and a certain period has passed after stopping the medication before scheduling vaccination.

Maintain a light diet, drink plenty of warm water, ensure adequate rest, and avoid fatigue around the time of vaccination. Keep the injection site clean. If persistent redness, swelling, or fever occurs, contact healthcare professionals promptly.
