Domestic New Crown vaccine has some side effects, but only some people will have adverse reactions.
Some common adverse reactions may occur after vaccination with the domestically produced New Crown vaccine, such as redness, swelling and pain at the site of vaccination, etc. A very small number of people may experience fever, fatigue, nausea, headache, muscle pain, etc. due to individual differences, which are usually relieved by themselves within 2 to 3 days, and do not usually require special treatment.
The new crown vaccine, like other vaccines, has to undergo animal experiments, phase I clinical trials, phase II clinical trials and phase III clinical trials during the development of the vaccine, in which the vaccine will be evaluated to see whether and to what extent it will produce adverse reactions in animals and humans. Our New Crown vaccine has a good safety profile and the number of adverse reactions is low.
If the symptoms are severe or if you are unable to assess the severity on your own, you should seek medical attention.
