Rapid Response:

Six million Cubans will be vaccinated by August

Dear Editor
At the end of August, it is expected that around six million Cubans have been vaccinated against COVID-19, based on a comprehensive strategy that advances by strata following regulatory protocols and that considers vulnerability and risk until reaching a coverage that guarantees sufficient immunity of the population against the virus.
In order to reach this figure, it is planned to start an intervention study with 120 thousand health workers from Guantánamo, Granma and Santiago de Cuba, which will have characteristics similar to the one currently being carried out in Havana, and which will include 150 thousand volunteers; Abdala and Soberana 02 will coincide for the first time at the same time, although not in the same territories. Also included at this time of intervention are around 490 thousand workers from the health system in the capital, Santiago de Cuba, Granma and Guantánamo, and from the Group of Biotechnology and Pharmaceutical Industries of Cuba (BioCubaFarma).
In unison, attention has been paid to productive support with the necessary doses of the strategy outlined and each decision is based on the guarantee of productive capacity. Progress on the issue of vaccine candidates will be progressive, but with very solid steps, safe at all times and with extreme respect for the Cuban people, aware of the challenge that this disease represents, just one year after its introduction in the country. The intervention study began in Havana as it is the center for the transmission of the disease in the country and from where it is expected to obtain the greatest amount of information from the results.
Kind Regards
