They didnt research anything. It was developed in what? 2 or 4 weeks? The long term effects are unknown. Marxist funded "research". Same people who fund reasearch grants given to "scientists" for global cooling, global warming and climate change. Scare the sheeple into compliance.
Something they wouldn't tell us is that the pharmaceutical companies have done many studies on mRNA for many years. They buried those because they did not provide the outcomes they desired to take their potions to market and make the big bucks....
Lab animal trials were complete failures. The mRNA experiments resulted in high mortalities all the time. The leadership like Fauci and Gates and pharma CEOS knew this. They are all mass murderers.
