Covidiot alert!
Of course covidiot. People who die within 14 days of getting the gene vaccines are counted as unvaccinated deaths.
So, why does a booster help against Omicron, when 2 doses don't?
Well, you asked: https://www.bbc.com/news/health-59639973
And now you know.
You're welcome.
From the BBC:
Vaccines are more like a school - a safer environment to further your immune system's Covid education.
The first dose is the primary school education that nails the fundamentals.
Your second and third doses are comparable to sending your immune system to secondary school and then university to dramatically deepen its understanding. It's not just repeating primary school over and over.
"The immune system is left with a richer knowledge and understanding of the virus," said Prof Jonathan Ball, a virologist from the University of Nottingham.
He said for all the talk of the dastardly tricks of Omicron, a highly-trained immune system is "an incredibly difficult and hostile environment" for the virus and its variants.
Antibodies are a major beneficiary of this education.
These are the sticky proteins that attach themselves to the outside of the coronavirus. Neutralising antibodies can gum up the virus so it can't invade your cells. Others sit there as the biological equivalent of a flashing neon sign spelling out "kill this virus".
A flurry of laboratory studies and real world data showed the neutralising antibodies you have after two doses of a Covid vaccine were far less effective against Omicron.
Prof Danny Altmann, an immunologist from Imperial College London, said you were left with "absolutely zilch" and were a "sitting duck for infection".
So back to school.
Every dose of the vaccine triggers another round of antibody evolution within the immune system. It seeks out better antibodies that attach themselves more firmly to the virus. It's a process called affinity maturation.
"Your antibodies are a better fit as time goes on, they are getting fancier and more sophisticated," said Prof Altmann.
If the antibodies are able to bind more tightly to the coronavirus then it will be harder for Omicron's mutations to help it wriggle free. And while the new variant is heavily mutated, it is still the same fundamental virus and has parts that have not changed at all.
Further rounds of vaccination also lead to the immune system broadening its antibody repertoire as it finds new ways of attacking the virus.

@paul-a-roberts saidRight on, Paul.
Let's hope that she gets well soon, and her mild symptoms are all she gets thanks to her vaccinations.

Or, if they do, they pick out the information that suits them, leaving all context aside.
So, a sentence like: “Don’t eat too many chips, they can make you fat; it’s unhealthy to eat too many carbs.”
Gets translated in their mind as: “Eat many carbs. Healthy.”
@metal-brain saidAccording to figures released by the UK government via the Office for National Statistics, people who are triple vaxxed are 4.5 times more likely to test positive for Omicron than those who are unvaccinated.
