Wild fact

No Current Lyme Vaccine

An FDA-approved Lyme vaccine for humans (LYMErix) was on the United States market from 1998 to 2002 before being withdrawn over weak demand and unproven safety concerns. As of 2026, no Lyme vaccine is licensed for humans in the United States; a candidate from Pfizer and Valneva is in late-phase trials. Veterinary Lyme vaccines for dogs remain widely used.
