I am 71 and I am volunteering at a Vaccine Centre. Masks, gloves and hand sanitiser are supplied and we do different things each time we volunteer. We might be managing the queues outside or directing people to the waiting room and ensuring they stay for 15 minutes after the vaccination. It has given me a new lease of life as I was very bored with the lockdown and have begun to feel useful again. However, I do not have anyone vulnerable at home to worry about but I can understand how your husband feels, I think he just wants to feel like he is helping. I feel that I could pick the virus up anywhere, in the supermarket, in the newsagents. I don't think there is any bigger risk at the Vaccination Centre.
