Earlier quoted context omitted.
In the short amount of time people have been taking these vaccines, how much more data than a few months could they really be looking at, seriously ?
They're looking at a century's worth of other vaccines and noting that the side effects present early on, not years later. The stuff in vaccines gets broken down or excreted by the body; it doesn't linger in your system for years. mRNA, for example, breaks down in minutes/hours.
When we know more about the long term, then people will be more happy to take it?
