The current vaccination strategy is based on a “two-step” program: the first step is to first vaccinate key populations, including those involved in imported cold chain logistics, isolation site staff, closed-loop management of inbound personnel, customs border control personnel, cross-border drivers and shuttle drivers of mainland nationality, medical and health personnel, grassroots epidemic prevention personnel, public transport workers and other workers at high risk of infection. Staff with higher risk of infection, such as public transportation workers, as well as those who go to medium and high-risk countries or regions for work or study. In the second step, as the vaccine is conditionally approved and marketed, and the production of the vaccine gradually increases, more vaccines will be put into use. Through orderly vaccination, all eligible people will be able to receive the vaccine as soon as possible. Content source: Dr. You Lai
