Do you realize that all viruses mutate? The flu is a perfect example, and we consider the current flu vaccines effective when they have 40-60% efficacy, and that saves a great many deaths. The flu virus was isolated in 1933 and the first vaccines were in use in the 1940s. They have gone through many iterations since.
The fear-mongering concerns that keep people from vaccinations is what is killing us by the 100s of thousands and helping to increase the speed of mutated variants. The scientific breakthroughs that have led to the current vaccines is nothing short of astonishing and should be applauded for their remarkable efficacy and safety.
BTW, for those taking Ivermectin, you should know that the side effects of this drug which include: a variety of G.I. issues, drowsiness, itching, rashes, hypotension, fluid retention, headaches, loss of bladder or bowel control, seizures, and more -- including lower testosterone and impaired sperm mobility.
The first paper claiming excellent results for Ivermectin for the treatment or prevention of Covid was found to be very seriously flawed by plagiarism and data manipulation and was withdrawn from publications. Before it was removed, the supposed findings took off and was repeatedly cited, spurring other research, much of which had serious concerns about sample size, outright fraud, and flawed statistical information.
Next came the conspiracy theories to present these challenges as efforts by big pharmaceutical companies to suppress the information because it's a cheap drug. We are drowning in pseudoscientific misinformation. Currently, the overall reliable evidence does NOT support using this medication to prevent or treat Covid.
