Adverse reactions after vaccination

Most children have no or very mild reactions after receiving vaccination. A small number of children may experience mild adverse reactions, some of which are normal reactions, including local and systemic reactions. Local reactions are redness, swelling, heat, pain, or local lymphadenopathy at the injection site. Systemic reactions include local chills, fever, headache, loss of appetite, vomiting, abdominal pain, etc. These conditions generally do not require treatment. As long as the child drinks more water and reduces activity, these reactions will disappear after 1 to 2 days.

Abnormal reactions occur simultaneously or successively with the general reactions mentioned above, but only occur in individuals or a few people. The number of occurrences is closely related to the type of vaccine and the physical condition of the vaccine recipient. Abnormal reactions include the following three types: 1) angioedema and anaphylactic shock; 2) allergic reactions of the nervous system; 3) needle phobia, etc. Although the incidence of abnormal reactions is very low, parents should still pay attention to whether their children are highly nervous or have allergic constitutions. If needle phobia or anaphylactic shock occurs, the child should be laid flat, given warm water or sugar water orally, with the head lowered, and appropriate emergency symptomatic treatment measures should be taken.

It is normal for children to experience low fever, redness, swelling and nodules at the needle holes after vaccination, which usually appear about 24 hours after vaccination. Severe reactions at the injection site can cause inflammation of nearby lymph nodes and lymph vessels. The range of swelling and nodules at the injection site is divided into mild, moderate and severe. A mild reaction is less than 2.5 cm in diameter, a moderate one is between 2.5 and 5 cm in diameter, and a reaction greater than 5 cm is a severe reaction, which can last for several hours or days. If the local redness and swelling are severe, you can apply hot compress (hot compress is strictly prohibited for redness and swelling after BCG vaccination). Once in the morning and once in the evening, each time for about 5 minutes. And you should change your underwear frequently to avoid infection after ulceration. If there is local infection, apply gentian violet solution. These symptoms can be treated with warm compresses or go away on their own within a day. For example, for the measles vaccine, most recipients will not have any special reaction. Some people will have local swelling and pain for 1-2 days. About 5% of children will develop a rash 1-2 weeks after vaccination. 5-10% of children will have a fever 4-10 days after vaccination, with mild temperatures ranging from 37 to 37.5℃ and moderate temperatures ranging from 37.6 to 38.5℃. Temperature above 39℃ is severe. In addition, some children may have symptoms such as "headache, dizziness, general weakness, chills, nausea, vomiting, abdominal pain, diarrhea, etc. The above reactions usually subside within 24 hours and rarely last for more than 3 days. If the fever is severe, you can take antipyretics. Generally, after the body temperature returns to normal, other symptoms will subside on their own. If the high fever does not subside or there are other abnormalities, you should be sent to the hospital for diagnosis and treatment in time.

Adverse reactions to leprosy vaccines are also very common. Some children will experience some uncomfortable symptoms after being injected with leprosy vaccines. Generally, such phenomena will disappear on their own within 2 days and usually do not require treatment. If the situation is serious, everyone should go to the hospital for examination and treatment in time to avoid more serious consequences.
