Warren Buffett Just Sold His Pfizer Stock. Why?

Buffett-led Berkshire Hathaway opened a position in Pfizer in the third quarter of 2020. In a regulatory filing last week, though, Berkshire revealed that it had dumped all of its shares in the big drugmaker..

Pfizer won emergency use authorization (EUA) for COVID-19 vaccine Comirnaty (BNT162b2) in the U.S. and in Europe. It lined up major supply deals for Comirnaty totaling in the hundreds of millions of doses. The company also reported good news for several of its pipeline programs. All we can do is guess why Berkshire sold all of its Pfizer shares..

What (if at all) has gone wrong with this vaccine and or with Pfizer?

Last week:
Pfizer revises ultra-cold storage guidance for Covid-19 jab, says vaccine is stable at refrigerator temperatures


Vaccine partners Pfizer and BioNTech have said they’ve submitted new data to the US health regulator showing their jab can be stored at “refrigerator temperatures” rather than the ultra-cold levels currently mandated.

In a statement on Friday, the pair claim that their jointly developed Covid-19 vaccine can actually be stored safely between -25ºC and -15ºC – a substantial change from the -80ºC and -60ºC temperatures previously thought necessary.

The companies said they have shared their new data with the US Food and Drug Administration (FDA). “If approved, this new storage option would offer pharmacies and vaccination centers greater flexibility in how they manage their vaccine supply,” said Albert Bourla, chairman and CEO of Pfizer.

Under current guidance, the Pfizer-BioNTech vaccine must be stored at ultra-cold temperatures, and the extreme requirement has impacted the jab’s usage in many countries around the world, as the necessary cold-chain capability is not universally available.

In early November, Pfizer’s jab became the first Covid-19 vaccine candidate to release its complete phase three trial data. The shot is now widely used around the world.

The company has vowed to help deliver doses to poorer nations, but UNICEF has warned that many countries face challenges storing the solution at such ultra-cold temperatures and quickly administering the shots once they arrive.

So…..how has the basic nature of RNA changed?

Here’s why COVID-19 vaccines like Pfizer’s need to be kept so cold
Freezing RNA-based vaccines keeps their fragile components from breaking down

“Many RNAs are quickly degraded once read. Quickly disposing of RNA is one way to control how much of a particular protein is made. There are a host of enzymes dedicated to RNA’s destruction floating around inside cells and nearly everywhere else. Sticking RNA-based vaccines in the blast freezer prevents such enzymes from tearing apart the RNA and rendering the vaccine inert.”
