#4CMenB
So how does this work?
Meningococcal disease and gonorrhea are caused by different versions of Neisseria bacteria
An existing mening vaccine, 4CMenB, includes part of the bacteria’s outer layer. The idea is that the two different bacteria have similar outer layers, so 4CMenB gives cross-protection

England to begin vaccination program to prevent gonorrhea

Starting in August, eligible patients can receive shots of 4CMenB, a vaccine for meningococcal B disease that provides moderate cross-protection against gonorrhea.

UK begins gonorrhea vaccination program

The UK's National Health Service is offering the 4CMenB vaccine, which provides cross-protection against gonorrhea, to patients at the greatest risk of infection.

Observational evidence suggests that the four-component meningococcal B vaccine (4CMenB) may reduce gonorrhea risk. In the GoGoVax randomized trial, 4CMenB did not result in a lower incidence of 𝘕. 𝘨𝘰𝘯𝘰𝘳𝘳𝘩𝘰𝘦𝘢𝘦 infection than placebo. Read the full trial results: https://nej.md/4wv9Qwi

It's funny how the antivaxxers in charge of our vaccination policy claim to want to have our vaccine schedule to look like those of Europe, but then don't think about the fact that much of Europe does 4CMenB vaccination at 2-3 months, which often triggers fever and then forces a sepsis workup.

Long-term 4CMenB vaccine effectiveness against gonococcal infection at four years post program implementation: observational case-control study
A four-component meningococcal B (4CMenB) vaccine program was introduced in adolescents in 2019 in South Australia. We aimed to evaluate long-term vaccine effectiveness (VE) and impact (VI) on gonococcal infection four years after implementation of the program.

Meningococcal B vaccine fails to prevent gonorrhea, trial finds

Among gay and bisexual men with a history of gonorrhea infection who received either the 4CMenB vaccine or placebo, gonorrhea incidence was essentially the same—roughly 48% in both arms.

New insights into gonorrhea natural history and protection by 4CMenB, and a call for more analyses of existing studies and enhanced data collection
Dear Editor The 4CMenB meningitis B vaccine has been reported by multiple studies to provide partial protection against gonorrhea, with trial-based evidence currently inconclusive.

Yes some MenB vaccines show partial protection against gonorrhea. The signal is strongest for 4CMenB (Bexsero), an OMV-based MenB vaccine: multiple observational studies and reviews estimate roughly ~30–50% effectiveness against lab-confirmed gonorrhea.

We've seen an increase in cases of mpox over recent months, but levels remain much lower than during the 2022 outbreak.

For those who are eligible, the mpox vaccine is available routinely along with other vaccines such as 4CMenB for gonorrhoea , HepA, HepB and HPV.

February 12, 2026 at 3:36 PM
Biological plausibility is high: OMV vaccines like 4CMenB include antigens shared between Neisseria meningitidis and Neisseria gonorrhoeae but this protective effect was not confirmed in a randomized controlled trial.
October 19, 2025 at 12:35 AM
Meningococcal B vaccine ddi not prevent Gonorrhea in this RCT. It is a negative result but an important one which emphasizes the need for N. gonorrhoeae specific vaccines. We are seeing higher rates on gonococcal infections and more drug resistance globally.
