It’s shaping up to be one of the worst tick years yet, and concerns about Lyme disease—which is transmitted through the bites of some species—are high. Aside from a short-lived vaccine released in the late 1990s, people have not had the opportunity to get vaccinated against Lyme disease. But if our dogs can get vaccinated, why can’t we? Host Flora Lichtman speaks with immunologist and Lyme disease expert Linden Hu about the ongoing quest for a vaccine against Lyme disease, and our evolving understanding of the disease.
