The probability of this happening is very low. We have effective coronavirus vaccines for pigs (although not for COVID-19). For most viruses people recover from, they keep immunity and we don’t have good evidence that COVID-19 is different. While COVID-19 might do some harm to most people that recover, if the harm was on average significant we should have a lot more evidence of this. Also, the space of possible effective treatments is huge and it seems likely that within 2 years (perhaps even two months) we will be able to greatly improve outcomes for the infected. Finally, keep in mind that we have just started to fight COVID-19, and so we have not already tried and failed with all the obvious approaches and this should make us relatively optimistic about coming up with effective treatments or vaccines.
Coronavirus (and other viruses) causes severe disease in neonatal piglets. Vaccination of pregnant sows in order to confer “lactogenic immunity” i.e. antibodies in the milk is, as far as I’m aware, the main use of coronavirus vaccines in swine.
(I was a veterinary surgeon but I’ve not treated pigs in over a decade.)
