Sir, – It is true, as Sam Bowman writes, that the Common Travel Area gives British and Irish citizens the right to travel between the two countries without a passport, but don't try flying from London to Dublin without one ("The UK government should consider offering vaccines to the Republic", Opinion & Analysis, February 2nd).
The gardaí at immigration control insist on seeing your passport to ensure that you are entitled to travel without one.
I wish Sam Bowman luck with his proposed “Common Immunity Area”. – Yours, etc,
Dr JOHN
