Covid-19 Argentina

Argentine infectologist questions Pfizer’s mRNA COVID-19 vaccine and highlights efficacy of Sputnik V

By · December 28, 2021 · 2 min read

RIO DE JANEIRO, BRAZIL – Argentine infectologist Gabriela Piovano highlighted in a radio program the efficacy of the Russian anti-COVID-19 vaccine Sputnik V and questioned the countries that do not approve it while criticizing the Pfizer vaccine, produced by the German laboratory BioNTech.

“The world that these people have proposed has no way out. You can see that the United States and Europe have deprived their citizens of a perfect vaccine without the Sputnik V vaccine. The worst vaccine is the Pfizer one because you have to keep it at -180 degrees and you also have to transport it, and you also have to give yourself a dose every three months, we all realize that it is the worst vaccine”, said the infectologist of the Muñiz hospital in Buenos Aires.

Asked about the increase in the number of positive cases on the HTH program of the local radio station Metro 95.1, she said: “What we are going to see are many cases and proportionally much fewer sick people. We are concerned about the small proportion of people who become seriously ill”.

Finally, she acknowledged that the primary concern in Argentina is the Delta variant, still in circulation.
