Cientistas da Universidade de Oxford, na Inglaterra, apontam em um novo estudo que a prote\u00e7\u00e3o gerada contra a variante Delta (B.1.617.2) do coronav\u00edrus pelas vacinas da Pfizer\/BioNtech e da AstraZeneca enfraquece em tr\u00eas meses. As conclus\u00f5es ainda n\u00e3o foram publicadas nem revisadas por pares, segundo a ag\u00eancia de not\u00edcias Reuters.<\/p>\n

O estudo se baseia em quase 3 milh\u00f5es de coletas de secre\u00e7\u00e3o de nariz e garganta realizadas na Gr\u00e3-Bretanha, em um total de 380 mil adultos, entre 1\u00ba de dezembro de 2020 a 16 de maio de 2021. A ideia era contrastar os per\u00edodos antes e depois que a Delta se tornou prevalente no pa\u00eds.<\/p>\n
