There once was a very wise old rooster
Who decided to go for his Covid booster.
, But when he got there
A young nurse named Claire
Said, “this booster is not meant for you rooster!”

(I went for my Covid booster yesterday and, strange to say, not a rooster was in sight.

To be serious for a moment, if you are eligible for a booster, and have not yet had it, I would urge you to do so. The vaccine is helping to keep us all safe. Yes it doesn’t offer absolute protection, but we are now in a much better position than we where prior to the introduction of Covid vaccines).
