Can I drink tea after receiving the third vaccine shot?

Generally, whether one can drink tea after receiving the third vaccine dose depends on individual physical reactions and tea-drinking habits. If discomfort occurs, it is recommended to seek medical attention promptly. The detailed analysis is as follows:

If no adverse symptoms—such as fever, fatigue, or redness, swelling, and soreness at the injection site—occur after the third vaccine dose, and if one has a habit of regularly drinking tea, consuming a moderate amount of weak tea is acceptable. Light tea will not significantly affect the vaccine's immune efficacy nor add extra burden to the body. However, tea intake should be controlled, and drinking tea on an empty stomach should be avoided.

If symptoms such as fever, dizziness, or significant discomfort at the injection site occur after vaccination, or if one has inherently weak gastrointestinal function, drinking tea is not recommended. Components in tea such as caffeine and theophylline may irritate the gastrointestinal tract, worsen discomfort, and interfere with rest, thus hindering recovery. Tea consumption should only be considered after full symptom relief.

After vaccination, it is advisable to drink more warm water to replenish fluids and support metabolism. Avoid getting the injection site wet or rubbing it to reduce the risk of local infection. Maintain a light diet and temporarily avoid spicy and greasy foods to promote better digestion and absorption. Ensure adequate rest and avoid excessive fatigue to support optimal immune response. If discomfort persists after vaccination, prompt medical evaluation is necessary.
