Got my seasonal flu vaccine yesterday.

A very slick operation at the GP where hundreds of people classified as vulnerable to an airborne respiratory disease (for various reasons) are swiftly pointed to one of many rooms where someone checks you're the right person, stabs you, and out the other door you go.

An airborne respiratory disease dangerous enough to this group of people they need an annual vaccine against it.

I was the only person there wearing a mask.
Not even the staff.
