Passive immunisation is the term used when antibody formed in one individual is given to another individual who is at risk of infection — the protection is temporary. Active immunization is when we give you a vaccine and your immune system kicks into high gear, and sets up a series of reactions in your body to trick your body into thinking that you've actually had the disease. Passive immunization is when you get those pre-formed antibodies. Passive immunity can occur naturally, such as when an infant receives a mother's antibodies through the placenta or breast milk, or artificially, such as when a person receives antibodies in the form of an injection (gamma globulin injection). Passive immunity is provided when a person is given antibodies to a disease rather than producing them through his or her own immune system. A newborn baby acquires passive immunity from its mother through the placenta. Passive immunity is the transfer of antibody produced by one human or other animal to another. Passive immunity provides protection against some infections, but this protection is temporary. The antibodies will degrade during a period of weeks to months, and the recipient will no longer be protected.
Antibodies are proteins made by the immune system to fight antigens, such as bacteria, viruses, and toxins. The body makes different immunoglobulins to combat different antigens. ... Immunoglobulin G (IgG), the most abundant type of antibody, is found in all body fluids and protects against bacterial and viral infections. Immunoglobulin M (IgM) is one of several isotypes of antibody (also known as immunoglobulin) that are produced by vertebrates. IgM is the largest antibody, and it is the first antibody to appear in the response to initial exposure to an antigen. Experiments are being carried out to investigate and establish the efficacy of igG and igM as potential candidates to combat the Virus.

Really , I don't have an idea. And I think It is something related to the specialists and their efforts to develop the effective drug or vaccine and to coronavirus itself and it's new generation.
Yes, this treatment appears to be helpful in the short term until definitive and effective treatments are found.

Antibody forms against a certain genome sequence can protect infection of a person with the virus containing the same genomic sequence against which that antibody was formed but can't protect against virus-containing different genome sequences. As SARS-CoV2 virus rapidly changes its RNA sequence. So, one's antibody might not come into help to others.
I expect it will be very beneficial to eliminate Corona virus because it strengthens patients' immune system.
