I was quite surprised to read the article and hope this is a turning point to admitting naturally-gained immunity is actually a useful thing! Up till now it's been pretty much dismissed in this country.
I think you've misunderstood the science there. Or lept to this end of the current research and not appreciated the steps taken to gain data.
Covid remains a novel virus. No assumptions have stood without having been tested over time. As more data has been gathered understanding has been updated.
All done in real time with varying levels of certainty, validity etc.
Some have seen that as indecisive, fuckwitted or have concocted some odd conspiracy, assumed we are being drip fed for some reason of control far beyond that of pandemic management.
Others have watched and waited for the weight of data to manufacture some reliability in data before making comment.
Mostly though people have, over 18 months, become more expert than actual experts with 18+ years education and experience in specific scientific areas.
