How to advertise for a flu shot

Here is Piers Morgan, the CNN anchor getting the flu shot on live TV to demonstrate that it is harmless.

Here is the same hero , doing an about turn about 10 days later.

So at least we have one person educated, real time. Need I say anything more?

PS: I’ve been wanting to start posting about vaccines here, but I tend to put too much time and effort into my posts, so have been holding off, when I can afford to spend the time. But this was a nice bolt from the blue. What better advertisement do you need for the flu shot?
