Worried about reactions after vaccination?

Please look here!

Vaccination is the most economical, effective and convenient measure to prevent and control infectious diseases. Due to individual differences among vaccine recipients, a small number of people may experience vaccination reactions. How can we correctly understand vaccination reactions? The editor has summarized professional answers to 6 common questions.

1. What reactions may occur after vaccination?

Vaccination reaction refers to a reaction caused by the characteristics of the vaccine itself, related to individual differences of recipients, and unrelated to the purpose of vaccination, including normal reactions and abnormal reactions.

Normal reactions mainly refer to transient reactions caused by the inherent characteristics of the vaccine itself, such as fever, local redness, swelling, nodules, etc. Abnormal reactions mainly refer to adverse drug reactions caused by qualified vaccines during or after standardized vaccination, which are caused by damage to the recipient's body tissues, organs, and functions, and are not the fault of all parties involved. They rarely occur, such as acute severe allergic reactions.

2. Why might a small number of people have reactions after vaccination?

After vaccination, while the vaccine induces the human immune system to produce protection against specific diseases, a small number of recipients may react after vaccination due to individual differences in recipients, such as poor health, allergies, etc., and the biological characteristics of the vaccine itself, such as additives in the vaccine.

3. What measures do recipients usually need to take after a vaccination reaction occurs?

If the vaccine recipient suspects that a vaccination reaction has occurred, the symptoms are mild, such as transient fever, redness, swelling, and pain at the injection site, which can generally be relieved on their own without treatment. If the symptoms worsen or persist, you should go to the hospital for diagnosis and treatment in time. If the vaccine recipient suspects that the discomfort symptoms may be related to the vaccination, you can consult the vaccination unit.

4. Why do you need to stay for observation for 30 minutes after vaccination?

After vaccination, a very small number of people may experience acute allergic reactions, fainting and other symptoms. These rare symptoms usually occur within 30 minutes after vaccination. Medical institutions are equipped with emergency equipment and professional medical personnel. If they occur, they can be dealt with in time at the observation site. Therefore, the vaccine recipients need to consciously observe in the designated area of ​​the vaccination unit for 30 minutes after vaccination.

5. What does coincidence syndrome mean?

Coincidence refers to the situation where the vaccine recipient is in the incubation period or early stage of the disease during the vaccination process, and the disease coincidentally occurs after vaccination. Therefore, coincidence is not caused by vaccination, has nothing to do with vaccination, and is not an abnormal reaction after vaccination, such as the disease caused by other bacterial or viral infections.

6. Is the vaccine safe?

Whether it is a domestic or imported vaccine, pre-market clinical research is strictly carried out in accordance with the requirements of the National Medical Products Administration. The production process complies with the requirements of the "Good Manufacturing Practice for Pharmaceuticals". Each batch of vaccines is strictly approved for batch release before being put on the market. Based on the results of early clinical trials of vaccines and information collected from large-scale population use, the vaccine has good safety and the general public can be assured of vaccination, but recipients with special physical conditions are recommended to be vaccinated after evaluation by a professional doctor.
