How to effectively prevent the stress response of vaccines

Vaccine stress response refers to the fact that during the vaccination process, the body is also damaged to a certain extent while the body produces an immune response. From the perspective of actual immunization effect, under normal circumstances, after the injection of livestock and poultry vaccines, stress reactions such as high body temperature, decreased diet, and increased mortality rate often occur, which will generally return to normal after 3 15 days of injection, and individual will delay for a longer period of time, resulting in unnecessary economic losses. In order to effectively reduce or avoid the stress caused by immunity, first of all, it is necessary to strengthen the immune awareness of breeding personnel and standardize the operation process.

Properly transport and store vaccines, maintain vaccine equipment, disinfection and sterilization; Make full preparations before immunization, strictly and correctly follow the immunization program and vaccine instructions, the vaccine is ready for use, sterile immunization, correct injection, and drinking water immunization is controlled within 2 hours. Secondly, it is necessary to strengthen nutrition and maintain the health of pigs. 3 days before the injection of the vaccine, Hengfengqiang production of Victoria (500 ml to 1000 kg of water) and Dalian Sanyi Company's Jia Lijian (250 grams to 1000 kg of water) can play a great role in eliminating or alleviating the stress reaction, reducing the economic losses caused by the injection of many pig farmers, and also playing a positive role in the smooth progress of epidemic prevention work.

The stress response of the vaccine refers to the fact that during the vaccination process, the body itself is damaged to a certain extent while producing an immune response. In addition, improper use of vaccines can also cause more serious stress reactions to the body.

A small number of recipients may have fever within 24 hours after cerebral vaccination, generally lasting 1 2 days, rarely more than 3 days, a small number of recipients in addition to fever symptoms, may also appear headache, dizziness, fatigue, general malaise, etc., caused by the inherent characteristics of the vaccine itself, will only cause a transient physiological dysfunction reaction to the body, generally do not need any treatment.

If the body temperature is above the head, you can use the head cold compress, warm water scrub bath and other physical cooling or an appropriate amount of antipyretics, and if the high fever does not go away or is accompanied by other complications, the condition should be closely observed, and if necessary, send to the hospital**.

Vaccination reactions include general reactions, abnormal reactions, abnormal reactions, coincidental diseases, and vaccination accidents. (1) General reactions: within 24 hours of vaccination, there are local redness, swelling, pain, heat and other inflammatory reactions at the inoculation site, and sometimes nearby lymph nodes are swollen and painful.

The general reaction is a normal immune response, which does not require any treatment and disappears within 1 to 2 days. If the reaction is strong, only symptomatic ** is needed.

Your child's reaction is a general reaction and needs to be carefully observed, and you can also take a little fever reducer, and it will get better soon, so don't worry.

Vaccination reactions are divided into general reactions and abnormal reactions. The general reaction mainly includes fever, local redness and swelling, and may be accompanied by general malaise, fatigue, loss of appetite, fatigue and other syndromes, generally 2-3 days can recover on its own, it is recommended to observe, take antipyretic drugs if the body temperature exceeds the degree, if there are no other symptoms, you can continue to observe, drink more water!
