There are many and several types of meningitis, and over 3000 cases per annum. Just because a vaccine exists does not mean it is good value to governments treating populations. Just as screening tests have to meet certain criteria, so with vaccinations. The Zars virus is a case in point as it is now threatening many people across continents so a vaccine will be a public good. Meningitis B is a relatively uncommon infection, and rational rationing supports government policy. But we don’t officially have rationing at all, so NHSreality supports the demand for Men B public vaccination to all children under 11, and why not anyone who requests it?
Meningitis B and C are reducing in frequency as living standards increase. There is a cost to a vaccination program, and once started it will be difficult to withdraw. Screening for breast and cervical cancer services being an example of where the gain has occurred already, but there would be such an outcry if withdrawn and the resources put into more useful returns.
