Unlike the ultra-cold temperature of minus 80 degrees Celsius required for the $PFE $BNTX #COVID19 vaccine, the $MRNA product can be shipped and stored at the standard freezer temperature, making it easier to be transported to small and more rural areas, Gen. Gustave Perna noted.

As of midday Dec. 20, about 2.84 million doses of the Pfizer-BioNTech COVID-19 vaccine had been distributed and 556,208 doses had been administered, the U.S. Centers for Disease Control and Prevention reported.

Gen. Gus Perna said he was solely to blame for the miscommunication that led to last week's allocations of $PFE #COVID19 vaccine initially forecast to states to be significantly cut, while the company said it had millions of doses sitting in its warehouse waiting to be shipped.

The initial #COVID19 vaccine allocation plans were mistakenly based only on the number of doses produced but not yet "releasable" by the FDA, Perna said.

"It looked very good on paper," he told reporters. "It was my fault."
