"All I know is that if I was given covid in the midst of winter in a poorly heated house (Hi U.K.) versus being given covid on the beach in south of France in May (not too hot, I’m still British), then I know which would result in a better outcome!"
That's interesting as on Sunday The Telegraph had an article saying that Dr Raghib Ali, a senior clinical research associate at Cambridge university's MRC Epidemiology Unit, " said Britain's relatively late lockdown meant more people were infected in the spring, when underlying pressure on the NHS was relatively light, meaning they were protected by antibodies come winter – when the service traditionally struggles to cope.
"Writing for The Telegraph, he that said that, in the absence of a vaccine, lockdowns postpone infections rather than prevent them, suggesting that March and April was a better period in which to catch the virus.
"[he] now argues that countries that locked down early effectively delayed part of their first wave until the winter, resulting in higher overall mortality."
Article here but it's behind a paywall.
I know it's not the same as your argument, but the two factors together: warmer weather (being outside more, higher vitamin D, feeling better) and a less-busy NHS, make me feel instinctively that I'd rather catch Covid (if I must) in the late spring/summer than late autumn winter.
