The GlaxoSmithKline version is called Bexsero, but Pfizer has the patent on Trumenba, which is functionally the same thing. Both are used against bacterial meningitis serogroup B. Note that this is different from the standard meningitis vaccine required in most public schools and universities. Isomeone says they've been vaccinated against meningitis, they almost certainly are referring to the vaccine for serogroups A, C, Y, and W-135, which is different and not effective against gonorrhea.
There are tons of studies demonstrating the effectiveness of both against gonorrhea - it's almost a running joke that every 3-6 months a new one gets published, prompting a slew of articles expressing surprise and amazement, as if this hasn't happened so many times over the last decade that we've lost track. Pretty much all of them point to the range of 40% real-world effectiveness, which is actually quite good from a public health standpoint.
Knowing about it isn't really the main hurdle, though. Even if you know it exists, it's incredibly difficult logistically to get it, because your insurance company won't pay for it unless you've been provably in the vicinity of a MenB outbreak (which is rare in the US), and pharmacies will order it but generally not administer it, so even if you are fine paying for it yourself and manage to get your doctor to prescribe it to you, you'll end up in a weird logistical catch-22 where you can obtain it from a pharmacy but have to self-administer it (do not do this, unless you are trained) or find a not-so-kosher way to get it administered.
