Thank you for this! Do you have any insight into how it might play out for people who had natural infection with the original strain but no vaccination?

I believe I have had Wuhan strain (March 2020), Delta (August 2021), and Omicron (December 2021). I've had no covid vaccinations, but the illness was milder each time and virtually asymptomatic with Omicron. I am 50 and very healthy overall. Is natural immunity any better at coping with OAS?
