policy would be to provide a subsidy, like a voucher, to any citizen who wishes to get vaccinated. This voucher

would act as “income” that one could use to purchase only a flu shot and, if the voucher were exactly equal to
the per-unit spillover benefits, would increase market equilibrium to a quantity of QSocial and a price of PSocial
where MSB equals MSC (which equals MPC given the assumption that there are no spillover costs in producing
the vaccine). Suppliers of the flu shots would receive payment of PSocial per vaccination, while consumers of flu
shots would redeem the voucher and only pay a price of PSubsidy. When the government uses a subsidy in this
way, it produces the socially optimal quantity of vaccinations.
