Easy: zero. My brother has it for the third time, boosted of course. His woman has had a nasty persistent cough for six weeks after her last Covid. Thankfully, their kids are unvaccinated and likely to stay that way. It's weird. Out of all my family, only the ones not mRNA-injected and those who are 75+ of age remains Covid-free. And the elders are boosted 3-4-5 times. Makes me think there's a cumulative or cascade or knock-on effect from all the other vaccines people think they need. Clean clothes, proper hygiene, as un-processed food as possible, clean water and 8 hours solid sleep every night works heaps better against almost all diseases - which most doctors and apothecaries and so on will agree on, if only in privaye. Weird. Edit: How's the foot healing?
