While Singapore starts clinical trials for its Covid-19 vaccine this week, there are other trials going on around the world.
Sinovac Biotech has a vaccine called CoronaVac that has already completed 2 out of 3 phases of clinical trials. 743 healthy people (ages 18-59) had been injected with the vaccine and there have been no side-effects.
AstraZeneca is also conducting trials for their vaccine co-developed with the University of Oxford. Concurrently, Moderna is also working with Cambridge for trials using another vaccine.
We certainly hope all these initiatives will turn out well and that mass vaccination using an approved vaccine can happen soon.
