(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: Baltimore Teacher Receives $25K To Buy New Equipment For Her Photography & Visual Arts Students
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: 'This Is 10K People Who Have Died' Maryland Woman Shares Story After Mom Dies From COVID-19, Urges People To Get Vaccinated
