At 75, I've volunteered for a Covid vaccine trial. It could set people free

There’s a 50% chance that this week I was injected with a vaccine designed to protect me from Covid-19. If not, I got the saltwater placebo instead. I won’t know until the study ends in 13 months, which is a shame. It would be nice to walk the streets without looking balefully around me at young people not wearing masks and thinking: I’m 75, this virus kills people my age. It killed my chum Mike Pentelow, who was having a lot of fun in his retirement, writing books with titles such as A Pub Crawl Through History, and Mike was a year younger than me. Perhaps he’s the reason I volunteered to be a guinea pig for one of the companies working on a vaccine.
