What Are the Odds That Novavax's Coronavirus Vaccine Is 90% Effective?
Last week, Pfizer (NYSE: PFE) and BioNTech (NASDAQ: BNTX) announced positive results from the phase 3 trial for their coronavirus vaccine. The drug, BNT162b2, met all of the study's primary and secondary endpoints, with an incredible 95% efficacy rate. Out of a subset of 8,000 volunteers, 162 people in the placebo group contracted COVID-19, and only eight people in the vaccinated group did.
Not to be outdone, Moderna (NASDAQ: MRNA) announced similar outstanding news. Ninety people in the placebo group tested positive for COVID-19, and only five in the vaccinated group. And finally, the vaccine named after the Russian satellite that was first in space -- Sputnik -- recently reported 92% efficacy.
