Shenzhen Kangtai New Crown Vaccine has been approved for vaccination in China, and is now being used on a large scale in Guangdong and other places. Shenzhen Kangtai New Crown Vaccine is a New Crown vaccine developed by Kangtai, which technically belongs to the inactivated vaccine, i.e., the vaccine made from inactivated New Crown Virus, which is a relatively mature type of vaccine. This type of vaccine is already relatively mature. At present, this vaccine has been approved for vaccination in China, indicating that its protective effect against the new coronavirus has reached the corresponding national standards. It should be noted that at this stage, the relevant authorities have only approved the homologous booster immunization of the inactivated vaccine against the new coronavirus from Shenzhen Kangtai Biologicals. That is to say, the people who have been vaccinated with Kangtai’s vaccine are different from those who have been vaccinated with other inactivated vaccines in that they need to receive homologous vaccination, i.e., they need to receive the booster vaccine of Kangtai’s New Coronavirus vaccine, and they cannot be vaccinated with other kinds of vaccines.
