Is Bexsero’s dosage similar to the dosages of Trumenba?
Yes. Bexsero and Trumenba are both meningococcal group B vaccines that are given as injections into a muscle. However, they have slightly different dosing schedules.
Bexsero is given as two injections at least 1 month apart.
On the other hand, Trumenba may be given as two or three injections. Most children and young adults ages 10–25 years old will receive two doses 6 months apart. But if your child is at higher risk of meningitis B, their doctor may recommend three doses of Trumenba. In this case, the second dose is 1–2 months after the first dose, and the third dose is 6 months after the first dose.
Although both vaccines protect against meningitis B, they aren’t interchangeable. You should continue with the same vaccine for your second (or third) dose. To learn more about how these vaccines compare, talk with your doctor or pharmacist.
Will Bexsero still work if I receive my second dose of the vaccine late?
