I don’t think that’s quite accurate. Close though.
MAbs will kill off the virus before your own immune system can learn to make its own antibodies against the virus. So you won’t gain natural immunity from that infection.
To train your immune system you will either need to let the infection run untreated, with the risks that go with that, or get vaccinated.
Not true. My husband has covid, got the MCAs and later was tested, he did have very strong antibodies
