Actually I will say one more thing. If you're under 65, please consider registering as a bone marrow/stem cell donor. You can do it at https://www.dkms.org.uk/ or if you're already a blood donor you can do it through that.This will be my last comment on the subject of boosters, because there is nothing more to say. I feel very strongly about this, for reasons that I'm sure will be obvious.
I'm currently sitting in hospital with my 2 year old daughter. She has monogenic lupus, an autoimmune condition that causes her body to attack itself. We've nearly lost her 4 times in the last 18 month, most recently in September when she had a stroke. To manage this she has to have 6 monthly chemotherapy, leaving her with a severely weakened immune system.
In ordinary times this is a worry, with the infection levels where they currently are it's terrifying. In order to give her some protection she has a monthly infusion of immunoglobulin therapy, which is what we're doing today. It takes 6 hours, and for the next week she'll have high temperatures and an upset stomach. She's still at an extremely high risk if she catches covid.
In order to have any semblance of a normal life going forward the only cure is a stem cell transplant, currently scheduled for the first half of this year. If covid overwhelms the NHS, or if she becomes ill, that will be pushed back, and the older she gets the less likely it will work. She may even become so ill she needs a kidney or liver transplant first, making a stem cell transplant even less likely to succeed.
You're right that the booster won't 100% stop you catching and passing on covid, but it will reduce transmission, both of this and future variants. If everyone has the booster, then my daughter has a much better chance of getting to that stem cell transplant.
So I'm genuinely begging you, if you don't feel you need the booster for yourself, then consider doing it for her.
