The jabs as most people know, do not stop you spreading covid or prevent you catching it, the jabs will in many cases prevent you needing to go in hospital or make the covid symptoms less severe
as for not being able to fly, I've never heard that before,
There is no evidence that air travel can increase the risk of blood clots in people who have received COVID-19 vaccines.

Scary times indeed, at least the person you spoke to is alive, I know someone who has died from covid and someone who spent 6 months in hospital.
