Question for Experts: What is the obstacle to cloning antibodies at sufficient scale to give everyone a shot of extra COVID-19 immunity? Is it an equipment shortage, red tape, funding issue, or what? Antibodies exist and cloning is current technology. What's the holdup?

I’m fairly certain they can meet demand. They do for their other antibody based products. https://www.rhophylac.com

This is essentially the problem. Antibodies are still, for the most part, derived by harvesting them from an infected human or animal. That all takes time. Producing the appropriate antibodies for COVID will take time, testing, and overcoming regulatory hurdles.

The production chain already exists. Human trials on an anti-sera, developed by CSL Behring and Tekeda, are starting this summer.

Monoclonal ABs will provide passive protection- at least in the prevention of infection with known exposure- like with measles and rabies IgG, & also immunodeficiency patients; may help a person recover faster, and should not inhibit one’s own immune response to make AB’s

But I don’t know the answer to the original question- how fast it takes

Ask the question. How long do antibodies last in a human. 4 weeks? 8 weeks? And is it also dependent of underlying conditions and other medications a person may be on. And just physical dissimilarities? Some people catch the flu after they get a shot.
