I was talking with one of my friends in Spain and he told me that the hope there is that half the population of Spain will be vaccinated by May.Likely be sooner than that once the j&j trial finishes in early 2021. It is single dose and would help immensely. Basically, the more pipelines, the quicker it will be.
I agree with that the more vaccines that work well and are approved the sooner more people can be vaccinated.
Currently we have Pfizer already applying for EUA, Moderna should be next, and AstraZenica should be applying by the end of this year. Then J&J hopefully in January.
