Unkown: Lymerix, a vaccine to prevent lyme disease, was a 3-dose vaccine given over a 12 month period. At this point in time, no one knows how long the immunity will last. The vaccine is no longer avaialbe so a booster shot is not possible. When walking or hiking in brush and wooded areas wear a reliable insect repellent : 30% deet or 20% picardin. See your doctor if you develop a rash around a tick bite.
