Why These 3 Coronavirus Stocks Are Falling This Week
Shares of COVID-19 vaccine developers Moderna (NASDAQ: MRNA), BioNTech (NASDAQ: BNTX), and Pfizer (NYSE: PFE) have fallen this week after presentations to the Centers for Disease Control (CDC) revealed that requirements for cold storage of mRNA-based vaccines may limit their availability in the early days of distribution.
Representatives from Moderna and Pfizer presented to the CDC's Advisory Committee on Immunization Practices on August 26, describing the "cold chain" needed to distribute their vaccines, a capability that will need to be in place this year and may require specialized equipment. Both vaccines require shipment at freezing temperatures, but more extreme requirements for the vaccine being developed by Pfizer and BioNTech could limit administration of it to larger sites, such as hospitals.
