2019. No misinformation here. A lot of scientific researches before COVID, as recent as 2019, don't fit the current Covid narrative. Does science change or politics get involved? Just like they redefined vaccine for the current leaky, not as effective (vs traditional def of vaccine like Polio) 1st generation Covid vaccine.
