Long-term effects of immunization with recombinant lipoprotein outer surface protein a on serologic test for lyme disease.

Immunization with recombinant lipoprotein outer surface protein A vaccine is known to interfere with some serologic tests for Lyme disease. We tested sera from 152 vaccine recipients by using in-house and commercial Western blot assays and found that vaccination caused interference in up to 25% of recipients and can persist for over 6 years.
