The New Crown vaccine is not a problem and is safe for most people to receive. People who are suffering from fever, acute illness, acute exacerbation of chronic diseases, or uncontrolled severe chronic diseases, and people who are allergic to vaccine ingredients are not allowed to receive the vaccine. Xin Guan vaccines are produced by qualified manufacturers approved by the state in accordance with strict production processes, so there is no problem in terms of quality. Some patients may be allergic to the vaccine ingredients, or have adverse reactions such as fever, skin redness and swelling, but this is not a problem with the vaccine itself, and most of them will be relieved on their own in 2~3 days. Before vaccination, you can ask your medical professional whether you can be vaccinated. After vaccination, you should stay for a certain period of time, and be sure to seek medical treatment when you have uncomfortable symptoms. Within one week after the vaccination, you should eat a light diet and avoid spicy and greasy food, so as not to induce or aggravate the adverse reaction of the vaccine, and at the same time, get enough rest and avoid exertion.
