It's this thing you inhale ( a live virus ) and its a vaccine for H1N1 or other flues
Attenuated whole-agent vaccine
Varicella Zoster is a type of herpes virus that is commonly the cause of chickenpox. The chickenpox vaccine, often called the Varicella vaccine, is a live virus vaccine to protect against chickenpox, as it can be extremely dangerous in adults. As shingles can also result from the same virus, the vaccine protects against that as well.
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.

The vaccine is given through mouth because it is a live attenuated virus vaccine.
No, the HPV vaccine does not contain live virus. It cannot cause HPV infection or any related illnesses. Here's why: The vaccine uses virus-like particles (VLPs). These are essentially protein shells that mimic the outer surface of the HPV virus, but lack the genetic material needed for the virus to replicate. When your body encounters these VLPs, it recognizes them as foreign and triggers an immune response. This immune response creates antibodies that can fight off actual HPV infection if you encounter the virus in the future. Therefore, the HPV vaccine is a safe and effective way to prevent HPV infection without introducing any live virus into your body.
He proved that a "killed" virus could be successfully used as a vaccine. Other scientists at the time still believed that only a "live" virus injection would give a person immunity. However, using the "live" virus was, according to Salk, more dangerous, and this fact was proven when Dr. Sabin developed the "live" vaccine, the testing of which caused many deaths. Today, vaccines are produced using his "killed" virus methods.
The intramuscular vaccine for poliomyelitis is inactived meaning it is not live the oral vaccine, now no longer used, was live. Go to the CDC.gov website to learn more about vaccines
They changed to inactivated to lower the risk of shedding polio virus after the live vaccine.
Albert Sabin invented the oral live attenuated virus vaccine.
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.
