What adverse events are expected after receiving MenB?

In clinical trials and in postlicensure safety surveillance, the most common local adverse events within 7 days of receiving MenB were injection site pain, swelling or redness and the most common systemic symptoms were headache, fatigue and body aches. In general, these types of self-limited reactions are reported more frequently than with MenACWY vaccination.
