Currently, there are many types of vaccines that can prevent respiratory infectious diseases, including influenza vaccines, chickenpox vaccines, and pneumococcal vaccines. We should scientifically choose vaccination according to the health status, age characteristics and risk of exposure of different groups of people, so as to achieve "classified policies, willing to plant as much as possible".

For children and adolescents, the immune system is not fully developed and is a high risk of respiratory diseases. In addition to completing the national immunization program vaccines, such as mumps vaccine, pertussis vaccine, and brain flu vaccine, it is recommended that children and adolescents over 6 months old be vaccinated against influenza every year, and children are also recommended to complete the vaccination of pneumococcal vaccine, Haemophilus influenzae type b vaccine, chickenpox vaccine and other vaccines according to the immunization procedure.

For adults, especially medical personnel, teachers, public service workers, and some people with underlying medical conditions, it is recommended to get the flu vaccine every year and the pneumococcal vaccine according to the health status. Some patients with chronic diseases, such as diabetes, chronic obstructive pulmonary disease, and cardiovascular disease, are prone to severe illness after being infected with respiratory disease pathogens, and vaccination should be prioritized.

For the elderly, due to weakened immunity and most of them with underlying diseases, they are susceptible to respiratory diseases such as influenza and pneumonia, and are prone to severe disease and even death after infection, it is recommended to get vaccinated against influenza every year, and pneumococcal vaccine is also recommended to reduce the risk of pneumonia and hospitalization.

Overall, vaccines are the most economical and effective measure to prevent respiratory infectious diseases. The public should take into account their personal health status and vaccination contraindications and receive relevant vaccines in a timely manner.
