When I posted this on the 6th Wales was 10.1% ahead of England in terms of first jabs and 4.2% behind in terms of second.
As of the 11th of June Wales has managed 9.4% more first jabs than England while is 3.4% behind England in terms of second jabs.
It's not a race, there are many different factors at play and it's dependent on people coming forward especially if they think they've been missed. In terms of the Delta Variant the protection is much greater after 2nd jabs.
