The Cuban scientist Amílcar Pérez Riverol held that the decline of Covid-19 in Cuba it cannot be attributed exclusively to Cuban vaccines, as the authorities have proclaimed, including the ruler Miguel Díaz-Canel himself.
“Just as it is incorrect to state that Cuban vaccines for Covid-19 are useless, it is wrong to associate the drop in daily cases in Cuba exclusively with vaccination, discarding the effect of infection immunity that — sadly— had / has a significant contribution, “said the biologist in a Facebook post.
Pérez Riverol, a Cuban graduate with a doctorate in Biological Sciences (Cellular and Molecular Biology) from the University of the State of Sao Paulo, in Brazil, shared a graphic that shows how “several countries that went through recent (and huge) waves of cases, caused for the Delta variant, they began the ‘sustained’ decline when vaccination coverage was still low. “
He clarified that this responds to “here it is also the effect of dangerous infection immunity“.
Recently, Miguel Diaz-Canel attributed to Cuban vaccines the “salvation of the country”, at a meeting of the Council of Ministers in which he spoke of official Covid-19 forecasts that have been fulfilled. The new cases would drop below 1,000 and on Saturday they reached less than 700.
“Our scientists with their vaccines – without being exaggerated – have contributed to saving the country. The result that the immunization campaign is having and the effectiveness of the vaccines is evident, which began to be applied in very difficult conditions, with a high circulation of the Delta strain, “said the first secretary of the Central Committee of the Communist Party of Cuba.
“The vaccination in Cuba occurred alongside one of the largest waves of cases / 100k in the world at the time. So that, this decline is the result of vaccination plus the costly effect of infection immunity, evidenced in all the countries that suffered outbreaks caused by the Delta, and that yes, it would have been much higher without the arrival of vaccines“said Pérez Riverol.
More than 7,100,000 people out of a population of 11,200,000 that inhabit the island have received the three doses of the Cuban vaccines Abdala, Soberana 02 and Soberana Plus against Covid-19, according to the latest data provided by the authorities.
The Pan American Health Organization (PAHO) has warned that vaccines against the coronavirus developed in Cuba they are not endorsed by the World Health Organization (WHO).
According to the Cuban authorities the Abdala and Soberana 02 vaccines have an efficiency of 92.2% and 91.2% respectively. The information and clinical trials of these drugs have not been shared with international organizations.
Nicaragua, Iran, Venezuela and Vietnam they have already acquired doses of the drugs to immunize their population. For now, it has not been revealed how much those countries have paid for the island’s products.
