I'm a microbiologist and those predictions are likely wrong, in my professional opinion. Things definitely won't be "new normal" in Western Europe unless the vaccination checks are very widespread for public events, which could be the case but it will take the political will to implement it.In the US the current predictions are by summer things should be starting to get back to normal.
Also, the 100M jabs in 100 days is not a good implementation plan, but I'm not a politician, thankfully.
