In layman’s terms, that is, to a stream cracking strain of the virus inactivation, only retained the antigen to produce an effective antibody composition, neither people contracted the disease after inoculation, but also can promote an effective human antibodies against viruses. Cracking vaccine is a relatively good safety performance of the vaccine a vaccine that is currently used in China in the world and the most common seasonal influenza vaccine most of them are cracking vaccine.
Chen Chao said that even if vaccinated individuals had a risk of a flow of current vaccine is also a coupling cases, patients already infected with vaccine virus A stream is just not found during the incubation period only, that is, people often call a “coincidence” a. Such patients, even without vaccination will be disease. Chen Chao said coupling case not only in the vaccinated A stream will appear in the vaccine, vaccination, like other vaccines also have this phenomenon.
