Shares of BioNTech (NASDAQ: BNTX) were down nearly 7% today after two studies of more than 50,000 patients in the Mayo Clinic Health System showed rival Moderna's (NASDAQ: MRNA) vaccine might be more effective against the troublesome delta variant of the SARS-CoV-2 coronavirus.

The effectiveness of BioNTech's vaccine, developed with Pfizer (NYSE: PFE), was only 42% during July, according to the study, compared to 76% for Moderna. The numbers were calculated at a time that delta has become the dominant strain infecting Americans. A second study showed nursing home residents generated stronger immune responses after the Moderna vaccine than after BioNTech's.
