It's never going to work, and wont be easy to enforce so they may as well wind things back to a senisble and managable level.
*deep breath and puts on his explaining cap*
mRNA technology has been around over a decade and as a technology already passed human testing trials, however wasn't widely needed. It was actually being tested for personalised drug treatment (for example cancer treatment).
When the initial SARS virus hit (ended 2004), and them MERS followed it up (in 2012), experts genomically sequenced the virus at that time, and had been working on vaccinations for that.
As such when Covid (SARS-Cov2) reared its ugly head, a lot of research and understanding was already there on the base modelling for the disease/virus, and its makeup. The gamechanger however was SARS-Cov2 caused Coronavirus disease.
Due to the rapid spread of SARS-Cov2, there was worldwide collaboration from leading infectious disease experts around the world (mostly whilst the rest of the world went into lockdown).
As a result there was a shitload of existing data, plus a lot of very clever minds, and near instant genomic sequencing, that lead to a massive research effort the world over, in order to best defence against Coronavirus.
Regarding the boosters, variants (mutations) do occur. When a virus mutates sometimes it becomes stronger in some areas, but weaker in others. There are heaps of covid mutations, however you really only hear about them when they become "variants of concern". VOCs are determined by specific viral aspects, including vaccine efficacy, ease of transfer between hosts, and severity of infection.
In some cases mutations won't be noticed, or might impact two people differently.
In example the original covid variants had a specific set of functions and symptoms. Vaccines defended against that.
In the example of Delta, it was a mutation after most vaccines were administered, hence a booster. It's a real piece of work, which can do serious damage.
However by comparison Omicron when it mutated became more vaccine resistant, but the offshoot was that it was far less damaging.
If Omicron was the next and only mutation after the original variant, no booster would have been required. Booster covered Delta Plus and Lambda variants (both really nasty - infact Delta Plus we are really lucky to avoid) incase they ever came out here.
Therein lies the point that most anti vaxxers completely miss. The vaccine is not about stopping you getting it, it's about muting the viruses ability to replicate, and cause you serious harm.
It's about not making you end up in ICU taking up a hospital bed, when you could be at home recovering instead.
Out of interest, are those vaccinated you know still alive after copping Covid? How many UNVACCINATED people do you know that have confirmed Covid (non Omicron variant)?
Must be... I mean the majority of people in ICU have Delta variant and are unvaccinated, so clearly the vaccine is not working.
Yes I'm being sarcastic.
