You said its completely safe what's frankly untrue.
We dont routinely take 3 of the same vaccines a year. So I would guess you cant compare apples to oranges.
But we do know some people have had life threatening complications due to the vaccine. So its not completely safe as you said.
Do you pipe up in the same way when people talk about taking aspirin, or going in for major surgery? You’re arguing semantics - the vaccine is extremely safe. Spreading your anxieties about its safety isn’t helping anyone.
