Drinking tea does not protect against pneumonia; there is no relationship between drinking tea and pneumonia. The ways to prevent pneumonia are daily prevention and vaccination. 1. Daily prevention: Strengthen physical exercise to improve physical fitness and immunity. Avoid smoking and minimize second-hand smoke. Avoid areas where people congregate to minimize exposure to the flu virus during the high flu season. Consume some protein and fiber-rich foods to improve your immunity. Wear a mask to prevent the spread of and contact with the virus. 2. Vaccination: The 23-valent pneumococcal polysaccharide vaccine can greatly reduce the rate of pneumococcal infection and death. The influenza virus can also be prevented by the flu vaccination, which is given roughly every year during the flu season, and immunity lasts for one year. A combination of the two vaccines can provide better immunization.
