Louisiana’s surgeon general announced late Thursday that the state health department "will no longer promote mass vaccination." Here's what that could mean.

Louisiana Surgeon General Ralph Abraham has ordered his staff to stop engaging in media campaigns and community health fairs to encourage vaccinations.

New Orleans has it's own health department -- which is not bound by Abraham's directive -- and city officials told the Times-Picayune it would continue to promote seasonal vaccination events, adding that they are often the only way senior, rural and low-income residents can access vaccinations.
