Hopefully temporary, new strains not expected to impact vaccine efficacy...

Itís ALWAYS temporary until it isnít. Anything that pushes the timeframe back is just adding to the hurt.

I hope new strains are close enough to the first that the vaccine will work against it too.

They usually are, odds of a random mutation getting around a vaccine at this point are slim, that would require a lot of random genetic luck since there's no evolutionary pressure to drive that now. Once vaccines are deployed on a large scale, then odds increase slightly that it might mutate around the vaccine.

Mutations are quite random, a mutation which provides a specific benefit in the face of evolutionary pressure does not necessarily retain all of the bug's original features, or result in an overall "improved" version. It might, and often does, result in a tradeoff. Very rough analogy: take a B-52, cost-effective and carries tons of bombs with a long range... but if the enemy deploys sophisticated air defense systems you might need stealth, supersonic cruise at low altitude, and counter-measures. By the time you make those adaptions, you probably had to sacrifice a whole lot of payload.

Also with covid, natural selection favors spreading. It does not favor severe illness. So it could drift away to become milder over time. In fact severe illness is probably an evolutionary dead-end with humans because that causes people to do things to mitigate spread (unlike animals). There are coronaviruses which are part of the spectrum of bugs which cause the common cold... those we just tolerate because they're a minor nuisance, not a real health risk.

But even mutation around a vaccine's probably not a catastrophe, vaccine might still provide partial protection, bug might become less contagious or less dangerous, etc. Plus we can tweak the vaccines, especially the mRNA ones. Worst case, probably ends up like the flu shot, with period adjustments to an annual vaccine.

The experts said this strain has been circulating for about 3 months. Nothing to see here. Some of you are worse than third grade journalists with your sensatiolism.

Would you consider the sensationalists to be the ones here reporting on the travel restrictions, or the ones actually restricting travel?

Indeed it has:

TORONTO ó Canada is banning passenger flights from the UK in a bid to block a new strain of coronavirus sweeping across southern England.

A person familiar with the matter confirmed the development on condition of anonymity as they were not authorized to speak publicly ahead of an announcement.

Additional EU nations have also joined in.

At least 10 European countries banned travel from the UK on Sunday amid concern over a more infectious new strain of Covid-19 in Britain, with France calling a halt to freight transport across the English Channel. Germany, France, Italy, Belgium, Austria, Ireland and the Netherlands were among the first countries to bar people coming from the UK after a sharp rise in coronavirus cases. The move by Paris to impose a 48-hour block on people and truck-borne freight coming into France from Britain from Monday prompted the closure of transport services across the English Channel, notably between Dover and Calais. It raised the prospect of crippling delays on the UKís main freight link with the EU, which usually handles up to 10,000 trucks a day.
