Monoclonal antibodies (MAB) are lab-created proteins that help those already infected deal with the virus. They have been intensively deployed in Alabama, Georgia, Florida, Louisiana, Mississippi, Tennessee and Texas – states dealing with the recent surge of Delta-variant cases. With the exception of Louisiana, they are all run by Republicans.

On Wednesday, the Biden administration announced it would take over the distribution of these treatments using the Defense Production Act and would be centralizing them under the Department of Health and Human Services (HHS). A HHS spokesperson said this was being done to avoid shortages, as the seven states account for 70% of all orders.

"Given this reality, we must work to ensure our supply of these life-saving therapies remains available for all states and territories, not just some," the spokesperson told CNN.

"HHS will determine the amount of product each state and territory receives on a weekly basis. State and territorial health departments will subsequently identify sites that will receive product and how much," the spokesperson said. "This system will help maintain equitable distribution, both geographically and temporally, across the country – providing states and territories with consistent, fairly-distributed supply over the coming weeks."
