'Other antibiotics like penicillin act on invading bacteria, and those bacteria can then counter the antibiotics by developing beta-lactamase enzymes to become resistant to antibiotics.

On the other hand, ivermectin works on the host’s cells. That means no viral resistance happens even if a person uses ivermectin for a long time. That is why ivermectin can be used for prevention for a long time.

Even if the SARS-CoV-2 mutates to other variants, the ivermectin will still work!

The other good news is that ivermectin is not only specific to SARS-CoV-2 but also has antiviral activity against other nasty viruses.'
