What are the reactions after receiving the BCG vaccination?
After the injection of BCG vaccine, the human body usually does not have severe reactions, but the injection site may become red and swollen, and later may develop into pus. When a small pustule appears at the injection site of BCG vaccine, it is crucial not to squeeze the pustule, which may affect the effectiveness of the injection and increase the risk of wound infection. The injection of BCG vaccine has certain requirements for the recipient's body, so it is necessary to consult the doctor for relevant information and avoid blind injection.
What are the symptoms after BCG vaccine injection? 1. Local reaction: There may be slight redness and swelling within 2-3 days after vaccination, which will quickly disappear. After another two to three weeks, a red and swollen lump may appear at the injection site, which will then turn into a pustule and scab, forming a small scar. 2. Lymph node reaction: It is mainly manifested as enlarged lymph nodes in the axillary region, above and below the clavicle near the injection site. With the healing of the injection site, the enlarged lymph nodes will gradually subside, and hot compress can also be used to help reduce the swelling.
What are the precautions before BCG vaccination? 1. Before vaccination, it is important to truthfully inform the doctor about the child's physical health status. If there are symptoms such as colds or fever, the vaccination should be rescheduled after recovery. 2. For those who have received immunoglobulin injections, there should be at least a one-month interval before receiving this vaccine to avoid affecting the immune effect. 3. The following situations should be used with caution: family and personal history of convulsions, chronic diseases, epilepsy, allergic constitution, and lactating women.
