Cuba said on Monday its three-shot Abdala vaccine against the coronavirus had proved 92.28% effective in last-stage clinical trials.
The announcement came just days after the government said another homegrown vaccine, Soberana 2, had proved 62% effective with just two of its three doses.
“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.
The World Health Organization has set a 50-percent efficacy threshold for coronavirus vaccines to offer protection against the virus or disease.
Cuba has been relatively unscathed by the outbreak but has seen a recent sharp increase in cases, registering one of its worst days Monday with 1,561 confirmed infections in 24 hours. To date, it has recorded just over 169,000 cases and 1,170 deaths.
Under American sanctions, Cuba has a long tradition of making its own vaccines, dating back to the 1980s.
Nearly 80 percent of its vaccines are produced locally and it hopes to come up with the first locally-produced coronavirus shot in Latin America.
