We create a drug which specifies to kill a certain part of the virus, however the virus changes its forms. So, the drug ends up killing the virus's competitors, which allows it to thrive more. This makes the drug useless.

∙ 13y ago1.The virus mutate and change shapes quickly and also aim at destroying the white blood cells at a faster rate than other diseases,
The big problem in all treatments is HIV's rapid rate of mutation.
2. Every virus that comes out of a cell is slightly different from the one that went in.
3.It doesn't take long for drug resistant viruses to appear in the blood.
4. Like the common cold, the HIV virus changes so fast that it's difficult to develop an effective vaccine.

Is the flu vaccine effective against all types of flu?
No. These viruses mutate rapidly and you can not get one vaccine for all of the subtypes.
The some hive cells mutate making it difficult to produce a vaccine?
proteins!
Why vaccine is not developed for viral fever?
because viruses responsible for viral fever are many and mutate very rapidly.
Do flu viruses have a high mutation rate?
Yes, viruses do mutate very easily. This is one reason the cure for the common cold is so elusive, before a vaccine can be created for the strain of rhinovirus or other virus that is causing the currently circulating common cold, the viruses will have often mutated to a new form making a vaccine ineffective.
What are the six traits of viruses?
Viruses have six traits that characterize them. They are: They can produce at a high rate, they can mutate, they are acellular, they have no metabolism, they either have DNA or RNA, and they are dependent on a host cell for replication.
Do viruses evolve?
Yes, viruses evolve over time. They will usually mutate into a stronger virus. When viruses face something new that could stop them, they usually mutate.
Why are viruses hard to cure?
If you are talking about virus as in illnesses, then it is because they are immune to antibiotics and mutate. If you are talking about computer viruses they are hard to totally eliminate as they constantly mutate
Why are virus not curable?
Viruses replicate fast and mutate easily.
Can viruses mutate to infect new species?
Yes, viruses can mutate to infect new species.
How long does it take for a virus to mutate?
The time it takes a virus to mutate varies depending on the virus. However, viruses mutate frequently so it is very difficult to completely eradicate a virus.
Is HIV a stable virus can it mutate?
The HIV virus is highly unstable, meaning that it does mutate quickly. That has been part of the dilemma in finding a cure, or even a vaccine against the virus.
Why is vaccine developed for influenza but not for rhinovirus?
Because the rhinovirus (which is one virus that causes the common cold) mutates and changes its structure extremely frequently as do the other viruses that cause the common cold, such as Coronaviruses, and any of the others of hundreds of viruses that cause colds. While influenza strains also mutate, it is not as quickly as cold viruses that almost constantly are mutating, resulting in several dozen active viruses in any one locality. In addition, influenza has proven reasonably easy to grow in labs for study and for vaccine production, while cultivating rhinoviruses has proven very difficult.
