Rumor identification: Vaccines to prevent pneumonia do not protect against new coronavirus infections. Rumor analysis: 1. Pneumococcal vaccine and Haemophilus influenzae type B vaccine and other pneumonia vaccines mainly prevent pneumonia caused by pneumococcus, and do not prevent the new coronavirus pneumonia. Because the new coronavirus is more transmissible and different from the coronavirus that has been found in the past, it is necessary to develop a vaccine against this virus. 2, researchers are currently working to develop a vaccine against the new coronavirus, as of now, the development of inactivated vaccine is undergoing virus culture, recombinant genetic engineering vaccine development has completed the synthesis of gene sequences, now the vaccine has been tested in animals, but because of the effectiveness and safety, further research is needed to verify. Special Note: Not only has a clinically effective vaccine for the new coronavirus pneumonia not yet been developed, but there are no specific drugs for the treatment of the new coronavirus pneumonia, and only symptomatic supportive treatment is available, so good preventive measures are advocated to avoid infection as much as possible. For example, infection can be effectively prevented by actually isolating, wearing masks, washing hands regularly, going out less often, and disinfecting well.
