neb: That's the J&J, the least effective of the vaccines?
And still had 100% efficacy against hospitalization and deaths in their clinical trials.
All the western approved vaccines are extremely effective against serious harm.
Exactly - and while the efficacy levels weren't as great as some others such as Pfizer and AZ after two doses, they delivered better protection after a single dose. At the start of the year they started trials of a two dose "booster" of the Ja&J/Janssen vaccine that does seem to be delivering pretty good results.
In many poorer countries a single dose vaccine that has pretty basic storage requirements and offers pretty good protection has plenty of potential.
There will be a number of people here receiving this jab who would currently be deemed too high risk for the Pfizer.
