For those interested, the fourth 'western' vaccine to be potentially authorized is the Johnson & Johnson viral vector (a la AstraZeneca or Sputnik V) vaccine. This one is potentially quite important as it is intended as a single shot product (though a large trial with two shots has also been initiated). The JJ vaccine uses the same vector as their Ebola vaccine. The company claims to be able to produce 1 billion doses this year, though anecdotal evidence suggests that production is lagging. Interim results from the phase III trial are expected end January/early February. According to a spokesman from the Warp speed (more like Walk speed) project (so not the company) the efficacy is around 80%. The EU is a big client for the JJ vaccine (400 million doses) whereas the COVAX project has an MoU for 500+ million doses..

In other news, the EU is expected to authorize (or not) the AstraZeneca vaccine on Jan 29th. Also ordered an additional 300 million doses of the Pfizer-BionTech vaccine.

1 shot seems like a better idea. I image quite a few people getting the 2 shot vaccines may just have 1 and never get around to having the 2nd shot.
