Brief Summary
COVID-19 is a novel coronavirus infection caused by respiratory droplets and contact transmission. With the spread of the epidemic, it has become a serious threat to global public health. China has launched a full range of vaccination including the third dose of homologous and sequential booster immunization. To further improve COVID-19 vaccine immunization strategy, we start the clinic research about sequential Immunization With Recombinant Adenovirus Type-5-vectored COVID-19 Vaccine in Health Adults Based on 3 Doses Inactivated COVID-19 Vaccine in Zhejiang province.
