It looks as if vaccines work well in controlling the spread of Covid-19.
These data are from the Financial Times, showing new cases/100K. The huge drop in the UK and Israel, combined with the sizable drop in the US and combined with the recent rise in Canada and Sweden is good prima facie evidence (not compelling for the skeptics, I know) about the importance of vaccines in controlling the spread of Covid-19.
Compare those case numbers with vaccination rates. The countries with low vaccination rates are reporting much higher infection rates. I know, correlation is not causation, but these data make a compelling prima facie case.
The current rise in rates in our area likely has more to do with poor ventilation and the hubris of youth [note that in London-Middlesex, well over 2/3 of the cases involving new variants are for people aged 0-29, and, of course, it's these younger people who are not receiving the vaccine yet.
