Important clarification re. repeat #COVID19 infections
No doubt a repeat infection is worse than no repeat infection - EVERY time carries risk of bad outcome.
What is still debated is whether an infection makes bad outcome from future infection more or less likely. Brief🧵

The fact the second point is being debated should not distract you from the first. Even if you've been infected one or more times you should try to protect yourself from another.
Earlier, some thought 1 infection=absolute long term protection. Definitely wrong
Science not settled on whether 1 infection provides degree of overall protection or is in fact harmful, which there is increasing evidence to support
Key: protect yourself from next infection

As Dr Sharkawy points out here, there is evidence that serial vaccination is protective, but NOT serial infection

Like most things in the real world, I suspect that the answer is both "it depends" and "reduce transmission"
In a #lowcovid situation with slow viral evolution & long time btw infections prev infection may be somewhat protective
In current #highcovid situation w rapid viral evolution & immune evasion prev infection does not seem to be protective & may worsen chance of bad outcome
