The prevention of Lyme disease with vaccine

Lyme disease is a potentially serious and debilitating infection caused by Borrelia burgdorferi that is endemic in North America, Europe, and Asia. Personal protective and environmental measures have not significantly impacted its increasing incidence. An adjuvanted recombinant vaccine (LYMErix™) has been approved in the United States for the prevention of Lyme disease in adults, and has demonstrated both safety and efficacy. A clinical trial of over 10 000 adults showed 76% efficacy following the third dose of a 0, 1, 12 schedule. Accelerated schedules demonstrate equivalent levels of protective antibody. Up to 100% of children 2-14 years of age achieve seroprotective levels of antibody. Booster doses induced protective levels of antibody in more than 96% of recipients when administered at months 12 and 24. Only mild or moderate, transient vaccine-associated adverse events have been reported after immunization. The vaccine is a safe and effective method of preventing Lyme disease.
