Cuba has said its three-shot Abdala vaccine against the coronavirus had proved 92.28 per cent effective in last-stage clinical trials.

The announcement came just days after the government said another homegrown vaccine, Soberana 2, had proved 62pc effective with just two of its three doses, Reuters reports.

“Hit by the pandemic, our scientists at the Finlay Institute and Center for Genetic Engineering and Biotechnology have risen above all the obstacles and given us two very effective vaccines,” President Miguel Diaz-Canel tweeted.

Cuba, whose biotech sector has exported vaccines for decades, has five coronavirus vaccine candidates.
