I can tell you that they are extremely difficult to produce, and extraordinarily expensive, as I happen to take one. Without insurance, the cost of mine is 12,000 a month. The reason is that the company who invented it spent hundreds of millions doing so, and they're allowed to recoup their costs.
The patent on mine expired a couple of years ago, but the company has the government tied up in court to prevent that expiration. Even if other companies could get the "formula", it would still be very expensive to produce and thus still expensive to purchase, although not 12,000. My husband will have to keep working until he's 80 at this rate, just to keep the insurance. Medicare, our "senior" public health care system, would make me pay 7,000 a month, which is impossible.
I'm not sure of this, but I've been told that in some European countries the state health systems just don't make it available period because it's too expensive. I'd love to know more about that aspect of it.
Perhaps to salve their conscience, the company "says" that arrangements can be made for those who absolutely can't pay.
The monoclonal antibody for Covid is a different one and highly toxic in terms of side effects. That's part of the reason the use is restricted. Perhaps because of that there are a lot of criteria which have to be met.

Making vaccines, although very expensive, is less expensive than making these and they are less toxic. There's also the advantage that if people don't get Covid the hospitals won't collapse.
I'm afraid you've got it wrong here.
