Controversy over raw milk reflects the push-pull the Trump administration faces in rolling back regulations and offering consumers more choices. For now, the CDC still recommends against consuming raw milk and the FDA bans its interstate sale.
Several vaccines against extracellular bacteria have been developed in the past and are still used successfully today, e.g., vaccines against tetanus, pertussis, and diphtheria. However, while induction of antibody production is usually sufficient for protection against extracellular bacteria, vaccination against intracellular bacteria is much more difficult because effective defense against these pathogens requires T cell-mediated responses, particularly the activation of cytotoxic CD8+ T cells. These responses are usually not efficiently elicited by immunization with non-living whole cell antigens or subunit vaccines, so that other antigen delivery strategies are required.
Don’t even bother. They think you can vaccinate against bacteria. And they’ve doubled down on it three times now.
