The Centers for Disease Control and Prevention predicts that a new, more contagious version of COVID-19 will become the predominant strain by March, testing the new vaccine’s effectiveness. At the same time, researchers are trying to find ways to get the vaccine to more people more quickly by lengthening time between doses, with unknown results. Infectious disease experts discuss where we are in the fight.
A COVID-19 vaccine is on the horizon, but while billions have been spent on its development, little has been spent on distribution and there are still many unanswered questions. Experts discuss how vaccine distribution might be carried out, how long it’s likely to take, and the steps needed to make it work.
