Why Shares of Pfizer Are Rising Today
Pfizer (NYSE: PFE) was up 1.6% late this morning after the company -- along with partner BioNTech (NASDAQ: BNTX) -- indicated it will begin seeking authorization for a COVID vaccine booster next month. The push is on as the Delta variant becomes the dominant strain of the virus in more regions.

Although both companies have indicated the boosters would be needed, it's the first official move toward making the extra jabs a reality. The pair cited a statement from Israel's health ministry claiming the vaccine's efficacy declined six months after vaccination. That contradicts findings in the U.K., where officials said the Pfizer-BioNTech vaccine was 88% effective at preventing symptomatic infection from the Delta variant of the SARS-CoV-2 virus.
