Oddly, we don't have a thread about this yet. (We do now.) There are now numerous candidates for vaccines, despite the gloomy projections made at the start of the pandemic as to the likelihood of developing a successful one. As far as I can see, all are still in the testing stages, but have been given to plenty of people and five or six seem to be close to the end of the testing phase because regulators aim to speed up the processes involved in approving them.
The first one we heard about was the BioNTech/Pfizer vaccine, followed more recently by the Moderna vaccine and the 'Oxford vaccine' by Oxford University and AstraZeneca. Russia claims that its own homegrown one is better than all of those. Inevitably, all these claims still need to mature somewhat, as some of the announcements are probably designed to steal a commercial march on rivals.
These are the main ones I've seen information about, but I'm sure there are numerous others--I think there were about 100 or more in development at one point?
I've read that the 'Oxford vaccine' is meant to be not-for-profit or no-profit and much cheaper than the BioNTech and Moderna vaccines.
The only other distinguishing characteristic I've seen is that the BioNTech vaccine needs to be stored at -70 degrees Celsius, whereas the others can be kept at 2-8 degrees, e.g. as in a standard fridge.
Anyway, let's hope that the various claims of efficacy made so far survive into the real world and that by next year the disease is under much better control.
It would still be much better not to let a disease like this escape from the area in which is originates, but beggars can't be choosers, and a vaccine will be necessary.
