According to Dr. Scott Segal, chair of anesthesiology at Wake Forest Baptist Health in Winston-Salem, North Carolina, even that may not be enough.

“If you put three or four masks on, it’s going to filter better because it’s more layers of cloth,”

Segal told NBC News.

That was an interesting read. I can't comment on any of the virology stuff but it did strike me that all those scientists in favour of doing "Gain-of-function" research are defending their livelihood.....
It also reminded me of this post on Jo Nova's site:
https://joannenova.com.au/2020/05/is-coronavirus-man-made-the-bat-virus-it-evolved-from-appears-to-be-faked/
This claims that the claimed natural source for the virus has features which look man-made. Again, I can't comment and I don't want to disappear down the rabbit hole of the work which led to that thread!

When a hypocritical breach of health rules is no damage to career progress:

Catherine Calderwood given senior NHS role at Golden Jubilee

The Scottish government's former chief medical officer, who quit after breaking lockdown rules, has been given a new senior post in the NHS.

Catherine Calderwood resigned after it emerged she had breached travel restrictions to visit a second home.

She has now been appointed as national clinical director of the new Centre for Sustainable Delivery at the Golden Jubilee hospital in Clydebank.

It is believed the role comes with a salary of £85,000 to £112,000.

Dr Calderwood became well-known across the country after she fronted TV and radio adverts urging the public to stay at home to save lives and protect the NHS....

She only did it because she honestly believed she wouldn't get caught.

Mark, should a person’s life be blighted ever more for an error of judgement? Catherine Calderwood clearly has organisational and leadership skills. Should society be deprived of those skills? Some people learn from their mistakes. Perhaps CC is one of those.

Tomo. Suggest you read about her qualifications before spouting off at full cock. It seems clear from the manner of her leaving that she was valued by Scotland’s First Minister and that after ten months she has again been offered a position befitting her apparent talents. You presumably would damn her forever?

Tomo seems like your axe grinds more against the SNP than Catherine Calderwood.

Regarding Catherine Calderwood, I think it's an emotive and complex issue. No I don't think she should be damned for ever for making a mistake, though it was an egregious and hypocritical failing in my view, more than a simple mistake or (that catch-all deployed when people are caught out) an error of judgment.

For all that, rightly or wrongly I saw her re-engagement by the NHS as all-too typical of what seems to happen very frequently in the public sector (and at football clubs!) with a revolving-door of exits by people who have failed or otherwise messed up (often with a golden goodbye, though I don't know if there was one in this case) followed shortly by another public sector door opening up and another handsomely paid and pensioned position becoming available.

Whether Mrs Calderwood is the right person for the job, whether the public should or should not be denied her "skills", whether she should have served more time in the sin bin I simply don't know. I suppose only time will tell - if she performs admirably, and justifies her salary without further mistakes, then yes, perhaps it will be a good appointment. If not, it won't be. I think I need to think about it a bit more deeply, but at the time I just wanted to share a story I thought might be of interest in the context of the Covid thread.

Fair play to Larry Elliott for writing a piece I never thought would see the light of day in the Guardian (and fair play, too, to the Guardian for publishing it):

EU Covid incompetence leaves governments wanting vaccines, not excuses

I've had my first jab. Went very smoothly. The sooner it's in arms, the less likely the EU can get their hands on it.

Very surprising article Mark! I'm sure that the feelings will ware off.

Has anyone who has had the vaccine felt poorly for the next few days? I had my AstraZenica vaccination last week, had a very sore arm and felt very low for at least three days. Subsequently I discovered that at least four other vaccinated people who had had COVID-19 also felt ill, whereas their spouses, like mine, who hadn’t had the disease in its symptomatic form, were not so affected. This relationship occurred regardless of which vaccine was administered.

AK; my daughter had a similar experience. Her arm became stiff and sore for a few days and she felt a little off-colour.
She had the virus back in March and regular tests since had shown a high level of antibodies so she asked whether the jab might not provoke a bit of an over-reaction. She was told that she might get local tenderness, even swelling, and possibly some mild symptoms, for that reason.
So your reaction to the jab might be down to you still carrying antibodies from your original infection.

On the overall vaccine issue, I read an article last weekend which gave a bit of background. Apparently, not long after the Brexit vote, someone started to do a bit of forward thinking to identify areas of the economy which should be nurtured to boost future growth. Medecines & pharmaceuticals was one such area so there has been on-going support which facilitated the effort to construct a vaccine programme.
The Valneva vaccine is a case in point. The govt got into talks with them back in July of last year and agreed to fund the expansion of their production facilities as well as ordering 60 million doses which are due to start arriving soon. By the end of last month the firm's contacts with the EU had amounted to some preliminary discussions which were inconclusive.
I found that very encouraging as it is what we should be able to expect of govt. They deserve much credit.
It will be very interesting to read a full account of what went on, once things settle down.

MikeHig. I’m sure you are correct. I wasn’t surprised by my reaction, having anticipated it, using the same logic you have used. I’m actually more intrigued by the lack of reaction (other than sore arms) of the spouses of former Covid sufferers. In my wife’s case, I cannot imagine how she could have avoided becoming infected when I did. Either she was immune carrying antibodies from an earlier coronavirus cold or she caught COVID-19 but was asymptomatic. But then why did she not react to the vaccine as I did? Then I remembered that there was a link between the severity of the illness and the amount of antibody production. So I don’t believe a lack of any reaction to the vaccine can be used as an indicator of whether an individual had the infection.

I also agree with you about the Government’s response to COVID-19. Johnson and his cohorts have come in for considerable stick. This fracas with the EU has slowly revealed just how foresighted some people have been and the Government should get considerable credit for appointing them, sticking with them when brickbats have been thrown, and, in fact, not bragging about those achievements. I never would have guessed that, as a committed lefty, I would be praising the Conservatives and Johnson, but I do.

Corbyn arrested.

About time.

In Corbyn's case, I wonder if a plea of insanity would help?

Gotta love the Graun: they tag him as a "climate change sceptic" front and centre in an article about anti-vaxxing. Maybe they've been conditioned by all the hype trying to conflate covid and climate change.

AK; I have heard of lots of examples of apparent immunity like your wife has displayed - I expect you have too. There seem to be many cases where, for example, 2 out of 3 flatmates get the bug but not the third. A good friend's son did not catch it even though his fiancee (living with him) did - he did not test positive when she did, nor did he have antibodies when tested later.
As you say, there may indeed be some latent immunity from previous infections. A while back there was that study which found that samples from people who had the original SARS 17 years ago showed a strong T-cell response.
There's still an awful lot to learn.
