Cuba will supply large quantities of its home-grown Covid-19 vaccine, Abdala, to Vietnam and also transfer the production technology to the Southeast Asian country by the end of the year, Reuters quoted the Vietnamese health ministry as saying.

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

The Southeast Asian country has secured more than 23 million doses of Covid-19 vaccines and expects to receive at least 50m doses in the fourth quarter, the health ministry said.
