Hmmm I'm totally just babbling here but this makes me think if it'd be possible to just engineer a harmless strain that is more effective at being transmitted (or perhaps even circumvents vaccines better). Then instead of worrying about vaccinating people we could just try to have that strain spread faster than the harmful ones
A similar thing happened in some South American countries with a cholera outbreak. Strains that made people more sick forced them to stay inside whereas the more harmless strains allowed people to socialize more and the harmless ones ended up spreading faster
