herd immunity

The faster spread of the delta variant of the coronavirus makes it harder for public health officials to trace. About 5 to 8 people are likely to become infected from one person with COVID-19 compared with 1 to 3 people at the beginning of the pandemic.

Around the nation, demand for the vaccine overall is decreasing. But many Native American tribal communities are ahead of the rest of the country when it comes to getting COVID vaccines. And, one place in Iowa is getting close to herd immunity.

COVID-19 vaccination rates have slowed in Northeast Ohio and across the country, and combined with new mutations of the virus circulating, health officials fear herd immunity may be out of reach.
