A debate is emerging around what it means to be fully vaccinated against COVID-19, as some state and local officials push to change the definition to include an additional dose of a coronavirus vaccine.

Governors in two states in the past week indicated they think three shots are necessary for full vaccination, but public health experts warn such a move would result in massive confusion, and a return to the piecemeal, scattered response that marked the early days of the pandemic.

“We’ve just moved from lots of confusion where most people were not aware, could not figure out, if they were eligible for a booster,” said Jennifer Kates, a senior vice president at the Kaiser Family Foundation.

“If states move out ahead and kind of change their definition of who they’re qualifying as fully vaccinated … that could create a lot more confusion again, because you’d have these different standards all over the country,” she said.
