Despite the increase in projected doses, health experts are warning that early vaccinations will not drastically control the spread of the virus. Bryan Lewis, a computational epidemiologist at the University of Virginia, says that’s an intentional part of the distribution design. “What we’re really trying to do with these first doses is protect the people who need to be protected the most,” he said. “These first shipments of this vaccine are mainly targeting saving lives and allowing the hospitals to function.”
