i think that they are produced in cells.
INTERFERON is a substance produced by body cells when they are attacked by viruses.
The cycle of infection
The lytic cycle of infection occurs when more viruses are produced and the host cell is destroyed. This is the phenomenon that occurs in viral illnesses.

Viruses must be produced in a host cell. They can be produced in vitro (in glass) if there are host cells in there first.
substances produced to help body cells resist viruses
All viruses kill they cells that they infect. If not right away then later.

Antibiotics are the chemicals produced by microorganisms to inhibit the growth of other microorganisms. most of the antibiotics are produced by fungi. Very few are produces by bacteria. For example the antibiotics Monobactum, Bacitracin and Polymixin B are produced by bacteria. They almost all act against other bacteria and not viruses. ( Amphotericin B acts against fungi and is too toxic.) In fact you do not have good drugs against viruses and then you conveniently avoid to talk about it.
to avoid development of resistance of strain of bacteria or 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.
