Why Pfizer, BioNTech, Moderna, and Novavax Stocks Are Falling Today

This isn't shaping up to be a good week for the stocks of leading COVID-19 vaccine makers. Several of the stocks slipped on Monday. The downtrend continued today.

Shares of Pfizer (NYSE: PFE) were down 1.6% at 11:27 a.m. BioNTech (NASDAQ: BNTX) stock had fallen 9.4%. Moderna's (NASDAQ: MRNA) shares were 6.2% lower. Novavax (NASDAQ: NVAX) was an especially big loser, its shares having sunk 11.6%.

The declines for these vaccine stocks came despite some good news for several of them. Pfizer and BioNTech submitted initial data to the U.S. Food and Drug Administration from a late-stage study of their COVID-19 vaccine in children younger than 12 years down to age 5. Indian regulators also allowed the Serum Institute of India to begin enrolling kids ages 7 to 11 in a clinical trial evaluating Novavax's COVID-19 vaccine.
