This is a pretty limited definition of "vanquished": >The available Lyme vaccine came with several immediately apparent limitations. First, the vaccine efficacy of <80% meant that 20% of fully vaccinated individuals could still get Lyme disease [20]. Second, achieving full protection required three vaccine doses given at the time of the initial dose and 1 month and 12 months after the initial dose. Third, the vaccine safety and efficacy database lacked tests in young children, a population at high risk of developing Lyme disease [3]. Also the vaccine was effective only against the predominant North American Borrelia strain without necessarily conferring protection against international subspecies [16, 22]. Finally, uncertainty about the length of vaccine-induced immunity implied that recipients might need booster vaccine doses as often as every year to prevent waning immunity.
