Pfizer gives update on vaccine booster strategy

Pfizer found positive results for booster doses. Pfizer-BioNTech to update COVID-19 vaccine.

Where: NY, and Mainz, Germany

The Facts

▪ On July 8th, Pfizer-BioNTech provided an update on their vaccine booster strategy – the companies reported favorable results in their ongoing clinical trial for the third (booster) dose of their BNT162b2 vaccine.

▪ The clinical data indicated that the booster dose provides 5-10x higher protection than just the two doses against the wild-type and Beta variants – authorities anticipate a similar boost in antibody titers against the Delta variant following the third dose.

▪ The Pfizer-BioNTech press release read, “The companies expect to publish more definitive data soon as well as in a peer-reviewed journal and plan to submit the data to the FDA, EMA and other regulatory authorities in the coming weeks.”

▪ The two companies believe that current scientific data indicates that a third booster dose within 6-12 months of complete vaccination may be helpful to sustain the desirably high levels of protection against COVID-19.

▪ The press release stated, “While protection against severe disease remained high across the full 6 months, a decline in efficacy against symptomatic disease over time and the continued emergence of variants are expected.”

▪ Pfizer-BioNTech also announced that they are currently developing a new mRNA COVID-19 vaccine that will target the whole surface spike protein of the COVID-19 Delta variant.

▪ The two companies expect to begin clinical trials for the new vaccine in August, pending approval by relevant regulatory bodies.
