There was a lot of focus on Beta because based on lab testing it was believed to have a greater risk of vaccine escape. In the end, Delta is usurping them all.
But anyway...
"Pfizer and BioNTech ... are developing an updated version of the Pfizer-BioNTech COVID-19 vaccine that targets the full spike protein of the Delta variant. 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."
