This whole pandemic has fued with our critical thinking. If you rewound to 2019 and had a story about a flu vaccine that had been rushed through we'd all be asking questions.

Just because there is a huge necessity to rush approval and dispersement doesn't mean the risks of unknown side effects are diminished. Lengthy approval processes and clinical trials are in place for a reason. And when you administer this vaccine to billions of people you are almost certain to see side effects. That's just simple science.
