My abdomen lurched once I first heard about Omicron, a brand new, extremely mutated variant of Covid-19 that led, this week, to the reintroduction of masks and a worry of extra restrictions to come back. So how fearful ought to we be?
Properly, after contacting one of many UK’s main consultants, I believe that whereas there may be purpose to proceed being cautious, as a result of it’s at the moment a worrying variant, an important factor we will all do is get the booster jab, which provides the reassurance of actual safety.
Robin Shattock, who’s a professor of mucosal an infection and immunity at Imperial Faculty London, has spent a long time engaged on vaccines towards a variety of infectious ailments, together with, most lately, Covid-19.
He instructed me that though he thinks Omicron might certainly develop into extremely infectious, for him an important query to reply is: what affect will the brand new pressure have on charges of hospitalisation and dying?
I lately needed to inform a buddy, who has chosen to not get vaccinated, that he’s now not welcome to a small social gathering I’ve organised subsequent week
Though the info popping out of South Africa, the place it was first detected, counsel Omicron is extremely infectious, up to now it doesn’t appear to be extra lethal than different variants, though we received’t know for certain for a number of weeks.
The opposite huge query is whether or not our present vaccines will proceed to guard us.
Whereas Omicron may be very completely different from the Alpha variant and the unique pressure that got here out of Wuhan two years in the past, Professor Shattock thinks that being vaccinated will nonetheless give our immune methods the sting.
As he explains: ‘In case your immune system has seen an analogous variant, it already has a head begin to make an tailored response to a brand new one.’
If it seems Omicron is healthier at evading our immune system, Professor Shattock says producers will be capable to modify their vaccines. As this might take a few months, and doubtless received’t be rolled out a lot earlier than April, he says: ‘If you happen to want a booster, don’t watch for an up to date model of the vaccine; your best choice is to get what’s out there now.’
I had my booster final week and the remainder of my household are lining as much as have theirs as quickly as attainable. I used to be happy that, having beforehand had two AstraZeneca jabs, this time I had the Pfizer.
The 2 vaccines work in barely other ways, with research suggesting that the AstraZeneca produces a bigger and longer lasting T-cell response (these are the immune cells that search out and destroy viruses), whereas the Pfizer vaccine produces a barely extra highly effective antibody response (antibodies are proteins that connect to the virus to tag it for destruction).

Which means that the Pfizer vaccine might be higher at defending you towards getting contaminated, whereas the AstraZeneca ‘might present longer-term safety towards hospitalisation and dying’, says Eleanor Riley, a professor of immunology and infectious illness on the College of Edinburgh.
She and different consultants have additionally advised that as a result of the vaccines mobilise T-cells, that are much less ‘inclined’ than antibodies to easy virus mutations, the jabs ought to proceed to guard towards extreme an infection.
Actually Professor Shattock agrees that having a combination appears to be the best choice, although the excellent news is that relating to defending you towards ending up in hospital, each the AstraZeneca and Pfizer jabs have up to now proved to be amazingly efficient. Lengthy might that proceed.
Other than getting a booster, what else are you able to do to make sure a merry, Covid-free Christmas? One factor that’s clear, which wasn’t apparent at the beginning of the pandemic, is that that is virtually solely an airborne illness, so washing your palms or surfaces isn’t going to make loads of distinction.
What we now know is that you simply’re most probably to get contaminated in a confined, poorly ventilated area, surrounded by numerous folks, none of whom are sporting masks, and plenty of of whom are speaking animatedly.
This will imply chopping again on socialising within the run-up to Christmas, notably with people who find themselves not vaccinated.
I lately needed to inform a buddy, who has chosen to not get vaccinated, that he’s now not welcome to a small social gathering I’ve organised subsequent week.
As I defined, that’s as a result of current research counsel an unvaccinated particular person is as much as 20 instances extra more likely to infect you than somebody who’s vaccinated — and none of the remainder of the individuals who have been invited to my celebration needs to threat getting contaminated and passing it on to extra weak, aged family members. It was a tough dialog.
As for sporting masks, a current evaluation of the analysis by scientists on the College of Oxford concluded that sporting a easy masks will halve the variety of viral particles you breathe out, which implies you’re considerably much less more likely to infect others (a visor, nevertheless, has virtually no impact).
What this implies in actual phrases was highlighted by a examine by the Facilities for Illness Management and Prevention within the U.S., which in contrast colleges the place masks are obligatory with these the place they’re not.
Researchers discovered mask-wearing colleges had been three and a half instances much less more likely to have Covid-19 outbreaks.
The underside line: this new variant reveals that the Covid-19 virus is just not completed with us but, and few of us may face one other lockdown.
So watch out.
Not less than a dozen completely different species of human have walked the Earth, and now there’s simply us, homo sapiens.
Arguably, it was the invention of language and the power to make and use instruments that made us prime canine. If it was the latter, it’s simply as properly I wasn’t an early human, as a result of I’m horrible at DIY (take the double glazing I put in, which fell out). But when I labored on my DIY abilities, would possibly that additionally enhance my language abilities?
That was the stunning conclusion of a Swedish examine, which confirmed these two talents depend on neural pathways in the identical space of the mind, and reinforce one another.
Researchers discovered that getting folks to do duties with a pair of pliers improved their ends in language assessments, and vice versa. This additionally reveals how entwined these two abilities actually are.
Fasting is nice in your pets, too!
I’m a giant fan of a kind of prolonged, in a single day fasting, referred to as time-restricted consuming — the place you attempt to go longer with out consuming by extending your regular in a single day quick.
The best approach to do that is to cease consuming just a few hours earlier than mattress, after which delay your breakfast for an hour or so.
There’s proof that going with out meals, in a single day, for 12 hours or extra results in modest weight reduction and enhancements in blood stress, blood sugar and blood fats ranges.
And what’s good for people might also be good for our pets. Our household canine, a King Charles Spaniel referred to as Tari, is fed as soon as a day. However I need to confess I additionally give her scraps from our night meal.
Maybe I shouldn’t. A current examine by the College of Washington within the U.S. primarily based on the consuming habits of greater than 24,000 canine discovered that feeding pets simply as soon as a day could also be key to maintaining them more healthy as they age.
Not solely did the canine given meals as soon as day by day present fewer indicators of dementia, in addition they had decrease charges of ‘gastrointestinal, dental, orthopaedic, kidney/urinary, and liver/ pancreas problems’.
In different phrases, canine that fasted for a giant chunk of the day had been having fun with a more healthy previous age. They had been, presumably, additionally costing considerably much less in vet payments.
This follows one other examine, revealed final 12 months by the College of Guelph, in Canada, which discovered that feeding cats one meal a day makes them leaner and more healthy. Within the examine, eight wholesome cats had one massive meal a day, or 4 small ones (in each circumstances with the identical whole quantity of meals).
After three weeks, they swapped to the opposite consuming sample. Analysis confirmed that when the cats had been fed as soon as a day they had been much less hungry and demanding; in addition they burned extra fats and placed on extra lean muscle. That is essential as a result of cats, like people, are likely to lose muscle mass with age.
So although it could appear harsh, a time-restricted consuming plan could also be simply what your pet wants.
