In recent studies done by Pfizer/BioNTech, the company says they have shown that a third shot of the Covid-19 vaccine can “strongly” boost protection against the Delta variant — adding extra protection to the standard two-dose application.
“Receiving a third dose more than six months after vaccination, when protection may be beginning to wane, was estimated to potentially boost the neutralizing antibody titers in participants in this study to up to 100 times higher post-dose three compared to pre-dose three,” Dolsten said. “These preliminary data are very encouraging as Delta continues to spread.”
