What is a vaccine made with live weakened flu viruses that do not cause the flu?

In the US, that would be the vaccine used in the H1N1/09 nasal spray vaccinations. These weakened viruses used to make that nasal vaccine are called attenuated, which means weakened. The weakening is usually done with chemicals. People aged 2 to 49 can use this nasal spray vaccine. Those younger or older should use the flu shots which are made with inactivated ("dead") viruses.

What is injection of weakened viruses is called?
A vaccination using a vaccine made from attenuated live viruses.
What consists of pathogens that have been weakened?
Live vaccines contains weakened viruses of the disease. These viruses can not cause the disease but give immunity to the recipient. ( In the initial days of such trials, 18 patient got the rabies due to vaccine and died.)
What is a vaccine that contains live weakened pathogens?
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 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.
Is the tuberculosis vaccine a live vaccine?
TB vaccine is a live attenuated vaccine (LAV). This type of vaccine prepared from living micro-organisms (viruses, bacteria currently available) that have been weakened under laboratory conditions.LAV vaccines will replicate in a vaccinated individual and produce an immune response but usually cause a mild or no disease.
Can Gardasil cause HPV?
No. This is not possible. The Gardasil vaccine contains recombinant proteins from HPV to provoke an immune response. There are no live viruses, attenuated viruses or even dead viruses in the vaccine. The viral DNA is not present in any form.
What is used to make the measles vaccine-?
The active ingredient is the live, attenuated (weakened) measles virus.
What injection Contains weakened bacteria?
The injection that contains weakened bacteria is called a live attenuated vaccine. This type of vaccine is created by modifying the bacteria so that it is weakened or unable to cause disease, but still capable of stimulating an immune response. Live attenuated vaccines are used to prevent diseases such as measles, mumps, rubella, and chickenpox.
When you get a vaccine can you get the virus?
There are a few circumstances that can create some risk of getting the virus, such as in people whose immune systems aren't working right (e.g., they recently had cancer chemotherapy or HIV or some other immuno-suppressive disorder). See the list of people in the related question below who should not get vaccinated with the types of vaccines that contain a live "attenuated" virus. Attenuated means weakened. When someone has a weak immune system, they may be susceptible to the weakened form of virus in the vaccine. But they would not be able to be sick from getting vaccines that contain "dead" viruses. With the flu vaccines, for example, the shots have dead viruses in them but the nasal mist has live attenuated viruses in it.Sometimes. If the vaccine is a live attenuated (weakened) vaccine, then you get a dose of virions (viral particles/viruses) that are no longer dangerous to humans as they have been weakened so they can not make you sick. Other vaccines (such as Gardasil) are made with Virus-like particles (VLP) and these are just pieces of the virus (such as the envelope) not actually working and replicating viruses so they can not make you sick either.
Is there any danger for someone taking the drug interferon for melonoma being around a baby who just received an immunization shot?
With influenza vaccinations, if the child had the vaccine given by injection (flu shot) and not by nasal spray, then the vaccine would have been made from inactivated viruses and not from weakened, but still live, viruses. The live virus vaccines are the ones that have potential infection problems for the immunocompromised person.
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.
Why are flu vaccinations produced from dead virus and not live viruses?
In the US there is a flu vaccination made with live viruses that have been weakened (attenuated) to prevent them from making otherwise healthy people sick. This type of vaccine can be used by those who are healthy and aged 2 - 49. It creates a very good immune response to cause immunity and so it can be administered in an intranasal mist that is inhaled into the nose instead of having to be given in a shot. The vaccines for flu that are made to be injected in a shot are made from "dead" viruses or pieces of dead viruses. So flu vaccinations are produced from both "dead" viruses and live viruses.
