The protection offered and side effects of Russia's vaccine are unknown as clinical trials were not completed according to Taiwan's health minister and Central Epidemic Command Center (CECC) head Chen Shih-chung.
Chen said that "some important people even asked their relatives to set an example, it's quite brave," in a report from Taiwan News.
Chen specified that up until this date, none of the vaccines under development in the world have completed human clinical trials, "and there is no clear answer."
The health minister has doubts about the level of protection it can offer, and it will probably be a long while before it can be widely used.
On August 11, Russian President Vladimir Putin announced the approval of a coronavirus vaccine for use, claiming it as a "world first," amid continued concern and unanswered questions over its safety and effectiveness.
