The beta is advancing, and it’s worse than the delta: it already “escapes” the effect of two vaccines and causes the third wave in a key country

It should be mentioned that a report from the PAIS project, the consortium of researchers established by the Ministry of Science, Technology and Innovation to monitor variants of SARS-CoV-2 and study its evolution in Argentina, confirmed a few days ago the Delta variant has been detected in at least “59 countries, including Brazil and Argentina in Latin America”.

Likewise, in radio statements, the director of migration, Florencia Carignano, ratified last week that two cases of coronavirus of the aforementioned variant have been detected in Argentina, one of the “worrying” according to the World Health Organization (WHO).
