The decision is based on physical condition, and vaccination is recommended for those who are in good health without serious acute diseases. The new crown vaccine is available for people over 18 years of age, including people over 70 years of age. For people over 70 years old, since there are not many clinical data, it is necessary to make a cautious judgment on whether to vaccinate or not after a thorough understanding of the physical condition. According to the current clinical research data, the vaccine’s protective ability for people over 70 years old is similar to that of the general population, and the safety of vaccination for this population is also good. If blood pressure, blood sugar, and cardiopulmonary function are maintained in a stable state, vaccination is recommended. Moreover, people in their 70s, who have a high incidence of serious and fatal cases after infection with the new coronavirus, are the key population requiring vaccine protection, and vaccination with the new coronavirus is recommended. It needs to be considered that the elderly population suffering from more underlying diseases, especially serious chronic diseases that cannot be controlled are contraindicated groups for New Crown vaccination, and some elderly people with low immunity, such as those with nephrotic syndrome and those suffering from malignant tumors, lack relevant safety data and should be carefully evaluated before choosing whether to vaccinate themselves. In addition, people over 70 years old who are allergic to any of the active ingredients or additives of the vaccine should not be vaccinated, and people who have had severe allergies during previous vaccinations, such as respiratory edema, inability to breathe, or angioneurotic edema coma, should not be vaccinated with the new crown vaccine. People over 70 years of age who are in the midst of an acute disease episode such as an infected fever are not eligible for New Crown vaccination.
