input: The following are multiple choice questions (with answers) about medical knowledge.   To determine whether the host immune response to gonorrhoea provides limited serovar specific protection from reinfection. 508 episodes of gonorrhoea diagnosed at a city centre genitourinary medicine clinic including 22 patients with multiple infections over a 4 year period. Patients with recurrent gonococcal infection were analysed with respect to the initial and subsequent serovars isolated. No significant difference was seen in the prevalence of serovars isolated following a repeat infection compared with those without repeat infections. The site of the initial infection did not appear to influence the subsequent serovar isolated.   **Question:** Serovar specific immunity to Neisseria gonorrhoeae: does it exist?   (A) Yes   (B) No   (C) Maybe
