None. Light and sound waves can be attenuated, but not matter.
Absorbed or attenuated.
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.
Any light beam will go on forever, though it will become attenuated, if not absorbed by intervening matter.
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.
All types of matter have physical properties.
attenuated virus consist of same virus but its capacity to cause disease has deleted by the process of attenuation.

They are called attenuated vaccines. Attenuated means weakened, they do this usually with chemicals and then the attenuated viruses are not able to make you sick, but they are strong enough to trigger the immune response to provide immunity.An attenuated virus. Attenuated simply means weakened. For example, you will see references to this in regard to the flu vaccines. This is also abbreviated when talking about the flu vaccines as LAIV, Live Attenuated Influenza Vaccine.That is a good description of what a vaccine is, although some other substances also could be described similarly. The weakened or killed virus in a vaccine is non-threatening to most people. It can be a problem for infants under six months old, some children and adults with under-developed immune systems or who have immune system disorders.
Attenuated vaccines are created by destabilizing the virulence of the strain while still keeping the organism alive. Attenuated vaccines were first developed by Albert Calmette and Camille Guerin in their efforts to use an immunization as a cure for Tuberculosis in 1906.
No, it's several types of matter.
ALL substances are matter.
Most live attenuated vaccines (influenza vaccines in humans, infectious bronchitis and Newcastle disease vaccines in chickens are types that activate innate immunity responses.
