He disclosed at the conference that the city has recently introduced two types of COVID-19 vaccines, including a vaccine inhaled through the mouth and a recombinant fusion protein vaccine (CHO cell), providing a wider range of options for citizens to get vaccinated and strengthen protection. There are currently six kinds of COVID-19 vaccines available in Shenzhen. The inhaled vaccine is a recombinant COVID-19 vaccine (adenovirus type 5 vector) developed by Chinese vaccine maker CanSino Biologics, which already launched a one-shot adenovirus-based vaccine against COVID. It is the world’s first inhaled COVID-19 vaccine used for sequential booster immunization, a vaccination strategy that uses different types of vaccines for original and booster inoculations. The recombinant fusion protein vaccine is developed by Livzon Mabpharm Inc. in collaboration with the Institute of Biophysics, Chinese Academy of Sciences. It is the first of its kind in Guangdong Province.The two new vaccines will be used for booster shots, said Li Xiaoheng, deputy director of the Shenzhen Center for Disease Control and Prevention. According to Li, the three different types of COVID-19 vaccines currently on the market, including inactivated vaccine, adenovirus-vectored vaccine and recombinant protein vaccine, are all suitable for senior citizens over 60.
