The Pan American Health Organization (PAHO) says work is advanced on the development of a coronavirus (COVID-19) vaccine in Cuba

The Pan American Health Organization (PAHO) says work is advanced on the development of a coronavirus (COVID-19) vaccine in Cuba.

PAHO Assistant Director, Dr. Jarbas Barbosa, said information received indicates that the vaccine’s development will shortly enter the third and final stage of clinical trials.

He cautioned, however, that no timeline could be determined for the completion of the process, “as the [third] phase takes the longest.”

The Cuban vaccine producer joins several others, whose candidates are at various stages of development and analysis.

Among them are: the Moderna vaccine, which Dr. Barbosa indicated is in the final stages of analysis; the Sinopharm vaccine, for which the producer has requested evaluation; and the Johnson & Johnson vaccine which, he pointed out, is “also being assessed.”

The Pfizer vaccine and both AstraZeneca vaccines, which are produced in India and South Korea, are the candidates already approved by the World Health Organization (WHO).
