Good observation...and the answer is NO. We have had quite a run on Covid, Flu and bronchitis here...and I have dodged the bullet so for, despite working with many who caught them.Question for you guys and gals: have you seen anyone get Covid 2x or more who has not gotten a vax? Everyone I know who has gotten it again has had a vax. Everyone else seems to have natural immunity. What has your experience been?
