A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes.
Viral vaccines contain either inactivated viruses or attenuated (alive but not capable of causing disease) viruses.
Inactivated or killed viral vaccines contain viruses, which have lost their ability to replicate and in order for it to bring about a response it contains more antigen than live vaccines. Attenuated or live vaccines contain the live form of the virus. These viruses are not pathogenic but are able to induce an immune response.
