The Incident Manager at Pan American Health Organization (Opas), Sylvain Aldighieri, said this Wednesday that, given the advance of new variants of the coronavirus, a 90% vaccination coverage of the population to control virus transmission. During a press conference, he reasoned that scientists have yet to reach a consensus on the prerequisites for collective immunity in the covid-19 case.

Just like the World Health Organization (WHO), PAHO said that there is no evidence to support the need for a third dose of the immunizer against the coronavirus. Aldighieri considered, however, that this scenario could change in the coming months.
When asked about the lambda variant, initially identified in Peru, Aldighieri said that detection of the strain has been sporadic in Latin America. Also according to him, there is no concrete evidence that lambda is more contagious, like delta.
Specifically about delta, the Incident manager at PAHO said that more studies are needed to know the real impact on hospitalizations and the severity of the disease.
The entity’s director, Carissa Etienne, in turn, declared that more vaccines are needed “now” for Latin America and the Caribbean. The authority also urged countries in the region to increase immunization coverage of indigenous communities.
