It works, but has inferior efficacy compared to mRNA vaccines. Same for J&J. If you have a choice, why get AZ? More over second shot is 3 months away, for mRNA it is at most 42 days away. J&J has one shot, that has efficacy lower event than AZ. US is vaccinated mostly using mRNA (because AZ took long to approve and J&J came at that time, but is now blocked). In my country we have the most amount of Pfizer vaccine, AZ screwed us and didn't deliver so why bother with almost non-existent vaccine that has lower efficacy? J&J delivered todays some vaccines, but I assume it won't do it anymore as it waits to see what happens with clothing.
