I am one of those considered extremely vulnerable, and had the first three vaccine shots, before reading more about it and decided to take my chances. I have never had covid as far as I am aware (7 negative hospital tests), could have had it asymptomatically I guess. I was also very blase about masks and the two metre rule.
It was interesting to note that absolutely nothing was mentioned on the msm about T cells, leaving joe public to believe everyone was at danger of catching the deadly virus. Maybe they could have tested everyone to see who had T cells, thus allowing them to go about their daily business.
