When in doubt, read information from the Mayo Clinic. Here’s a primer on how the different vaccines work. For those who are concerned about the RNA in the mRNA vaccines, this article will definitely sort it out. It’s technical, but it’s correct. We have more than a year’s worth of safety data on over 1.5 billion people who have been vaccinated, and we can say for sure that these vaccines are many orders of magnitude safer than the disease itself. ~1/100 unvaccinated people could die from COVID (more if health systems are overwhelmed), and 20% or more of those infected will have serious health sequelae from the illness (like long-COVID or permanent organ damage). Perhaps 1/250,000 or fewer will have a serious vaccine reaction. Most of these reactions are treatable. The clotting and reports of myocarditis after vaccination are far less frequent than the clotting and myocarditis seen with the actual disease. This is not a flu-like illness that folks can easily recover from. It’s a frequently fatal, highly-contagious clotting disease that also causes multi-system organ damage and lung-scarring pneumonia. I would actively encourage everyone to get vaccinated as soon as possible–the Delta variant will take hold by fall and the fence-sitters could be in for a difficult end-of-year.
