Will the omicron Covid variant wreck Christmas?

Judging by my mailbox, there is only one Covid question on people's minds at the moment – will omicron ruin Christmas?

England’s Covid-susceptible population among lowest in Europe

The number of people in England who are susceptible to Covid is one of the lowest in Europe, analysis has shown.

The AstraZeneca vaccine's unlucky few

“I would just like them to hold their hand up and say, ‘we’re very much aware that this has happened and we’re going to do something about it’. And I’d like them to do that without taking it away in the next breath. “In no other circumstances where so many people have lost their lives would that happen.

What happens to your body and your health when you lose your temper

It’s long been thought of as a toxic emotion and now a new study suggests that an explosion of anger can, in some cases, trigger a stroke. The global study, co-led by National University of Ireland (NUI) Galway, found that one in 11 stroke survivors had experienced a period of anger or upset in the one hour leading up to it. The large-scale researc...

Covid data shows omicron could more than double reinfection risk - but don't panic yet

Alarming new data from South Africa suggests that the omicron variant could more than double the risk of being reinfected with coronavirus, leading predictably to calls for tough restrictions to be brought in to stop the spread in Britain. Researchers from Witwatersand and Stellenbosch universities discovered that reinfections increased substantial...

'Worrying' number of children and pregnant women in hospital as omicron surges in South Africa

The new omicron variant may be hospitalising more children and pregnant women than in previous waves, a leading doctor at the largest hospital in Africa told The Telegraph.

Feed your dog just once a day to prevent future health problems, says study

Feeding your dog once a day could reduce the risk of them suffering age-related health issues, a new study claims. Information from more than 20,000 pet owners was gathered by researchers at the University of Washington, in Seattle, via questionnaires to gauge their pets’ cognitive ability and how feeding routines impacted on canine health. Owners ...

Scrapping Valneva Covid vaccine ‘not terribly clever’, warns JCVI scientist

The Government’s decision to scrap the French-made Valneva vaccine has been branded as “not terribly clever” by a member of the Joint Committee on Vaccination and Immunisation as the jab likely offers good protection against mutant Covid-19 variants, including omicron. Boris Johnson visited Valneva’s Scottish manufacturing site in Livingston in Jan...

Calm down about omicron... UK’s immunity is different to South Africa’s, says expert

Britain should “calm down” about omicron because new research suggests that UK immunity will be very different to South Africa and vaccines are holding up well, a leading immunologist has said. Danny Altmann, the professor of immunology at Imperial College London, said he had been initially terrified after seeing the amount of worrying mutations th...

Help! Have you got PCSD (Pre-Christmas Stress Disorder)?

Do you remember how it used to be at this time of year, before Covid robbed us of our ability to trust that essential things like Christmas would just happen as planned?

Will we end up having booster jabs forever? Here’s everything you need to know

A year after Britain became the first country in the world to approve a coronavirus vaccine, the arrival of the omicron variant has brought with it a new focus: the booster rollout.

Omicron can re-infect patients who have had coronavirus before, South African scientist says

A previous bout of Covid-19 does not appear to protect against re-infection with the new omicron variant, according to a leading South African scientist. Speaking at a World Health Organization (WHO) briefing on Thursday, Professor Anne von Gottberg, a microbiologist at South Africa's National Institute for Communicable Diseases, said: "Previous in...

Booster vaccines create T-cells that protect against all Covid variants – including omicron

Booster jabs produce long-lasting T-cells that are likely to work against all current and future coronavirus variants, including omicron, according to a new study. Data from the government-funded Covboost trial has been published in The Lancet and reveals how effective different vaccines are as boosters when it comes to enhancing levels of T-cells ...
