MenB vaccine offers men no protection from gonorrhoea, claims major study

• MenB vaccine provides no protective benefit against gonorrhoea infection in men, contradicting previous assumptions about cross-protective immunity
• Current recommendations to offer MenB to at-risk men may need clinical reassessment based on this evidence of ineffectiveness against gonorrhoea
• Alternative prevention strategies for gonorrhoea in high-risk populations should be prioritised, as MenB cannot be relied upon for this indication

The Meningitis B vaccine does not prevent gonorrhoea infections despite being offered to at-risk men, scientists say.
