Through mid-2025 almost 14 billion doses of covid vaccine have been given, covering almost 6 billion people. The US accounts for about 700 million doses to date. Contrast that with about 500 million doses of all other vaccines (including influenza) being given in the US from 2020. This was the most massive public health vaccination campaign of all time, beating even the 1967 smallpox vaccination campaign. There are four things at work here, and if the physician in the video had half a brain he would realize it, but he is thinking with his political (lizard) brain and not his scientific brain:
Politicization - covid vaccination became a political issue, smallpox did not. And as we've seen, how you view events depends entirely on your political affiliation.
Recency bias - the physician in the video doesn't remember the smallpox campaign because it wasn't yesterday like the covid campaign.
Post hoc ergo propter hoc - "I got the stab and two weeks later ran over my left foot with a lawn mower because of it."
Solipsism - the world is bigger than the people he knows.
