According to the Director of Biomedical Research at the Center for Genetic Engineering and Biotechnology (CIGB) Gerardo Guillén, the shocking toll of Covid-19 infections in the last period – in Cuba and globally – is associated with a superiority of Delta variant, first identified in India.

This new variant is capable of colonizing the nasopharyngeal mucosa with a greater quantity of viral particles, both in those people vaccinated and those who are not, said Guillén.

Guillen further explained that an advantage for vaccinated people is the swift disappearance of the virulent load in relation to unvaccinated people, as well as the reduction of the risk of serious conditions and death.

In his speech, Guillen said that all vaccines created to date have proved a greater neutralizing capacity against Delta variant, compared to Beta variant already reported in South Africa.
