Comvax Uses

How Does Comvax Work?

This vaccine contains hepatitis B surface antigens, which are proteins on the outer surface of the virus that can be recognized by the immune system. Unlike older versions of the hepatitis vaccine, currently available vaccines, including Comvax, are not made using human blood products. Instead, they are made using recombinant DNA technology. This vaccine is not "live," which means that there is absolutely no chance a person could get hepatitis B from it.
Comvax also contains Hib polysaccharides, which are sugar molecules from the outside coating of the Hib bacteria.
The components of this vaccine "trick" the body into thinking it has been exposed to Hib bacteria and hepatitis B virus, without the risk of being exposed to the actual bacteria or virus. The body produces antibodies that will help fight infection if future exposure occurs.

Using Comvax in Older Children and Adults

This vaccine is not approved for individuals over 15 months of age.

Off-Label Uses

On occasion, your healthcare provider may recommend Comvax for something other than the purposes discussed in this article; this would be known as an "off-label" use. At this time, giving Comvax as a catch-up vaccine for individuals over the age of 15 months is considered an off-label use.
