It stated it could search emergency use authorization from the US Meals and Drug Administration for a booster dose in August after releasing extra knowledge about how nicely a 3rd booster dose of vaccine works.
“As seen in real world data released from the Israel Ministry of Health, vaccine efficacy in preventing both infection and symptomatic disease has declined six months post-vaccination, although efficacy in preventing serious illnesses remains high,” the corporate stated in a press release emailed to CNN.
“Additionally, during this period the Delta variant is becoming the dominant variant in Israel as well as many other countries. These findings are consistent with an ongoing analysis from the Companies’ Phase 3 study,” it added.
“While protection against severe disease remained high across the full six months, a decline in efficacy against symptomatic disease over time and the continued emergence of variants are expected. Based on the totality of the data they have to date, Pfizer and BioNTech believe that a The third dose may be beneficial within 6 to 12 months following the second dose to maintain highest levels of protection.”
Israel’s well being ministry stated in a press release earlier this week that it had seen efficacy of Pfizer’s vaccine drop from greater than 90% to about 64% because the B.1.617.2 or Delta variant unfold.

“While Pfizer and BioNTech believe a third dose of BNT162b2 has the potential to preserve the highest levels of protective efficacy against all currently known variants including Delta, the companies are remaining vigilant and are developing an updated version of the Pfizer-BioNTech COVID-19 vaccine that targets the full spike protein of the Delta variant,” the corporate stated. Present vaccines goal only a piece of the spike protein — the a part of the virus it makes use of to connect to cells.
“The first batch of the mRNA for the trial has already been manufactured at BioNTech’s facility in Mainz, Germany. The companies anticipate the clinical studies to begin in August, subject to regulatory approvals.”
