"One thing we do know is that some of the vaccines currently being tested in humans are already causing serious side effects. The side effects are likely a result of the powerful ingredients added to the vaccine to help inflame the body's immune system. These ingredients -- called adjuvants -- help vaccines work better, but if they can land the young and healthy patients in the clinical trial in the hospital because of high fevers and fainting, imagine what they might do to those already ill with secondary conditions or to those who are older. Indeed, the elderly may need repeated doses of the vaccine, given how resistance to some vaccinations becomes progressively more profound with time.
But even without a vaccine, there is reason for hope that a medical solution to the crisis will soon be at hand. It will likely take the form of anti-Covid drugs that will be able to treat patients newly infected and prevent others from becoming ill. These drugs can likely help us bridge the gap between where we are today -- with only masks, hand hygiene and physical distancing to protect us -- to where we hope to be tomorrow -- with a vaccine in hand."
