If Lyme has become so common, why isn’t there a vaccine for it? About 30,000 cases of Lyme disease are reported to the Centers for Disease Control and Prevention each year.. And experts estimate that the actual number of cases is more like 300,000 per year. A vaccine for Lyme disease-- found to be 76 % effective in adults after 3 doses.called LYMErix, was released in 1998. Studies never showed a direct link between LYMErix and any chronic side effect or serious complication. But patients’ claims about it, and resulting media coverage, were sufficient to make doctors and patients wary & sales dropped. A European company called Valneva says that it is making progress on VLA15, a vaccine that would protect against six strains of Lyme, including the one most prevalent in the USTs being tested now, and the company hopes to seek licensing in about five years. Wait!What? 5 years?
