If you fancy researching population stats and doing the maths:
- an estimated 88% of the population has now had at least one dose of a vaccine
- an estimated 70.3 per cent of the population has had both doses of a vaccine, you become eligible for a second 8 weeks after the first
- Pfizer was licensed first in December, and the top priority groups were over 75s and healthcare workers. I *think* most over 75s got Pfizer, and all healthcare professionals I've heard talk about it got Pfizer
- Astra Zeneca vaccination started in Jan/Feb and were then given to over 40s and 18-65 year olds classed as clinically extremely vulnerable, plus people with assorted other health conditions than made them vunerable. My parents (early 70s) were given AZ, and they got their first jab in Feb, Pfizer didn't seem to be used much for a couple of months after that
- Pfizer and now Moderna are the only vaccines currently offered to under 40s, and to a small percentage of people who couldn't have the AZ one, Vaccination of the wider population aged under 40 started in June
- Pfizer is/will be offered to 12-18 year olds with certain health conditions
The others aren't in general use yet, as far as I know, only trials. I've read that J&J is most likely to be the one offered as a booster to the most vulnerable people in the autumn. Which is a bit of a shame, I would have thought that giving a mRNA vaccine as a booster could be a plan, but they're mostly reserved for younger people. They're being a little bit quiet at the moment about comparing and contrasting vaccines, which isn't a surprise while the vaccination drive is still going on and they don't want to put anyone off. If you're over 40 you'll almost certainly get AZ, if you're under 40 you'll almost certainly get Pfizer or Moderna.
Anyway, things are looking a bit more hopeful right now. The sharp increase in cases hasn't continued, case numbers now seem to be dropping (although hospitalisations and deaths are going up, likely based on infections 2-3 weeks ago). I'd like to be more hopeful about vaccines, but I wouldn't rule out the schools being on summer break and a lot of people being away on holiday (so not crammed into town centre shops and workplaces) having a major effect too. The numbers of covid tests have also noticeably gone down, not entirely sure why - fewer people with symptoms, people not wanting a test result to ruin their holiday, or less of the LFT monitoring that was done around schools and workplaces. There's another variant being monitored at the moment too, one that was first detected in Columbia and has mostly been seen in the US to date.
