Someone I know lined up to get jabbed and boosted in January/December 2021. He was still traumatized by his severe COVID-19 esperience in ... june 2020? In November '22 he said he's going to pass on getting bi-boosted, on account of not enjoying the adverse effects of getting boosted.
The silly thing is he probably had really good immunity from his actual case of COVID in '20. I don't think anyone claims that vaccine immunity > natural immunity anymore.
