BRASILIA, Oct 19 (Reuters) - An experimental vaccine against
COVID-19 developed by China's Sinovac Biotech proved to
be safe after its two doses were applied to volunteers in
Brazil, according to preliminary results of a late stage
clinical trial by Sao Paulo's Butantan Institute.
The institute's director Dimas Covas said on Monday that
Coronavac was the safest of the vaccines being tested in Brazil,
though data on how effective it is in protecting people against
the new coronavirus is not ready yet.
