T-cells in Pfizer Covid jab recipients stay robust against severe illness

Research in South Africa raises hopes that similar responses may be present with other vaccines

South African researchers examining how the body’s immune system responds to the Omicron variant have identified that T-cells in people who have had the Pfizer vaccine continue to be robust in potentially protecting against severe illness despite Omicron’s ability to evade other defences.

The research raises hopes that similar responses may be present with other vaccines and within unvaccinated individuals who have been infected with coronavirus.

Why a UK Omicron wave is dangerous – even if we see mostly mild cases

Analysis: If the spread continues at this rate, a small proportion of Covid hospitalisations is a serious matter

With the booster programme at full tilt across the UK, immunity against Covid is rising – so it is perhaps not surprising that the concern shown by experts over the steep rise in Omicron infections has left some bemused.

For while the new variant is believed to dodge Covid vaccines to some degree, it is thought the jabs still offer good protection against severe disease – particularly after a booster. And greater levels of immunity mean a lower ratio of hospitalisations to cases – something we have seen before in the UK, where about 22% of cases in those aged 65 and older ended up in hospital in early 2021, when Alpha was dominant but few had received a vaccine, compared with about 6% after the vaccine rollout was well under way.

Bolsonaro threatens to identify officials who approved Covid jabs for children

Brazilian president plans to reveal identities despite health officers receiving death threats

The Brazilian president, Jair Bolsonaro, has asked for the names of health officials who approved Covid vaccines for children, saying he planned to make their identities public despite previous death threats.

In late October, Brazil’s health regulator, Anvisa, released a statement saying five of its directors had received death threats over the possible approval of vaccinations for children of five-11. The agency granted such approval for the Pfizer shot on Thursday.

Covid news live: France restricts UK tourists over Omicron; Portugal to lengthen border controls

British tourists banned from entering France from Saturday; border controls in Portugal extended beyond 9 January to limit Omicron spread

New Zealand has detected its first case of the Omicron Covid-19 variant in a Christchurch managed isolation facility.

On Thursday afternoon, the director general of health Dr Ashley Bloomfield said:

This is a person who is in managed isolation in Christchurch. The person arrived in New Zealand on a flight from Germany via Dubai that landed in Auckland...the people on that flight were transferred to Christchurch on a chartered domestic flight trip with all our usual protocols.

We fully expected we will find a case of Omicron and in fact, we are treating every border related case as if it were Omicron until proven otherwise. We have good protocols in place that are designed to stop the virus getting across the border.”

Omicron R number estimated to be between 3 and 5, says UK health adviser – video

Dr Susan Hopkins, the chief medical adviser at the UK Health Security Agency, told a select committee on Thursday that for Omicron the R value was between 3 and 5 in the UK and that the variant was spreading rapidly – doubling in size every two days.

Hopkins said data on the severity of Omicron would not be known for another fortnight. At least 250 patients would need to be admitted to hospital before there could be a statistical analysis of the disease, she said

Housebound elderly people are having to wait weeks to get their booster vaccine, despite being a key priority group for top-up jabs, raising fears about them being left at risk.

Charities have warned that older people are being “overlooked” in the NHS’s rush to deliver the 1m boosters a day that Boris Johnson has ordered to reduce the threat posed by the Omicron variant.

GSK/Sanofi Covid booster delayed by lack of uninfected people to test it on

Early trials show jab effective in people of all ages who have already received doses of any vaccine

Efforts by the British and French drugmakers GSK and Sanofi Pasteur to produce a Covid-19 vaccine have suffered a further setback, with final clinical data on the jab and a potential launch delayed until next year as they struggle to find enough uninfected people to test it on.

The two vaccine specialists announced positive preliminary results from a trial that showed the vaccine raised antibody levels against Covid by nine to 43 times when given as a single booster shot in people who had already received doses of AstraZeneca, Johnson & Johnson, Moderna or Pfizer/BioNTech vaccines, for all age groups.

Covid passports could increase vaccine uptake, study suggests

Certification encouraged vaccination in countries with low coverage, especially among young people

Coronavirus passports could lead to increased uptake of vaccines, especially among young people, a study suggests.

Research by the University of Oxford found Covid-19 certification led to increased jab uptake 20 days before and 40 days after introduction in countries with lower-than-average vaccination coverage. Increase in vaccine uptake was most pronounced in people under 30. The modelling analysis was published in The Lancet Public Health.

Time to chat about next year’s election, and the battle the treasurer is facing from an independent in his home seat.

Michael Rowland:

You are now facing, as we know, Monique Ryan in the seat of Kooyong. She’s a Royal Children’s hospital doctor. You’ve labelled people like she, an independent, as a front for Labor and the Greens. What evidence do you have for that?

Well, at the last election, I had an independent who said they were gonna vote for Labor. That’s a pretty clear indication. We’ve also seen plenty of cases where they’ve just mirrored the policies of our political opponents.

But what evidence do we have at this time?

This is a rinse-and-repeat, Michael. What we’ve seen, we’ve seen obviously a lot of funding going into these independents around the rest of the country, and it’s a democracy, so people can put their hand up.

Just on Omicron, you might have caught up with the news just in the last hour or so, Boris Johnson, the UK prime minister, made an address to the nation there. He’s declared a tidal wave of Omicron case is about to hit the UK.

He’s declared it a public health emergency, and has declared that all British adults over the age of 16 can get a booster shot by the end of the year. Taking that into account, are we being a bit too sanguine about Omicron here in Australia?

We saw the medical advice, and that saw a pause for two weeks of the reopening of the border to international students and to skilled workers.

That was a precautionary measure. But we will continue to listen and follow the health advice, and it has served us well to date.

Johnson addresses the nation as Covid alert level raised due to Omicron – video

Boris Johnson has announced that the government is launching an emergency booster campaign to avoid a severe rise in hospitalisations and deaths from a 'tidal wave' of Omicron. The prime minister said infections of the Covid-19 variant, first identified in South Africa, were doubling every two to three days, and that two doses of vaccine 'are simply not enough to give the level of protection we all need'.

Speaking in a televised address on Sunday night, Johnson announced the booster programme would be offered to everyone over the age of 18 in the UK, with extra capacity provided by 'additional vaccine sites and mobile units' and '42 military planning teams across every health region'
