Can viruses be cured by vaccines?
Viral infection can be prevented, but not cured, by vaccines.
Antibiotics only works against bacteria! Since Viruses are not living things, ( because they are single celled organisms) they can only be prevented and can never be "cured". To prevent from obtaining viruses, you get Vaccines (shots). Vaccines are weak or dead viruses injected into your body to release mass amounts of B cells that will help fight against the disease.
What are vaccines for influenza made from parts or products of a virus dead whole viruses antibodies to the virus weakened viruses?
Vaccines are small amounts of live viruses injected into the body. These viruses teach the body's immune system how to fight off the disease. Correction: Some viruses are live. Some are weakened, most flu vaccines are dead viruses, not live, although the nasal mist is a live, weakened virus. Please make sure your answers are correct.
Types of vaccines include attenuated chole agent vaccine, inactivated whole-agent vaccine, toxiod vaccine, acellular vanccine, conjugated vaccine, and subunit vaccine. Live attenuated vaccines contain bacteria or viruses that have been altered so they can't cause disease. Killed vaccines contain killed bacteria or inactivated viruses. Toxoid vaccines contain toxins (or poisons) produced by the germ that have been made harmless. Component vaccines contain parts of the whole bacteria or viruses.
Some vaccines do protect against viral diseases such as the vaccine against chickenpox. However, vaccines against viruses are very difficult to make. Not only are viruses very small, but they are not living organisms. Viruses require a living host to carry on certain processes. Vaccines tend to kill a bacterium or a specific organelle of a bacterium that would affect its ability to survive and carry on its normal functions. Due to the fact that…
Yes, some vaccines have "live" viruses in them, but they have been weakened to the point that they can not make you sick; but still can trigger your immune system to provide immunity to the full strength bug if you encounter it in the wild. These vaccines are called attenuated, which means weakened. Other vaccines are made from viruses that have been destroyed ("Killed" viruses are not technically a "living" thing). They may use them…
They can be either. Some vaccines are made with dead viruses or particles of viruses and other vaccines are made with attenuated (weakened) viruses that are not able to make an otherwise healthy person sick. In 2009 the swine flu vaccine approved for use in the US was prepared both ways, the nasal flu vaccine was made from attenuated viruses and the shots were made with dead viruses.
They are called live attenuated vaccines. Attenuated means weakened. The nasal mist flu vaccine is an example of a live attenuated vaccine. The vaccines for flu that are injected are made from pieces of viruses or "dead" viruses. See the related question below for more information on these two types of vaccines.
What are the incomplete viruses called that have been linked to certain diseases such as scrapie and mad cow?
Mad Cow Disease and Scrapie are NOT caused by incomplete viruses or any virus of any sort. They are caused by PRIONS, which are misfolded proteins much tinier than any virus, complete or not. If such disease were caused by viruses they would easily be cured by an antibiotic, but since they are not caused by bacteria or a virus, such vaccines cannot be made because there is nothing for such a vaccine to target.
No, because it is virus and viruses can`t be cured by antibiotics. Antibiotics are useful for curing bacterial infection. ---------------------------------- Antibiotics, by definition, can only kill bacteria. They are completely ineffective against viruses. However, they may prevent secondary bacterial infections that can occur as a result of severe infections, or certain susceptibilities of the patient. There are no current antiviral medications for treatment of the rhinovirus (common cold) other than cough medicines and other supportive/comfort…
What was the mystery about the polio virus that had to be solved before a vaccine could be developed?
This question seems to be from a unit about Henrietta Lacks' cells. There are many polio viruses that have no effect on humans. Her cells (HeLa) allowed the growth of polio viruses and made it possible to determine which strain produced the devastating effects. When that was determined, the vaccine could be made. Vaccines are not limited to viruses. Some of the bacterial diseases for which there are vaccines include: tuberculosis, meningitis, tetanus, whooping cough…
