"It's easier to get one vaccine a year than to check 50 times (to be generous) a year."
This isn't a replacement, you still have to check even if you're vaccinated.
"Also that would only tell you that you have a tick and then you need to check again that you see the red swelling to know you are infected."
Wrong. The red swelling does no occur in all cases. You can be infected without it. Generally, one should have the tick examined to see how long it was attached (if they don't know).
"Then you need to get the antibiotics and then you need to hope that works."
You would need to do this even if you have the vaccine (assuming the tick was attached for longer than 24 hours or there's reason to believe it was interrupted from a previous meal and then but you - testing the tick will tell).
Your "refutations" don't actually contradict anything I said, I just don't dump everything that comes to mind or that could come to mind into every HN comment I write.
Prevention is always better than a cure, so yes you still have to check. Yes I know the Erythema is optional. Yes I know a vaccine isn't 100% effective. I'm actually a licensed veterinarian you are trying to mansplain here...
