They're true.
Big pharma constantly spreads theories about how vaccines don't work enough and you need to get boosters every three or four months (lie), they spread propaganda about how their competitor's vaccines are not safe (lie), and Cuba is vaxxmaxxed despite being big pharma free.
Also, rules and regulations around "testing" and other bullshit are completely detached from reality of how vaccines are produced, and the technological advancement since early 20th century. They're designed so that nobody except big pharma can produce vaccines, because nobody can afford to get testing done as required by regulations.
Also, vaccines are so dirt cheap that making them is a net loss for big pharma. They prefer to sell you shitty medicine. Fact: the "cheap and affordable" snake oil corona treatments that don't work were ALL more expensive than vaccination.
