Scientists are working quickly to develop a safe and effective vaccine to provide immunity to COVID-19. Once a vaccine is approved, it will likely be imperative for states to authorize as many health care professionals to administer it, since the demand is expected to be extremely high. In addition, legislation authorizing alternative providers within the immunization neighborhood (e.g., pharmacies, schools, workplace, and other clinical sites) can expand the places where vaccines are available and increase access to vaccination among vulnerable populations. By recognizing that not every person is reliably linked to a healthcare provider, these policies can allow for timely and consistent immunization services.
