Ticks Are Expanding: Vaccine News and Practical Tips to Prevent Lyme Disease and Alpha-Gal Syndrome

Ticks are spreading into new areas, raising Lyme disease and alpha-gal syndrome risks. Scientists are advancing vaccines (Pfizer’s Lyme vaccine showed strong results) and other therapies, along with improved diagnostic tests, with the long-term goal of a universal anti-tick vaccine. In the meantime, individual prevention matters: use EPA-approved repellents, treat clothing with permethrin, check yourself and your gear after outdoor time, and beware that tiny summer nymphs are easy to miss. Early diagnosis and staying informed are key, even as concerns about federal funding for tick biology linger.
