The Moderna vaccine seems to have the fewest side effects. I and everyone at my work received it and no one had any problems. I’d like to get the booster now but I’m in good health so need to wait my turn until after the nursing home patients, etc. get it.
Even though I work in healthcare we have a few people at my work who chose not to get vaccinated. One of them died of Covid last week. Several vaccinated people have caught Covid and said it’s a rough experience, but none of them have needed a hospital.
Wife and I have had the Moderna, and that is exactly our experience. Light side effects, we know one person who did get COVID after being vaccinated, and he needed no medical treatment. From what we’ve seen, the Moderna has worked pretty much as intended on everyone we know that received it. They claim an 85% reduction in cases needing medical treatment and near 100% reduction in deaths from COVID. My mother in law died from COVID June of 2020, before vaccines were available.
