Oral immunization is not invasive, and it is suitable for economical mass vaccination campaigns. Outer surface protein A (OspA) remains the most effective vaccine candidate against B. burgdorferi, with an efficacy of 80 to 100% in mice ( 20 – 23, 25) and 75 to 80% in humans ( 52 ).

Double-blind, randomized, placebo-controlled clinical trials—the most rigorous type of clinical trial used today—were completed for each of two Borrelia burgdorferi vaccines manufactured by GlaxoSmithKline (GSK, formerly SmithKline Beecham [SKB]) and Pasteur Merieux Connaught. The purpose of the study is to obtain safety and immunogenicity data of different dose levels of a multivalent recombinant OspA Lyme Borreliosis (mv rOspA LB) Vaccine with and without adjuvant in seronegative healthy adults aged 18 to 70 years. The outcome shall provide the basis for dose/formulation selection for Section 2 of the study. A total of 143 horses were included in a study to test a commercial vaccine against Lyme borreliosis. The vaccine contained three different antigens (outer surface protein A, OspA) to prevent the infection with spirochetes - B.burgdorferi sensu stricto, B. afzelii and B. garinii.
