The most common role of a virus in making vaccines is injection of a live weaken form of the virus. This virus will reproduce poorly once inside the body.
The HIV virus has proven difficult to fight for a number of reasons. One of them is the fact that the virus mutates quickly. That means that the virus changes at the genetic level, making finding a vaccine that works for all variants of the virus difficult if not impossible, thus far.
There is no known vaccination for the virus yet. Only experimental procedures have been used.
An Antonym for vaccine would be Virus

Because a virus can mutate making it stronger and resistant to medication, making the existing vaccine less effective.
Well a vaccine can be a helpful virus.
Salk & SabinThe Salk vaccine was the first and is a traditional killed virus vaccine administered by injection.The Sabin vaccine is an attenuated live virus vaccine usually administered as a drop of liquid placed on a sugar cube and taken by mouth.
vaccine
It means to be given a vaccine to counteract a possible virus.
in this type of vaccine,the vector completed with inserted gene itself act as vaccine virus used as vector are adenovirus,harpes virus
Part of the problem in developing an effective vaccine so far has been the issue of mutation. The HIV virus mutates, or changes, rapidly. What this means for vaccine research and development is that as we are studying the virus and figuring out what will be effective against it, it changes, making whatever we have so far come up with ineffective.
The HPV vaccine is a genetically modified vaccine and therefore is not considered to be live.
