Tennessee pharmacies are selling ivermectin, a medication that has been touted for unproven uses, with some pharmacies reportedly led by an individual who opposes vaccination. The state has allowed pharmacies to sell ivermectin without a prescription, despite research indicating it has no benefit for treating a specific condition. The situation in Tennessee is part of a broader discussion about healthcare and vaccination efforts, with some outlets reporting on related issues such as measles outbreaks and vaccination policies.
