You just have to laugh, this is from the NHS website last March.

NHS takes action against corona virus fake news
"Health Secretary Matt Hancock said: “Today’s actions are another important step so members of the public can access reliable, accurate health information, which is more crucial than ever as we continue our response to coronavirus.
“These changes will ensure the latest trusted NHS guidance sits at the very top of Google search lists, so people can be reassured they are reading official, up-to-date Government advice.
“Public safety is our top priority and we are harnessing digital tools to reach millions of people on more than 250 conditions they are searching for – including coronavirus – helping tackle misinformation and ensuring the public is well informed to take control of their health.”
Last week the Advertising Standards Authority also took action to ban two face mask adverts which were “likely to cause fear” and made “misleading” claims about their ability to stop the spread of coronavirus.
Tara Donnelly, chief digital officer at NHSX, said: “One of NHSX’s key missions is to ensure that the public are provided with accurate health information so they can be confident they are following official NHS advice.
“By making NHS website content free to use for third party organisations, we are ensuring that more people get NHS advice when they search online rather than from one of the many other sources; some with guidance that isn’t right for the UK, and some that just aren’t right.”
So last March, adverts claiming masks offered protection against Covid was FAKE NEWS and misleading according to the NHS, now we have to wear them to save the planet. I think they're taking the piss.
