Well, that's bad for the show. I like Elsass and his performance - I thought he had a lot of charisma. I don't like recasting, but I don't know if Superman & Lois wants to do a show where one of their kids is gone (they'd almost certainly not kill him off).
The whole thing is really weird to me. The vaccines work. They don't work in terms of stopping the spread, but that wasn't really the point. People were dying and the vaccines can prepare your body to fight without the risk of you dying. Just like the flu shot doesn't keep you from getting the flu - it gives you some protection from that and helps you fight off the virus if you happen to get it.
The problem is that, with the Internet, you can build yourself an echo chamber. You block opinions you don't like, and suddenly all the opinions you see look like yours. Over time, "everyone agrees with you" and the opposition is some sort of crazy minority.
I saw this with the Trump raid online. People saying "most of the country is mad about this" - well, no. Most of the country probably doesn't really care. 1/3 of people didn't vote in the last election. 1/4 didn't even register. Of the 2/3 that did vote, at least half of them wouldn't be angry about it. And of the 1/3 that might, most of them probably don't care enough about Trump to get mad about any kind of persecution. But if you surround yourself with people that are really mad about it, suddenly it seems like everyone is really mad about it.
With vaccines, you block out people that are celebrating the vaccines, and you start following more people who are against them. You find people that say the same things you say, and you start to trust them. So when you hear them say that "healthy young people are dropping dead at sporting events", you trust that even though there's no evidence of that. And the excuses are at least plausible - the pharmaceutical industry probably has had some immoral scandals so maybe they're covering it up to make money. Maybe the corrupt media is in on it. And if you accept the plausible excuses, is it that far to accept the implausible ones about mind control?
People like feeling apart of something. Even if it's stupid, even if it's alienating to people you liked before, even if it's making you sad or angry. Finding people that think like you feels good.
I'm sure Elsass was tricked by something or someone. He probably genuinely believes what he says, and he probably genuinely wants to keep people from doing what he sees is a mistake. But hopefully he's discovered that he's wrong, and hopefully he gets help. And hopefully he gets vaccinated.
Because I think he's a promising actor. He's charismatic and good looking, and people have gone on to great careers after CW work.
