Optimmunize is a research network to examine non-specific and sex-differential effects of vaccines.

Optimmunize aims to raise international scientific awareness, and drive forward the much needed studies required for the biological mechanisms to be understood and exploited in vaccine implementation programs. If vaccines can be shown conclusively to have non-specific effects on morbidity and mortality, and the sex differences and their mechanisms are confirmed, this will have major public health implications and raise the imperative issue of whether males and females require different vaccine schedules. 


In 2020, at the Welcome Trust campus in Cambridge, Optimmunize hosted the worlds first conference on non-specific effects of vaccines


Optimmunize has held many meetings, with participation from researchers from all over the world.
