My phone hasn’t been ringing as much in the last week. That’s good. We are still seeing sporadic cases but so far the surge of Omicron BA2 cases has not emerged. Most cases that I see are are diagnosed by home testing, which is not represented in these numbers. The BA2 strain is now 75% of Covid 19 cases in Texas. We are hopeful that people with immunity acquired by vaccine, illness or both will dampen the spread. We will see whether there is a Fiesta bounce. Yesterday the New England Journal published the latest analysis of Israel’s date on 4th vaccine doses. The bottom line is that a 4th vaccine dose helps to prevent severe infection. It also helps to prevent mild infection, but the effect is transient. It will be interesting to follow subsequent analyses over a longer period of time.
Here is the abstract portion of the article.
