Realistically most countries are going to require a vaccine to get a visa so the airline policy won't matter.
There's already a fair bit of historic precedent on this with yellow fever and so on.

True, but some key differences in the comparison. The vaccine for yellow fever is widely acknowledged to be both safe, and effective (I'm aware that nothing medically can be guaranteed 100% safe) but compare this to what we know at the moment of a covid-19 vaccine...?

The mortality rate for yellow fever is widely acknowledged to range quite significantly above covid, and can be really dangerously high in some areas & circumstances. Again, comparing this to what we know about covid,..

I’ve read about the yellow fever vaccine but still I’m struggling to find any info to state that it is a requirement for entry rather than simply being a recommendation.

There were more ages ago so a precedent.

For sure large numbers of countries will demand it for entry. Thailand will for sure, likely Philippines, Indonesia.
Lots have pretty much stated that already.

We have to stop flying for a year.
At the moment they think they hold the cards, we want to travel.

Won't happen. People want to travel, even more so after a year of having it taken from them.
That includes me.
I've been trapped in the UK for the longest period of time in 12 years and desperate to get out.
But without travel i cant work and wont have any work.

People are going to travel no matter what. Most people will be vaccinated voluntarily anyway so they really wont see it as an issue.

As i said, lots of countries are likely to demand vaccination so airline policy is unlikely to be an issue.

The Ashes (cricket) are in Australia next winter and the Barmy Army facebook page is full of people saying they will be first in line for a vaccine if it means they can go down under to watch. Same with lots of sports fans, isn't the Olympics next year? The fact that the vaccine won't stop them getting it and may not even stop them transmitting if they do get it seems to be neither here nor there.

So no use hoping people will not travel, they will be only too happy to have a potentially unsafe and probably pretty ineffective vaccine just so they can get away on holiday or work.

Society’s default position is that men are bad and to be shamed.

You never see a male role model anymore or anything positive about a man.

And men, if they are portrayed in the media at all, it’s as a bumbling fool / bad / toxic.

The Gillette advert is a case in point.

If a man gets a kick in the balls by a woman it’s funny, reverse the genders and it’s abuse.

Don’t even get me started on the family court system.

So yeah. Some of us have noticed it. And some women are noticing that more than a few men are checking out / are no longer available on societally “normal” terms.. aka marriage.

If I'm not mistaken, I think Qantas was the vile airline that humiliated a perfectly innocent man who just happened to be seated next to children that weren't his - they asked him to move so a woman (who wasn't their mother) could be sat there instead. So the implication was that ALL men are paedophilic sexual predators.
