Zeng Guang: Vaccines must be changed for the fourth dose, and inactivated vaccines can no longer be used

On December 22, Zeng Guang, a well-known expert in public health and epidemiology, delivered a speech on the theme of “Causes and Countermeasures of this Wave of Epidemic Storm” at the Innovation Forum of the 2022 NetEase Future Conference. Zeng Guang pointed out that now we must speed up vaccination, especially for the elderly who have not been infected, for medical staff, and for those who have more contact with the public, we must take the lead in vaccinating. Regardless of whether it is a person who has received two or three injections before, he can start to receive the fourth injection. The vaccine must be changed for the fourth dose, and the inactivated vaccine can no longer be used. In addition, he also mentioned that from a national perspective, the epidemic will continue for two to three months, spanning New Year’s Day and Spring Festival, that is, when spring comes, the national epidemic situation will improve. | Related reading (Hangzhou Net)

In theory, Zeng Guangdian’s point of view may be correct. In the process of opening up in Hong Kong, relevant departments in Hong Kong also suggested that Hong Kong residents get mixed vaccines. However, the difference between the mainland and Hong Kong is that Hong Kong’s mixed vaccination is a mixture of mRNA vaccines and inactivated vaccines, which really helps to reduce the rate of severe illness. However, Zeng Guang suggested that inland residents should not take the inactivated vaccine for the fourth dose. Since there is no mRNA vaccine for inland residents, the implication is to suggest that everyone should be vaccinated with the inhaled adenovirus vaccine that has just been launched. Although this kind of mixing is better in theory, it is not easy to compare with Hong Kong’s infection and severe disease data, so there is still some uncertainty in the future effect.
