A lethal infection in mink, the Aleutian disease virus lies dormant in ferrets until stress or injury allows it to surface. While the parvovirus itself causes little or no harm to the ferret host, the large number of antibodies produced in response to the presence of the virus results in a systemic vasculitis, resulting in eventual renal failure, bone marrow suppression and death.

A vaccine is only effective for as long as the body maintains a population of these cells. [8] Attenuated vaccines are “weakened” versions of pathogens (virus or bacteria). They are modified so that it cannot cause harm or disease in the body but are still able to activate the immune system. [20]

It is being used as a vaccine (called MVA-BN, brand names: Imvanex in the EU, [3] Imvamune in Canada, [2] and Jynneos in the US [1]) against smallpox and mpox, [4] having fewer side effects than smallpox vaccines derived from other poxviruses.

Viral immunotherapy is the use of virus to stimulate the body's immune system.

That antigen could be from any species of ...
According to a 2015 study of more than 350 vaccine recipients, side effects are more common among people who get Jynneos intradermally than those who receive the bigger, deeper subcutaneous shots ...
