Investment bank Morgan Stanley projected that Pfizer's COVID-19 jab is expected to bring in $19 billion next year. Meanwhile, Goldman Sachs remarked that Moderna will rake in $13.2 billion in earnings come from its Wuhan coronavirus vaccine.

This comes in stark contrast to pharmaceutical firms Johnson & Johnson and AstraZeneca, who have vowed to offer their Wuhan coronavirus vaccines at no profit once they are approved for emergency use. The vaccine candidates from AstraZeneca and J&J are currently undergoing trials as of writing.

The messenger RNA (mRNA) vaccines from Pfizer and its German partner BioNTech and Moderna both reported more than 90 percent efficacy rates in clinical trials. However, the U.S. Food and Drug Administration (FDA) authorized the Pfizer/BioNTech jab for emergency use Dec. 11. A panel consisting of 23 independent scientists voted in favor of the BNT162b2 jab and recommended it to the FDA the day before, following long and drawn-out talks over its safety.
