People don't seem to be able to get away from the fear of a doomsday variant. I posted some quotes from one of the creators of the AZ vaccine on this thread
Coronavirus (2021) thread
Basically, it's extremely unlikely that there will be a variant that can escape vaccines because to do so, it would require such a huge change to the spike protein as to make the virus itself non-functional.
Unfortunately, the media love the idea of a variant bogeyman as it allows them to scream hysterical headlines and government seem to like them too as it aligns with their published objective of 'increase sense of personal fear'. Hopefully over time some perspective will prevail because variants will never go away and we can't base all policy on a hypothetical variant. Labour were talking more nonsense when they demanded that border policy 'in case we allow a new variant in'. There will ALWAYS be new variants and so this just isn't a credible policy.
