Not so crazy. Certain threads have posters whose main activity seems to be to defend the CCP or Russia, and attack the west.
Indeed Russia is believed to be have been recently busted actively spreading disinformation through social media- not the west is short of useful idiots already.

Not promoting or saying the CCP or Russian government are good guys. However the links are to a Russian businessman, not to Russia in general, yes that is a sort of smoking gun, but the same disinformation comes out of similar businessmen in Australia like Palmer and Co. Just because Palmer is a raging lunatic does not mean all of Australia is. A lot of whacko anti-vax ideas come out of the USA and other "western" places including Australia, and yes there are most likely some underhanded international efforts going on as well. Within Australia we have Neo-Nazi groups and such linked with other organised groups that revel in anarchy and will spread this info without any push from a foreign nation, do not underestimate how much reach and finance these groups can muster. Then you have religious and other groups, that can be just as devious as they know the direct message from "god" can seem like lunatics words so they hide behind false scientific information.
End game is, that's your irrational 10% who are non vaxers. You won't be able to change their narrative, just look out for it and be wary of it.
Do masks work?
The best example I've seen this whole pandemic.
