Lo que comenzó como un rumor y se transformó en una posibilidad, cada vez está más cerca de ser una certeza cuyo impacto en los planes de vacunación contra el Covid-19 es todavía imprevisible.
El cofundador de la farmacéutica alemana BioNTech, el doctor Ugur Sahin, confirmó que la vacuna contra el coronavirus desarrollada por su laboratorio y distribuida junto a su socio estadounidense Pfizer necesitará una tercera dosis 9 meses después de la aplicación de la segunda, que se administra a los 21 días de la primera inoculación, para mantener su eficacia.
“You have resumed negotiations with Pfizer to also hear that this is the situation in which safe adjustments can be generated to move forward with a contract,” Cecilia Nicolini, presidential adviser, explained this week in statements to Futurock. Array radio
In 2020, the laboratory carried out clinical trials at the Military Hospital, in combination with BioNTech, to verify the effectiveness of its mandatory activity. that the last year will be definitive.
Por eso, el presidente Alberto Fernández salió a denunciar que el laboratorio estadounidense había impuesto “demasiadas exigencias” que otros proveedores de vacunas “no han tenido”.
“Pfizer nos pidió una Ley de Vacunas, y nosotros cumplimos. Y ahora nos piden otra ley para evitar responsabilidades penales si las vacunas causan daños físicos. Esa inmunidad jurídica no se la vamos a dar”, explicó en esa oportunidad.
The ‘certifications’ of the AstraZeneca government when starting the entry of vaccines
While there may be some other deadlock in negotiations between Pfizer and the Argentine government, Ugur Sahin, CEO of BioNTech, said: “Coverage will be lower over time. We have knowledge that indicates that 6 months ago coverage is not at the level of 95%, it is still at 91%. And 8 months ago we saw that antibodies obviously produced coverage for men,” he said.
And I affirm that “for that we want a 3rd dose to provide nine to one hundred percent protection. ” Furthermore, the maximum effectiveness of the vaccine, which is 97%, was not reached until 7 days after receiving the second dose, and I identified that within 6 months immunity began for the offspring. “
This means that between nine months and a year later, you will most likely want to get a third dose to reach this maximum level of protection. For this reason, he is confident that Pfizer “probably” will become an annual vaccination, like the existing problem.
Last year, Pfizer CEO Albert Bourla said a third backup dose was “likely” and at the time said “this all needs to be confirmed. “
The Pfizer/BioNTech alliance announced in February that it was studying the effects of a third dose of the vaccine, based on the evolution of more than 12,000 participants in a clinical trial.
