How effective is the meningococcal vaccine?
8 doctors weighed in across 2 answers
70-85%: Depending upon which vaccine strain you are talking about, a single dose will create a seroresponse (or documented immune response) roughly 70-85% of the time. When used broadly, this will translate to an 85-100% efficacy in reducing infection rates in kids. Currently, the CDC now recommends a second dose - after the second there is almost 95-100% response with very high titers.
