Pfizer: New Covid Vaccine Was 90% Effective In Early Analysis

By Susie Madrak — November 9, 2020

If these numbers hold up, this is wonderful news. I just want to point out that this is more credible because Pfizer never took federal money to be part of Trump's Operation Warp Speed. Via Bloomberg:

The Covid-19 vaccine being developed by Pfizer Inc. and BioNTech SE prevented more than 90% of infections in a study of tens of thousands of volunteers, the most encouraging scientific advance so far in the battle against the coronavirus.

Eight months into the worst pandemic in a century, the preliminary results pave the way for the companies to seek an emergency-use authorization from regulators if further research shows the shot is also safe.

Pfizer shares extended gains in premarket trading, rising about 15%, with BioNTech American depositary receipts up about 22%. The news added more than $500 billion to the value of the MSCI All Country World Index.

Dr. Sanjay Gupta on the positive Pfizer vaccine news this morning: "It seems to work, and it seems to work fairly quickly." Need to wait for safety data, tho.

Gupta lays out a timetable for Pfizer emergency use application and when this might be rolled out.

This is hopeful. pic.twitter.com/eq9LciTl3A

If the vaccine is truly 90% effective we will need to vaccinate at least 80% of the US (260 million people) twice. (520 million inoculations). In our best years with influenza we administer about 160 million doses. This will be a massive undertaking. We’re up to the challenge.

Pfizer vaccine >90% effective. That's great! Will still be a logistical challenge as doses need to be kept at ultra cold temperatures. Unclear where people will receive shots (+ 2nd follow up shot 3 weeks later) & what role govt will play in distribution. https://t.co/jmDplFboHj

2. It is also a really promising sign for the multiple other #Covid19 vaccines coming up behind Pfizer, as this statement from @CEPIvaccines points out. They all target the same protein on the #SARSCoV2 virus. Looks like it is a solid approach. pic.twitter.com/AoSVK9KBHm
