(CNN) — A third dose of the Pfizer/BioNTech Covid-19 vaccine can “strongly” boost protection against the Delta variant — beyond the protection afforded by the standard two doses, suggests new data released by Pfizer on Wednesday.
The data posted online, which are expected to be discussed in a company earnings call on Wednesday morning, suggest that antibody levels against the Delta variant in people ages 18 to 55 who receive a third dose of vaccine are greater than five-fold than following a second dose.READ MORE: Owusu Leads No. 8 Maryland Women Past Purdue 86-71
Among people ages 65 to 85, the Pfizer data suggest that antibody levels against the Delta variant after receiving the third dose of vaccine are greater than 11-fold than following a second dose.
There’s an “estimated potential for up to 100-fold increase in Delta neutralization post-dose three compared to pre-dose three,” researchers wrote in the Pfizer data slides.READ MORE: Anonymous Donor Pledges to Match Donations Up To $1,000 To Help Replace Stolen Salvation Army Red Kettle
The data have not yet been peer-reviewed or published.
The data also show that antibody levels are much higher after the third dose than a second dose against the original coronavirus variant and the Beta variant, first identified in South Africa.MORE NEWS: ATM Stolen In Elkridge Smash And Grab; Stolen Van Used Was Found In Baltimore, Police Say
