The Technical Guidelines for Vaccination against the New Coronavirus, published by the National Health and Wellness Commission, states that people aged 60 years and older are at high risk of serious illness and death after infection with the New Coronavirus, and that a large amount of trial data confirms that the New Coronavirus vaccine is also protective for people aged 60 years and older, so the National Health and Wellness Commission recommends that older people who are eligible for vaccination should be vaccinated as much as possible. However, elderly patients who are allergic to the vaccine components or who have had severe allergic reactions to the vaccine in the past should be strictly prohibited from receiving the vaccine. In addition, vaccination is not recommended for women during pregnancy, patients with severe neurological diseases, and patients with fever, acute illnesses, acute episodes of chronic diseases or serious uncontrolled chronic diseases. Since the proportion of elderly people suffering from chronic diseases is higher than other populations, it is necessary to test the blood pressure and blood sugar of elderly people before receiving the New Crown vaccine. Elderly people who meet the requirements should complete the vaccination in strict accordance with the vaccination process and actively cooperate with the state to establish a herd immunity barrier to reduce the risk of infection in the group as well as in individuals.
