I've always believed when it comes to democrats, you follow the money. When it comes to the left, they only care about public safety when there's green to be made (weak border, bail reform, mass releases, "summer of love", etc).
My belief is that the giant vaccine push (especially keeping in mind how lax left leadership is with being precautious, wearing masks, not gathering -- "racism more deadly than Covid") is a government money-laundering scheme. The high government buy vaccine stocks (think Pelosi insider-trading), then mass push vaccines, especially with mandates (getting fired as punishment for not making them cash) on the tax-payer dollars, causing the huge stock growths of vaccine companies, thus boosting their dividends.
There's even reports out there of people becoming mega-rich because of their part or proximity to vaccine creation.
