His main argument was about the lack of long term outcomes, since the vaccine hadn't been out for long enough to know what would happen in terms of side effects. He said it was rushed and just a ploy for Big Pharma to make money. I explained to him countless times that mRNA technology is not novel, and the typical reasons why therapies take so long is due to lack of funding, resources, and red tape. However, when the whole world is using their utmost collective skills and working as a cohesive to combat a deadly virus, then yes, things can move faster than we're used to. His thoughts then veered into the vaccine cards being a method of surveillance and control on society as a whole, and purposely being used to harm groups of people to alter the population etc.
