Introduction
In general, whether a breastfeeding woman can receive a COVID-19 vaccine booster should be determined based on her individual health condition. It is important to ensure adequate sleep and avoid excessive fatigue that may affect recovery. In terms of diet, consume more high-quality protein and vitamins to enhance the body's immunity. After vaccination, monitor the injection site for redness, swelling, or pain, and keep the area clean and dry.
Generally, whether a breastfeeding woman can receive a booster dose of the COVID-19 vaccine should be determined based on her individual health condition. The specific analysis is as follows:
If a breastfeeding woman is in good health, without symptoms such as fever or acute mastitis, and has not experienced severe allergic reactions to previous doses of the COVID-19 vaccine, she may receive the booster after evaluation by a healthcare provider. Breastfeeding does not need to be discontinued after vaccination. Vaccine components rarely enter breast milk, and current research has not found any adverse effects on infants. Before vaccination, it is important to inform the doctor about breastfeeding status and personal medical history.
Women who are experiencing an acute illness, such as high fever or severe respiratory infection, those with uncontrolled serious chronic conditions, or those with a clear history of allergy to vaccine components should not receive the booster. They should first actively treat their underlying condition and wait until their health stabilizes or contraindications resolve before a doctor reassesses eligibility for vaccination.
Maintain adequate sleep and avoid excessive fatigue to support recovery. Eat a balanced diet rich in high-quality protein and vitamins to strengthen immunity. After vaccination, monitor the injection site for redness, swelling, or pain, and keep the area clean and dry. If mild side effects occur, rest more and drink plenty of water; seek medical attention promptly if symptoms persist.
