That was just my impression but it was contradicted by this study.\n\nWhere in post #2565 did I say that I believe press releases from drug companies are the final word? Am I not allowed to be optimistic that antibodies will be at least somewhat effective? I'm glad that testing has started so we can find out. You can be unhappy that tests are being conducted if you prefer.Immunology is quite far from a clearly understood science. It is clear from the polio story from years ago, that both neutralizing antibodies and T cell based immunity can work. They seem to work better if both appear as a result of immunization. That's all I was trying to say.\n\nI'm not at all unhappy that the vaccine tests are being conducted for SARS-Cov-2. However, I am unhappy with the popular press's unquestioning to acceptance of Regeneron's & Eli Lily's spin on things. They develop and sell monoclonal antibodies, not vaccines, and they clearly have their own financial interest in mind.\n\nIf a cocktail of monoclonal antibodies is all it takes to treat Covid-19, that would go against some 30 years of immunological scientific development. I'm not saying it's impossible. But I am saying such an extraordinary finding requires extraordinary evidence to support it.
