Don't count on any legit vaccines anytime soon or ever, unless for them a legit vaccine has the efficiency of the annual flu shot (1.5% to 8% effective). I trust the nobel prize winning immunologists who mention the fasted vaccine ever created took 4 years and they've been working on a coronavirus vaccine since SARS and made it exactly nowhere.
Best hope is this high CBD Sativa mouthwash from Alberta that Health Canada invested in becomes readily available. Then we're talking.
