Do persons with a previous history of poliomyelitis disease require polio vaccination?
A. Poliomyelitis occurs following infection with one of three serotypes of polio virus (1, 2 and 3) [1]. Infection with one virus type does not confer immunity to the other two types. Therefore, persons with a history of poliomyelitis only have type-specific immunity and will not be fully protected against other polio serotypes. A previous history of poliomyelitis disease is not a contraindication to vaccination with poliomyelitis vaccine [2]. All previously unvaccinated individuals, including those with a history of poliomyelitis, should receive a primary course of three poliomyelitis containing vaccines (appropriate to their age group) with an interval of at least one month between each dose. Booster doses should be given at the appropriate interval according to UK guidelines. References: 1. Chin J. editor. Control of Communicable Disease Manual. 17th ed.
