Donald Trump may be “very confident” we will have a vaccine for COVID-19 by the end of the year, but the rest of us should be more cautious. Billions of dollars are being spent trying to develop vaccines and treatments as a more permanent solution to the crisis than the lockdowns currently being enforced around the world.

As of May 2020 there are 182 treatments and 99 different vaccines being developed globally. But, based on recent history, only one or two are likely to be transformative, a couple may be partially helpful, some will be shown as downright dangerous, and the majority will have conflicting evidence as to their effectiveness.
