Covid: How long does vaccine based immunity last?

It’s unfortunate that the drug companies decided to end their trials early, by giving active covid vaccine to the members of the placebo group after just a few months. It means that there is no long term follow-up of the covid vaccines from randomized trials, and there never will be. This means that we are instead forced to rely entirely on observational data as we … Read more

Covid-19 interview with Ben, Rob, and Robbo

A few days back I did an interview on the Ben, Rob and Robbo show about covid-19. In the interview we discuss what measures were taken in Sweden to prevent the spread of the disease, whether Sweden has now developed herd immunity, and what the role of T-cells vs antibodies is if that is the case.
