Data re seriousness of reinfections

[Florelei]

Hello, I’m looking for data as to whether a subsequent covid infection is less severe than the first.

Does anyone have any information on this point please? I’d really appreciate any help anyone can give in pointing me in the right direction please.

Thanks in advance.

The three people I know who've had it twice have been floored by it the second time, after having barely any symptoms the first.

Although I appreciate that's a pretty useless, negligible sample.
