General   (General discussion, talk about anything.)

If you watched the briefing, and the link is still there above, they explain that the Covid-19 vaccines being used, are the same vaccine as what was originally developed for Covid-19, when it was first found, and it is known as the Wuhan virus, and viruses mutate all the time, but if a mutation alters the virus enough, then it might affect the way that the original vaccine works, making it less effective, then it becomes a variant of concern, and so far there have been four variants of concern, beta, gamma, delta and omicron, so the variants of the virus, then have a slight mismatch to the original vaccine, but it was found that even with these mismatches, the vaccine still worked against the first three variants, to the extent that the vaccine did not require to be 'tweaked' to match the variants, but with this new variant 'omicron', it is not yet known if the vaccine will be any less effective against this new variant.

When the vaccine is beginning to be less effective against the variants, then the scientists will alter (tweak) the vaccine to match it to the emerging 'dominant' variants, this happens with floo every year, every year the flu vaccine, vaccinates against the three strains of floo, which the scientists think will be the most prevalent during the following winter flu season, and sometimes they get it wrong.

So they might alter the Covid vaccine, or they might not, it will depend on the science of the thing, but the booster shot everyone is getting at present, is the same vaccine, which there as been from the start, it is just boosting your immune system, and I think the scientists will just have to wait and see what happens with the virus, it might burn it's self out, because it cannot find enough 'hosts' to sustain it, because of immunisation, or it might not.
