I think it means you are 70% less likely to get it than an unvaccinated and covid naïve person
But of course you can only catch it once (within a short time at least) so the covid naïve person likely catches pretty easily with a highly infectious virus. If cases remain high, 70% is really very little protection, especially against superspreader events when really the unvaccinated were almost guaranteed to get it. If the prevalence is 1% and you go a restaurant/pub every day, I can't see 70% being anywhere near enough, even if it doesn't wane.
Agreed.
With 70% protection you are 3x more likely to catch it than when we had 90% protection.
An un-vaxxed person was 10x more likely to catch it then.
I'm not sure Omicron gives a shit about immunity from Delta infection, and any other variant is probably too old to be useful. We need those fresh surging antibodies.
And it's about to be way more prevalent than it has ever been.
Soon it will be everywhere indoors that we go.
Work, school, pantomime, pub, shop, sister in law's house on Christmas Day, everywhere.
Previously our best protection was that it wasn't everywhere.
