Funny you should say that Keith.....
"The Madrid region announced on Friday that it would be bringing forward the administration of the second shot of the Oxford-AstraZeneca Covid-19 vaccine for the 60-69 group, given a rise in the number of cases of the so-called “delta” variant of the coronavirus that was first detected in India."
And the Indian variant numbers are rising right across Spain so I suspect that those of us in that group will get our second jab sooner. Mine is scheduled for the 2nd August at the moment.
