What is attenuated flu vaccine?
Attenuated simply means "weakened". An attenuated flu vaccine refers to vaccines made with live viruses (so you get a good immune response), but they have been weakened chemically so that they are unable to give you the flu. There are two types of flu vaccines available in the US. What is called inactivated, inactive or "dead" vaccine and what is called "live", weakened/attenuated vaccine. The injectable vaccines (intradermal and intramuscular) are made with "dead" viruses and the nasal spray is made with "live" attenuated viruses.
How are viruses attenuated?
Attenuated simply means "weakened". Vaccines made with attenuated pathogens, such as the flu virus in flu nasal mist vaccines in the US, work like any vaccine to trigger an immune response so that your body builds up antibodies to be immune to the virus (or whatever pathogen is intended to be prevented). Flu vaccines made for injection, for example, are made with inactive viruses that are either "dead" or are pieces of the virus that are incomplete so they can not cause disease but can trigger the proper immune response and antibody development. Other vaccines, like the flu nasal mist, use whole, "live" viruses in the vaccine preparation to get a better response and, in those vaccinations, the live viruses are weakened so that they can not make you ill but can cause the proper immunity to be developed.See the related questions below for more detailed information.
What are substances made from dead viruses?
Vaccines for the prevention of the specific viral infection can be made with inactive "dead" viruses. They are also made with live, but attenuated (weakened), viruses. See more below about vaccines.
What is a chemically inactive substance used for comparison with active drugs in an experiment?
Prescription medication
Immunizations have small doses of what in them?
Parts of individual bacteria or viruses that have been killed and broken up into inactive bits. The immune system can recognize them and develop immunity.
Does an injection of antibodies produce active immunity?
No. When you are immunized you are injected with an inactive version of the virus so your body learns how to fight it off and you become permanently immune.
What is the difference between live vaccine and dead vaccine?
Vaccines are usually small amount of the disease you are trying to prevent. Introducing small amounts of the virus or bacteria, whether it is live or inactive, stimulate your immune system to strengthen its defenses against that germ.
