Below are some frequently asked questions about Bexsero.
Is the dosage of Bexsero similar to the dosage of Trumenba?
Bexsero and Trumenda are both vaccines used to help prevent meningitis B. They are injections given into a muscle in the upper arm. There are slight differences in the time between doses for each vaccine.
Bexsero is given as two injections. The doses should be given at least 1 month apart.
Trumenba can be given as a two-dose or three-dose series, depending on the risk of meningitis B. Most children and adults will receive two doses given 6 months apart. If you or your child is at a higher risk of meningitis B, a doctor may recommend the three-dose series. In this case, a second dose is given 1–2 months after the first dose. The third dose is given 6 months after the first dose.
Both (or all three) doses you receive should be given with the same vaccine brand. Even though both Bexsero and Trumenda help protect against meningitis B, it isn’t known whether using different vaccine brands in a series is safe or effective.
