Ryanair are selling holidays for the post vaccination period - looks like by Easter things my be under control
A bit wildly over optimistic.
The UK is stretching the gap between Dose 1 & Dose 2 to 12 weeks. So, even if you are in the over 65 group- expect a jab Feb/March - second dose May/June - give it another 3 weeks for full effacy.
We are looking at August / September at the very earliest before any significant impact on leisure travel.
That's without any issues with production or distribution.
The Ryanair" jab & go" adverts completely absurd IMHO. You need two jabs- in the UK a gap of 12 weeks- then wait for effect- so you can't just jab and go can you(?)
