Chumakov also created a number of other human and veterinarian vaccines, including inactivated vaccine against TBE, measles, influenza and vaccine against Canine distemper virus that is widely used to protect farmed fur animals. Chumakov published more than 960 research papers, scholarly articles and books.
Vaccination is the administration of a vaccine to help the immune system develop immunity from a disease. Vaccines contain a microorganism or virus in a weakened, live or killed state, or proteins or toxins from the organism. In stimulating the body's adaptive immunity, they help prevent sickness from an infectious disease.
Vaccines may be monovalent (also called univalent) or multivalent (also called polyvalent). A monovalent vaccine is designed to immunize against a single antigen or single microorganism. [82] A multivalent or polyvalent vaccine is designed to immunize against two or more strains of the same microorganism, or against two or more microorganisms. [83]
Vets are looking into a mystery dog illness in 2023, which may be a virus. It's going around the U.S. and can be fatal. What to know about symptoms, prevention.
It is impossible with other vaccine technologies such as inactivated vaccine (killed-virus vaccines), viral vector vaccine, RNA vaccines (that contain no virus), [14] or subunit vaccines (a vaccine technology using only isolated proteins of a virus). Only a small number of vaccines use technology that contain live virus which can theoretically ...
The purpose is to reduce the risk of death and suffering, [1] that is, the disease burden, even when eradication of the disease is not possible. Vaccination is the chief type of such immunization, greatly reducing the burden of vaccine-preventable diseases. Immunity against infections that can cause serious illness is beneficial.
Canine influenza (dog flu) is influenza occurring in canine animals. Canine influenza is caused by varieties of influenzavirus A, such as equine influenza virus H3N8, which was discovered to cause disease in canines in 2004. [1] Because of the lack of previous exposure to this virus, dogs have no natural immunity to it. Therefore, the disease ...
An inactivated vaccine (or killed vaccine) is a type of vaccine that contains pathogens (such as virus or bacteria) that have been killed or rendered inactive, so they cannot replicate or cause disease. In contrast, live vaccines use pathogens that are still alive (but are almost always attenuated, that is, weakened).
