Examination of the vaccine strategies and technical platforms used for the COVID-19 pandemic in the context of those used for previous emerging and reemerging infectious diseases and pandemics may offer some mutually beneficial lessons.

Ginger Eatman thought she was safe after getting her second COVID-19 vaccination in February. But she kept wearing her mask, using hand sanitizer and wiping down the carts at the grocery store anyway. A few weeks later, she noticed a scratchy throat.

"By Wednesday morning, St. Patrick's Day, I was sick. I had congestion — a lot of congestion — and some coughing," says Eatman, 73, of Dallas, Ga.
