Ingham County reports just over 59 percent of its residents aged 16 and up have received at least one dose of a COVID-19 vaccine.
Overall, the county has seen nearly 23,000 positive cases since the start of the pandemic. Health Officer Linda Vail says the highest infection rate right now is among people aged 20 to 29.
“Part of that could be because a lot of our older population is vaccinated, and so that virus has just got to keep moving to whatever population it can find to still infect and replicate in,” she said.
She attributes some recent spread of COVID to the Delta variant of the virus.
Vail says people who are fully vaccinated should still keep their face masks around because of the possibility of so-called “breakthrough cases.”
"You’ve got kind of this armor of protection around you," she said. "It’s going to protect you, but if you start to throw virus at people, like through a firehouse, an inordinate amount of virus circulating in the community, that’s going to create the possibility of more of those breakthrough cases.”
She adds those kinds of cases typically produce mild illness.
