The other day I recieved a terrifying notification via email, advising me to be alert for evidence of polio in returned travellers. This is due to upheaval in Syria, Pakistan and Afghanistan and a growing global antivaccination sentiment. A crying shame as only a few short years ago we were incredibly close to declaring this planet polio free, an incredible legacy to pass onto our children.
In her day job your author does her best to see as many children as possible immunised against deadly diseases just like this one. Now she will use this little hobby of hers to remind whatever audience she has exactly why vaccinations are so important.
