That is true. In the health care workers prophylactic studies in India where they gave dose 1 then 72 hours later gave dose 2 they noticed that if people forgot their second dose they had no benefit.

I'm doubtful that one dose a month would accomplish much protection because the half life of IVM is 18 hours.
