Vaccine race speeding to the finish

The race between Pfizer and Moderna to bring a COVID-19 vaccine to use is getting tighter, according to a report from the Associated Press.

Earlier this week, Moderna announced that the results of its vaccine are showing 94.5% effective rates and now Pfizer has announced plans to seek emergency FDA approval for its vaccine that the company reports is 95% effective. Preliminary results from the Pfizer vaccine showed it to be lagging behind Moderna’s at 90% effectiveness. The new test results, however, are showing improved effectiveness and that it is safe and protects older people most at risk of dying, which is the last data needed to seek emergency use of limited shot supplies.

Pfizer is preparing within days to formally ask U.S. regulators to allow emergency use of the vaccine.
