You could have simply said, "No." Then I would have asked, "Why not?"
Fact is, the mRNA vaccines have created a huge number of asymptomatic carriers of the virus. The vaccines do NOT prevent infection in most recipients. These vaccinated people with a Covid-19 infection are creating mutations. These vaccines have generated a false sense of security for humanity and will possibly result in a Great Filter. Already, 49 states have found the mu variant in infected people. You might want to reconsider using the ivermectin as a prophylactic. Cheers!
