In reply to CantClimbTom:
Good to read thank you. There was a lack of testing at the start of the pandemic so many people would not be classed as a possible reinfection in this study (understandably). Control measures and vaccinations would also stifle reinfections. Also, you might reasonably expect reinfection to be more likely over time (that study is from May 2021). My anecdata is reinfection 14 months (edit: sorry, actually 16 months) apart...not sure anybody was officially tested for covid 16 months prior to May 2021.
Edit: to add that Delta was only starting to become dominant in the UK following the study. My anecdata was Mar 2020 variant with reinfection of Delta late July 2021. Would be interesting to see further more up to date studies.
Honestly, I'm not a negative person and I'm pleased to read that article, just cautious about headlines from studies without all the context.
