One thing I really don't get is why all the vaccines are so different if they're all supposed to be doing the same thing? And what's in that particular booster that is so amazing compared to the vaccines? Why wasn't there one standard optimised vaccine? Is it because capitalism or just scientific stuff? Why in a worldwide pandemic wasn't there total collaboration for the greater good? And if the booster is that amazing, why us it a booster not a new vaccine altogether? How come it's immediately brilliant for a variant that is apparently about a month old?
Genuinely interested because I've been trying to keep up, but failing miserably....

There's more than one way to kill zombies. Its useful that there are multiple ways to kill zombies cos you might have a hammer to hand even if you couldn't get hold of a saw.
And what's in that particular booster that is so amazing compared to the vaccines?
Boosters are the same as doses 1 and 2. The UK has chosen Pfizer and Moderna because they were performing better than AZ in effectiveness and waning plus AZ followed by Pfizer/Moderna was giving better tcell protection than other mixes.
Why wasn't there one standard optimised vaccine?
Noone knew what was definitely going to work, so there was investment in multiple vaccine programmes in the hope that at least 1 would work. Fortunately several have which gives us a variety of options to chose between. There is a good comparison with the Manhatten project where money was chucked at multiple projects to try and ensure success would happen. Its a bit like spread betting but for medicine. If you back all the horses you are definitely going to win. Thats why there isn't a standardised one. It was just get anything you can as quickly as you can.
Is it because capitalism or just scientific stuff?
See above. No not capitalism directly as such for once.
Why in a worldwide pandemic wasn't there total collaboration for the greater good?
Nationalism and a general desparate panic to 'protect your own' first kicked in. Cooperation largely went out the window when it became apparent that this was slowing procurement of vaccines down. It was 'every man for himself'. There wasn't any international leadership from places who had the power to. Covax hasn't captured the public imagination and domestic political pressure has dominated what individual governments have done. Don't forget world leaders didn't meet each other in person for over a year until Cornwall.
And if the booster is that amazing, why is it a booster not a new vaccine altogether?
The name booster is misleading. It should just be called a third normal primary dose and have done with it. Its confusing people.
New vaccines for specific variants haven't been rolled out because the existing ones were holding up well enough and there wasn't a need to. Omicron, may change that.
How come it's immediately brilliant for a variant that is apparently about a month old?
Its not. Its just that 3 doses seems to produce better antibody and tcell production. The higher levels help to neutralise omicron even those its shaped differently.
Does that help?
