IIRC it is around 50% effective? Hope the covid vaccine is better or we are in big trouble.
Why are we in big trouble if that’s the case? 50% effective, coupled with good medicine and testing should mean the world goes back to almost exactly where we were until now, with maybe a few more deaths each year.
Also, the flu vaccine is less effective because it mutates faster than corona, and many people don’t take it. I think at least in the short erm more people will be getting vaccinated for corona than were for flu.
