I have noticed that world wide figures for new infections have come down. The death rate is following. They are saying it is because of the vaccine.
I don't think the vaccine is having much effect except in Israel, UK maybe, US maybe. The infection rates in Canada are coming down as well, and hardly anyone has been vaccinated.
One of the early benefits of vaccinating health care workers is that they won't need to be self isolating if they are exposed to *********. One of the stresses in NB was that we might have 100 or 200 health care workers self isolating at any given time (I think mostly in relation to outbreaks at nursing homes).
