The difference though Ian is you don't get forcibly injected to drive on the left.
My son's half brother had his second jab (he's 18) a couple of weeks ago, the other day he was rushed to hospital and was diagnosed with type 1 diabetes, the only symptoms he'd seen had started since the second jab (thirst, tired feeling), so now he has to inject etc. for life - connected to the vaccine ? - who knows, no-one is interested in finding out, they merely say "It doesn't matter how he developed it, he has it and it needs to be managed", it seems very coincidental but maybe it is, or maybe it isn't.
