while you are correct in your analysis, capitalists are rarely unified in their thinking. which is why the bourgeois state exists: to mediate conflict between factions of the ruling class in the overall interest of Capital. the vast majority of capitalists threw tons of money into creating a vaccine as quickly as possible to get back to business as usual, as they saw this as the best path back to profits and growth, as technological solutions to the problems capitalism creates is what has kept them in power for centuries now.

but there is one faction of capitalist class funding all the anti-mask anti-vaxx nutjob ivermectin shit coming out, which is how it has spread so widely. and they are doing this because they thought the best way to return to profit/growth/normalcy was to try and downplay the pandemic and go on as usual and just let people die and ignore it. they began this line of reasoning before the vaccines were completed, as some were saying it could be years or decades before a viable vaccine was ready to use. that's why they pushed junk like hydroxychloroquine, ideas that covid is no worse than the flu, etc... and now that faction is getting lots of people killed, but they don't care. it's not enough dead workers to disrupt profits more than the lockdowns did, so they are fine with it. hell both factions of the capitalist class would be fine with it if it wasn't straining hospital capacity. i'm sure even the pro-vaccine majority would be fine with it if we just built more hospitals and ICU wards so the capacity wasn't strained, and then went back to business as usual.

see: The fucking Tea Party is behind the "America's Frontline Doctors" group founded by Simone Gold that pushed Hydroxychloroquine with Trump and now Ivermectin
