Tokyo, June 28 (Jiji Press)–With more than 100 research projects underway to develop vaccines for the novel coronavirus, the United States, Europe and China have taken a lead in clinical trials, but a Japanese team also plans to start trials on Tuesday.
According to the World Health Organization, about 140 vaccines are being developed and 16 of them are in the stage of safety and efficacy confirmation in clinical trials.
In addition to conventional inactivated vaccines, a new type called gene-based vaccine is being developed.
A gene-based vaccine develops immunity by taking parts of DNR or RNA of a virus into the human body. As it does not involve the cultivation of a virus itself, the development of such vaccine features a shorter manufacturing period and lower costs.
Although no such vaccine has been put into practical use, it may be able to deal quickly with virus mutations.
