Comvax is a combination vaccine used in children to prevent Hib disease from the Haemophilus influenzae type b bacteria and hepatitis B (a liver infection) caused by the hepatitis B virus.

Yes. While there aren't any combination vaccines available that protect against these two infections together, there are several vaccines that are commonly used today to protect against Hib or hepatitis B alone. Examples of the Hib vaccine include ActHIB and Hiberix, while examples of the hepatitis B vaccine include Recombivax HB and Engerix-B. The separate Hib and hepatitis B vaccines can be given during the same visit to your child's provider's office.
