In August, Pfizer plans to ask the Food and Drug Administration for emergency authorization of a third dose, he said. Why might that matter for fighting the delta variant? Dolsten pointed to data from Britain and Israel showing the Pfizer vaccine “neutralizes the delta variant very well." But a single vaccine dose dramatically boosted their antibody levels — sparking cross-protection against the delta variant and two other mutants, the study found. Researchers in Britain found two doses of the Pfizer vaccine, for example, are 96% protective against hospitalization with the delta variant and 88% effective against symptomatic infection.
