Those are big "ifs", and especially "catching Omicron is mutually exclusive with catching Delta or any other strain" seems a bit unlikely. Namely, if there's a mutated strain which is resistant to vaccines targeting the previous strain, then it also implies that it's likely that the immune response from one won't fit the other much, just as previously with different strains of flu allowing reinfection.
- rossdavidh 5y agoCould quite possibly be true, although the article presents very preliminary evidence that we do not have vaccine escape (or not complete, anyway).
- spurgu 5y agoI mean the vaccine doesn't prevent transmission/infection for Delta (or Alpha) either, it just makes the symptoms milder. Edit: For whomever downvoted, here you go: > Prior to the emergence of the delta variant, it was reported that the risk of symptomatic cases in household contacts of vaccinated cases was about 50% lower than that among household contacts of unvaccinated cases(22). However, the impact of vaccination on reducing transmission in the context of the more transmissible delta variant appears to be lower(23). https://www.who.int/news/item/24-11-2021-interim-statement-on-covid-19-vaccination-for-children-and-adolescents https://www.who.int/news/item/24-11-2021-interim-statement-o...
