It is not true that 23-valent pneumonia vaccine is not recommended. The 23-valent pneumonia vaccine is a self-funded vaccine in China, which has the effect of preventing diseases caused by pneumococcal infections, and individuals are vaccinated voluntarily, and there is no such thing as not recommending the 23-valent pneumonia vaccine. According to the Guidelines for the Diagnosis and Treatment of Community-Acquired Pneumonia, pneumococcal vaccination is recommended for people over 2 years of age who are at high risk of pneumococcal infection. Therefore, it is somewhat necessary for people over 2 years of age to receive the 23-valent pneumonia vaccine. However, 23-valent pneumonia vaccine is not recommended for infants and children under 2 years of age because the immune system of these people is not yet fully developed, and the vaccine will not produce a good immune response, and naturally will not be able to exert a good preventive effect. All in all, the 23-valent pneumonia vaccine is necessary to help prevent most pneumococcal infections and effectively maintain personal health. Especially for immunocompromised people over 2 years of age, 23-valent pneumonia vaccination is of great significance and importance.
