Not sure how government is helping in finding vaccines but yeah doctors and scientists are working hard and even found many vaccines but they are under trial while some have been proven ineffective.

The funny part of these conspiracy theories is that they are based on assumption of one fact on top of another and they form a pyramid of assumptions because if the bottom of pyramid assumption is not true then all others will fail and chances are high that almost all the theories/assumptions will fail.

The funniest part I read was "Big countries will start occupying small countries, USA + China + Russia will form an alliance" because China and USA are like snake and mongoose who cannot ever agree on something common.
