A Further Note

The post below on the Delta variant has gotten a lot of attention. It’s always important to make a simple point: This isn’t “oh noooeesss, the vaccines don’t work anymore!” All the data suggests they remain extremely effective at preventing serious illness – over 90%. By the standards of almost any other vaccine they remain highly effective against any infection at all. Recent peer reviewed measures of the Pfizer vaccine against the Delta variant suggest efficacy in the high 80s percentage range. This new data out of Israel says it’s in the mid-60s. If you’re vaccinated, especially with one of the mRNA vaccines, there’s no reason for you to worry. The issue is more at the society-wide level, trying to make sense of the various data points suggesting a non-trivial level of reduced vaccine efficacy and how that maps onto how society at large will be operating in the coming months and years.

At the risk of stating the obvious, if you don’t want to die of COVID or end up in a hospital struggling to breath and fearing for your life, get vaccinated. You’ll be covered.
