A number of COVID-19 vaccine companies are gaining ground, and Pfizer is one of them. However, the Pfizer vaccine requires extreme sub-zero cold storage.

Because of this, cold storage companies are becoming increasingly vital to public health. That means investors are focusing on the profitability of cold storage stocks.

Why does the Pfizer vaccine require cold storage?

The Pfizer vaccine requires refrigeration at minus 70 degrees Celsius. This is because it uses messenger RNA (or mRNA) as a basis. Plus, there are no preservatives within the vaccine.

Vaccines that use mRNA are a newer technology, and they can reportedly be produced at a faster rate than others. However, the need for cold storage could cause supply chain problems of its own, especially in underdeveloped nations.

Pfizer isnt the only company creating a vaccine that requires cold storage. Modernas is also cold-dependent. However, Modernas product only needs a temperature of minus 20 degrees to be kept stable. Moderna also takes the mRNA approach in their vaccine.

Whats in the Pfizer COVID-19 vaccine?

Aside from mRNA, the Pfizer COVID-19 vaccine contains four types of lipids, four types of salts, and sucrose. The lipids help encase (or protect) the mRNA as it makes its way into our cells. The salts help balance the vaccines pH level to mimic our natural physical acidity. Sucrose, or just plain sugar, works to keep particles from sticking together when frozen.

 Like most intravenous drugs, the vaccine is mixed with a saline solution prior to injection.
