Not necessarily. I contracted the Delta variant last week despite being fully vaccinated with Moderna and taking ivermectin prophylactically for months...
Maybe Ivermectin doesn’t interact with the magic vaccines very well.
Obesity, vitamin D deficiency, and diabetes, also thrive on the virus, and it’s variants.
Also, taking zinc in conjunction with Ivermectin is recommended.
I didn’t take ivermectin until the first onset of symptoms. I was sick for 24 hours, and then I felt terrific.
