Dr. Bob Bollinger, Medical Director at emocha and Professor of Infectious Diseases at Johns Hopkins University School of Medicine, spoke with CNBC about COVID-19 vaccination in schools this fall. Dr. Bollinger advocates for vaccine incentives, rather than mandates, and most superintendents indicated they agree. “It’s always better to reinforce positive behavior rather than mandate,” Dr. Bollinger told Jessica Dickler. But if the virus continues to spread at high rates, he suggested vaccine requirements may become more widespread. “If you can provide the incentives to get the vaccination rates high enough to reap the benefits, that’s great,” Dr. Bollinger said. “If you can’t, we are going to have to be thinking hard about other strategies to get us there.”
