The benefactor of vaccines are drug corporations/the medical industrial complex. Their own clinical trials showed the Covid vaccine harms were higher than the benefits. Those trials were prematurely ended to make sure there wasn't more evidence. They've spent their efforts denying vaccine harms and dishonestly overselling the benefits.

The primary benefactor in human induced climate change is fossil fuel corporations and the rich who get to emit large amounts of pollution for free while everyone suffers the price of increased natural disasters, and damaged health. Fossil fuel corporations own research concluded their pollution was harmful but they spent their time denying it.

Both drug corporations and fossil fuel corporations get rich by operating in a non-free market. The drug corporations get patents (monopolies) while the fossil fuel corporations get to make everyone else to suffer the damage their pollution inflicts.

The vaccine enthusiast side in the Covid vaccine debate is closer in substance/style to the fossil fuel side in the climate change debate.

When did anyone of note say that burning fossil fuels would/was causing global cooling?
