With the latest (mostly) good news about the effectiveness of a COVID-19 vaccine from AstraZeneca, there’s a chance that Americans will soon have cheap or cost-free access to no fewer than three different immunity-inducing shots for the novel coronavirus.
But there’s a point at which all this abundance could become a problem—or at least get confusing. Each vaccine has its own production, shipping, and storage requirements, as well as dosing guidelines. Sorting out which hospitals, clinics, and pharmacies get which vaccine and when—and then administering not just one but two injections to hundreds of millions of Americans—is a huge undertaking. Suffice it to say you almost certainly will not be in a position to have your pick from a vaccine menu.
