Around 90 percent of coronavirus patients in intensive care units have not had a booster jab, prime minister Boris Johnson said on Wednesday (December 29) - defending his decision not to tighten virus curbs in England.
Speaking at a vaccination centre, Johnson urged people to get "vital" booster jabs, saying "the overwhelming majority" of those currently going into intensive care in our hospitals have not had the booster jab.
"I've talked to doctors who say the numbers are running up to 90 percent of people in intensive care who are not boosted," the prime minister added in Milton Keynes in Hertfordshire.
Those who have not been vaccinated are "eight times more likely to get into hospital," he warned.
The UK has been hit by a huge surge of the new Omicron variant, with England and Wales reporting record case numbers on Tuesday. The UK has been one of Europe's worst hit with a death toll of 148,021.
A fourth dose of Covid-19 vaccine is not needed at present, as latest data shows first booster provides high levels of protection against Omicron variant among older adults, says the Joint Committee on Vaccination and Immunisation (JCVI).
After analysing latest data from the UK Health Security Agency (UKHSA), JCVI said: "There is no immediate need to introduce a second booster dose, or fourth jab,
to the most vulnerable".
Data from UKSHA revealed that single booster dose provides around 90 per cent protection against hospitalisation to those aged 65 and over, even after three months of jab.
However, protection against mild symptomatic infection is short-lived and drops to around 30 per cent by about three months.
The study, which looked at booster doses in those aged over 65, showed that with two vaccine doses, protection against the infection drops to around 70 per cent after three months and to 50 per cent after six months.
The NHS Covid-19 vaccination programme has administered more than 40 million second doses following a bumper week that saw over 200,000 people coming forward
for their second jab.
Last week, more than 65,000 people aged 18 and over also stepped up to get their first dose of the Covid-19 jab.
The NHS continued to encourage people to come forward for their first, second or third doses.
Recent data from the UK Health Security Agency (UKHSA) showed that two doses of the vaccine are not enough to avoid the Omicron infection, but a booster significantly
increases protection against the variant.
Since the start of vaccination programme, NHS England has administered more than 113 million jabs in total. However, more than 1.1 million people aged 18 and over have still not come forward for their second dose.
Prime minister Boris Johnson received his Covid-19 booster shot on Thursday (December 2) and urged others to follow suit to help the country fend off the Omicron variant of coronavirus.
Wearing a mask, Johnson briefly chatted to staff and others queuing for their shots at the vaccination centre in central London, asking them if they were there to receive a booster dose and thanking them for attending.
Johnson, who said it could "have gone either way" when he was treated in hospital for Covid last year, was later filmed rolling up his shirt sleeve and receiving his shot.
"Fantastic. Thank you so much," he said to the nurse, before receiving a badge that said "I've boosted my immunity".
Health and social care workers in England, including those working in community pharmacy, will no longer have to have a Covid jab as a condition of employment from later this month, the government said on Tuesday (March 1).
The government had announced on January 31 that it intended to revoke the regulations that made vaccination compulsory, subject to the results of a public consultation.
The decision was taken because the Omicron strain of the virus was less severe than the Delta variant, and due to high rates of vaccination of people in the UK.
Health secretary Sajid Javid told parliament in a written statement that more than 90,000 health and social care workers and members of the public responded to the consultation.
The minimum Covid-19 self-isolation period in England will be cut to five days from seven if someone tests negative twice, health secretary Sajid Javid said on Thursday (January 13) - a move that could reduce staffing disruption in businesses and infrastructure.
The rapid spread of the Omicron variant has fuelled a spike in Covid-19 cases to record highs in Britain, and the surge has cause major disruption to the staffing of hospitals, schools and transport as staff have to self-isolate.
"We've made the decision to reduce the minimum self-isolation period to five full days in England," Javid told parliament.
"From Monday, people can test twice before they go, leaving isolation at the start of day six."
The government had previously reduced isolation period to seven days from 10 days to people in England who get a negative result on a rapid lateral flow test two days in a row.
A news report suggests the Department of Health and Social Care is aiming to be ready to start charging for Covid-19 tests which are currently free at the end of June.
Britain has been increasingly dependent on rapid testing to try to tackle the more-transmissible Omicron variant, which has spread rapidly through the population but is less severe.
The government has previously said it will end the universal free provision of easy-to-use lateral flow devices (LFDs) at a "later stage", with individuals and businesses bearing the cost.
The Department of Health has declined to say what the tests cost, citing commercial contracts. One source has told the Reuters news agency they can run to £30 for a pack of seven.
Free pick up from pharmacies
The tests have been made freely available to order online or pick up from local pharmacies since April. The UK Health Security Agency said that between December 30 and January 5 more than 8 million LFDs were conducted, the highest weekly figure on record.
The NHS Confederation has urged the government to reconsider its 'living with Covid' plan and introduce mitigating actions that will help avoid further
critical incidents being declared at the NHS front-line.
The organisation said the high rates of Covid is having a major impact on the delivery of health services and slowing down efforts to reduce large waiting lists,
noting that the country has been in the grip of another spike in Covid cases resulting from the Omicron BA.2 variant.
With more than 20,000 patients now in hospital with Covid (or who have Covid but are in hospital for other reasons) and high staff absences, NHS is facing huge
operational challenges, harming efforts to reduce waiting times in other areas, it said.
It is not sustainable to give Covid-19 booster shots every three to six in the long term, Britain's chief scientific adviser said on Tuesday (January 4), even though the booster rollout is needed in the short term to combat the Omicron variant.
"It would be a situation that isn't tenable to say everyone's going to need to be having another vaccine every three or six months.
"That's not the long-term view of where this goes to," Patrick Vallance said at a news conference, adding that annual booster shots against Covid-19 might be necessary, similar to flu shots.
