In an experimental situation, a rabbit is exposed to a viral antigen to which it makes antibodies. these antibodies are then purified and injected into a human with the same viral disease. this is an example of

Passive immunization

Explanation:

Passive immunity is a situation where there is a transfer of ready-made antibodies to the recepient. In this situation, the transferred antibodies help to prevent virus and infetious diseases. The downside of this type of immunization is that, the protection it offers doesn't last long, it may last for a few weeks or a few months. We have both natural and artificial passive immunization.

In this case, since the rabbit is exposed to a viral antigen to which it makes antibodies, and the antibodies are then purified and injected into a human with the same viral disease we can say a passive immunization has taken place and it is of artificial type.

surface modification is a versatile tool and has been widely used in material science and engineering that has significantly facilitated the study and characterization of complex materials. at  matexcel, experienced experts in surface science can offer tailored efforts to meet the specific needs from our clients.
