A tale of two Covid Americas: can the US unite behind a pandemic strategy?

As health authorities brace for another coronavirus wave, the US is still deeply divided over its pandemic future - even as most states relax restrictions

In Mississippi and Massachusetts, two pharmacists working in very different parts of America have seen a sharp drop in demand for Covid-19 vaccines in recent months. Their best guesses for why they've seen such slowdowns diverge considerably.

Saad Dinno, co-owner and pharmacist at four drugstores in the suburbs of Boston, wagers that most people in his community are up to date on their vaccinations. As he speaks from Acton Pharmacy, in the Massachusetts town of the same name, his bet is a fairly safe one - 95% of the people in this county have had at least one shot, according to the Centers for Disease Control and Prevention (CDC).
