The findings indicate protection will last even longer than six months, vaccine experts said.
“The information coming from Pfizer-BioNTech is good news with evidence that those enrolled in the clinical trials last year are still protected. So we know that immunity will not be short-lived,” Dr. Peter Hotez, a vaccine expert and dean of the school of tropical medicine at Baylor College of Medicine, told CNN.
“Hopefully the protection might last years, but we won’t know until we know.”
Par ailleurs il est dit qu’en Afrique du Sud le #vaccin est « 100% efficace » mais le nombre de participants, 800, est trop limité pour être aussi affirmatif :
“In South Africa, where the #B.1.351 lineage is prevalent and 800 participants were enrolled, nine cases of COVID-19 were observed, all in the placebo group, indicating vaccine efficacy of 100%,” the company said.
