I've had every vaccination going since I was born and don't intend to stop now. I still have a scar on my left arm from my very first smallpox vaccination when I was a tiny baby! I had a horrid reaction to a diphtheria 'jag' when I was 10, but that didn't put me off. Science has given us these miracles.
We should be - and I am - grateful that we live in a time when we don't have to dread that our grandchildren will be lost to diphtheria, grow up disabled by polio, blinded by measles, ravaged by TB, suffer learning difficulty through a mother's rubella. I could go on, but I'm sure you'll get my drift...
