Sinovac: Brazil results show Chinese vaccine 50.4pc effective

A coronavirus vaccine developed by China's Sinovac has been found to be 50.4% effective in Brazilian clinical trials, according to the latest results released by researchers.

It shows the vaccine is significantly less effective than previous data suggested - barely over the 50% needed for regulatory approval.

The Chinese vaccine is one of two that the Brazilian government has lined up.

Brazil has been one of the countries worst affected by Covid-19.

Sinovac, a Beijing-based biopharmaceutical company, is behind CoronaVac, an inactivated vaccine. It works by using killed viral particles to expose the body's immune system to the virus without risking a serious disease response, BBC reported.

Several countries, including Indonesia, Turkey and Singapore, have placed orders for the vaccine.
