"However, there are logistical challenges as the vaccine has to be kept in ultra-cold storage at below minus 80C."
Does anyone know how many of the other vaccine candidates have this limitation? It seems to me that a vaccine with easier logistics might still end up having a bigger impact overall, despite not being the first - although that of course needs to be combined with the ease of production too (I don't know how easy it is to mass produce these new RNA vaccines compared to more traditional ones).
- grumple 6y agoI know that several of the vaccine candidates require similarly cold storage for their entire distribution cycle until they are being used. Disclaimer: I work for big pharma.
- ByteJockey 6y agoHow long, exactly, are they good for once they warm up? I assume you aren't injecting people with something at -80C. How big of a window is there for injections?
- nicoburns 6y agoOther comments here are saying something between 24 hours and a week at standard refrigerator temperatures.
- ByteJockey 6y agoThanks for the summary, I must have missed that.

- ceejayoz 6y agoThat's not very pricey as healthcare costs go. I get Stelara injections every three months; one milliliter is $10k, and that can't be spread out across anyone else.
- t3rabytes 6y agoCOVID PCR tests waiting to be sent to a lab also need to be frozen.
- kristjankalm 6y agolow temp storage was also required for the ebola vaccine and yet it was successfully administered to more than quarter of a million people in equatorial Africa https://en.wikipedia.org/wiki/Kivu_Ebola_epidemic#Vaccination https://en.wikipedia.org/wiki/Kivu_Ebola_epidemic#Vaccinatio... should be quite doable
