I well remember the 2008 investment conference of Walter Scott in Edinburgh because I got a dose of the shingles. It started with a frightful headache, and then I ended up at the eye doctor as it spread to my eye. Since then many of my friends have suffered this dreadful affliction but I’m delighted to let you know it can now be prevented with a simple vaccination that costs around $200.

According to the latest research one in three people will develop shingles in their lifetime, and the risk of shingles and related complications increases with age. The most common symptom is a painful blistering rash, and people who have suffered it say the pain is excruciating.

The best part of all is that the vaccination is painless – it feels like being stroked with a feather. I am also told it lasts for life. What are you waiting for!
