Why Holding Second Doses of COVID-19 Vaccines in Reserve is the Wrong Strategy
As of Monday about 9 million Americans, according to the Centers for Disease Control and Prevention, have received the first dose of a COVID-19 vaccine, which is far below the goal of vaccinating 20 million people by the end of 2020. The slow vaccine rollout is occurring at the same time the United States is enduring record levels of infections and deaths. To accelerate vaccinations, some have proposed to delay the timing of the second dose. Critics of this approach argue that it lacks clinical evidence and may weaken the public’s confidence in vaccine effectiveness.
