That people who have also had natural infection are more as protected as those who got vaccinated, as now indicated by the CDC. I had eluded to the Israel study a few months back but was admonished for using it because it had not been peer reviewed yet. But now the CDC is showing similar data to those in Israel.
The vaccine did not work for me as I had a break through infection and got delta. Also I was not more than 6 months out from being fully vaccinated and still got delta as well.
