How much will the covid-19 vaccine cost?

Largely free but the actual cost of getting vaccinated could vary: The federal government has stated that the first round of vaccinations will be free for Americans, and the Affordable Care Act (ACA) requires that health insurers offer recommended vaccinations at no cost to members. This regulation does not apply to short-term insurance plans, so the actual cost of getting vaccinated could vary. President-elect Biden has promised to "guarantee the vaccine gets to every American, cost-free", but this will be subject to congressional authorization of additional spending, and may depend on whether the president's party also controls the senate.
