I visited a Moderna vacinated friend at her going away party 2 weeks ago and felt icky with a runny nose until I took Ivermectin again
I believe I took a smaller dose of the apple flavored horse pasted. My aches and runny nose were gone within 24 hours which were similar results when I had taken a slighting larger dose a month prior.
This is my anecdotal experience. However it matches up with what the doctors are saying about shedding or transmitting. She had been one of the first to get the Moderna vaccine because she has been getting cancer treatments.
