Patent law does not allow for someone to patent or own a living organism. However, we have seen companies such as Monsanto modify the genetics of plants to make them grow with less water and that allows them to patent and own the genetically modified thing.
If you apply the same concept to those who are taking mRNA vaccines, they could be considered property of the pharma companies.
In this twisted clown world, I would not put it past someone to try this and claim everyone who took said vaccine is now owned by these sick people. Vaccine yourself and you just signed up to be a slave. No thanks.
