If recovered people have longer term protection than vaccinated people (which is one possible interpretation of the headline's statement), would it make sense to first vaccinate someone and then expose them to the real virus, thereby generating the benefits with a much much lower risk or maybe even zero risk?
Why? Make the patient catch Covid… so that they don’t later catch Covid?
And you will infect a lot fewer people, maybe zero, for the rest of your life, too. Should also help with avoiding future pandemics from this virus.
