Our government has pushed hard to get people to have four jabs and is starting to agitate for a 5th.
Proving (a) the Covid vaxes don't work because (b) after 3 months all fake immunity from the previous jab goes away and your natural immune system takes over.
Governments don't want anyone to have natural adaptable response to covid virus as it mutates as that will stop the UN population reduction agenda from being effective through mRNA drug distribution.
