On Wednesday, BioNTech and Pfizer announced that they have provided high levels of protection for Covid-19 with three doses each of their vaccine.

Preliminary lab research shows that a booster dose of vaccine can increase antibody protection by 25% compared to initial two-dose series. An additional shot can produce antibody levels similar to those in the initial two dose series. This is associated with high protection.

Albert Bourla, CEO of Pfizer and BioNTech stated that even though two doses may offer some protection from severe Omicron-related disease, the preliminary data suggest that protection can be improved by a third dose.

He stated that “Ensuring the maximum number of people are fully vaccinated using the two-dose series plus a booster is the best way to stop the spread of COVID-19.”

Two doses of vaccine were administered by the companies and showed significant decreases in antibodies’ ability to neutralize or target omicron.
