Elderly people aged 70 to 80 can receive the new coronavirus vaccine, provided that their underlying diseases, such as hypertension and chronic obstructive pulmonary disease, are well controlled and they are not in acute exacerbation. Neocoronavirus vaccination can prevent neocoronavirus infection and avoid the occurrence of neocoronavirus pneumonia, which has a protective effect on the human body. The new coronavirus vaccine is a vaccine against the new coronavirus. Elderly people between the ages of 70 and 80 years old can be vaccinated if they are relatively healthy, do not have any chronic diseases, or if their underlying diseases are well controlled and there are no contraindications to vaccination. However, if the underlying disease such as high blood pressure or heart disease is not under effective control, this new coronavirus vaccine cannot be given at this time. If you have chronic obstructive pulmonary disease (COPD), acute infections, or diabetes with acute infections, you should not be vaccinated at this time either. Vaccination with the new coronary vaccine can activate the body’s immune system, promote the body to produce specific antibodies against the new coronary virus, and form the corresponding immune memory, so that when the body is re-infected with the new coronary virus, the immune memory cells can respond quickly. Patients with a history of severe vaccine allergy, patients with severe uncontrolled chronic diseases, patients with acute exacerbation of chronic diseases, and patients with fever are prohibited from receiving the new coronavirus vaccine. Elderly people aged 70~80 years old who need to receive the vaccine should consult the physician at the vaccination center for advice and observe whether there are any adverse reactions after vaccination. Tip: The terms “new coronavirus pneumonia” and “new coronavirus pneumonia” mentioned in this article were renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
