“I had tried to suggest that one of the reasons why France had a slow vaccine take up was because they had the highest immigrant population in Europe.
I was told that that view was nuts.”
No you were not, it was pointed out to you that the premise for your assertion was wrong, namely, that France has the highest immigrant population. It doesn’t, in fact it has the fourth largest population of immigrants with Spain almost equal footing.
“In absolute terms, the largest numbers of non-nationals living in the EU Member States on 1 January 2018 were found in Germany (9.7 million persons), the United Kingdom (6.3 million), Italy (5.1 million), France (4.7 million) and Spain (4.6 million).”
The wiki article on European immigration gives more nuance with the UK and Germany having higher Immigrants as percentage of national population as does this data from OECD.org. So your reaoning that because France has the highest immigrant population they have low vaccine uptake does not work. If you look at the percentage of total population immigrants comprise of a country you will see France is about middle ground with UK and Ireland higher, where vaccine uptake has been highest.
This is leg work you should have done before you post Michael. Instead you leave it to others to do it for you. If you are going to state x is because of y at least make the effort to ensure that your assertion that ‘fact y is correct’ is indeed correct before you post.
