Vaccine Works In One Dose, No Longer Needs Ultra-Cold Storage

New stability data come as Israel study shows efficacy of single dose

FINANCIAL TIMES – The BioNTech/Pfizer Covid-19 vaccine no longer needs to be kept at ultra-low temperatures colder than the Antarctic winter, according to new results that will allow distribution to be dramatically expanded to doctors’ clinics, pharmacies and more remote regions.

Stability data, which the companies have submitted to the US regulator, show the shot can be kept at normal medical freezer temperatures of minus 15C to minus 25C for up to two weeks, compared with the previous required storage conditions of between minus 60C and minus 80C … 

BioNTech/Pfizer’s breakthrough vaccine was the first to win regulatory approval in the UK, US and EU last year, but the need to store and transport the shot below minus 60C has complicated the rollout, particularly in remote areas without “cold-chain” infrastructure.

‘Home Grown’ Coronavirus Mutation Found In NYC

Viruses mutate all the time. The more people who are infected, and the longer they are infected, the more chance the viruses have to change. A patient's body will be loaded with billions of copies of a virus, and may will be slightly changed, or mutated. Most will come and go. But sometimes a mutation or pattern of mutations takes hold and gets passed along.
