The third dose of the New Crown vaccine has no effect on healthy women and may cause some common side effects such as redness, swelling, and low-grade fever. The New Crown Vaccine is a fully viral inactivated vaccine. If a healthy woman is not allergic to the components of the vaccine, there are usually no particular effects. Some women may experience common side effects such as slight redness, swelling, pain and low-grade fever at the injection site, etc. These symptoms usually disappear on their own in 2 to 3 days and do not require special treatment. Some women may also experience slightly more serious side effects, such as high fever, abdominal pain, skin rash, etc. Worse still, they may experience difficulty in breathing and a drop in blood pressure. This is usually less common and patients need to seek medical treatment promptly. Be careful to observe the patient in the observation area for 30 minutes after receiving the New Crown vaccine and inform the healthcare provider promptly if there is any discomfort. The third dose of New Crown vaccine is not recommended if you are pregnant.
