Illinois hospital to resume Covid-19 vaccinations after four workers have adverse reactions

From CNN's Hollie Silverman and Travis Nichols

A hospital in a suburb of Chicago will resume a Covid-19 vaccination program for frontline personnel on Sunday, a day after it paused immunizations when four workers experienced reactions, according to a press release from Advocate Aurora Health.

CNN previously reported that four workers at Advocate Condell Medical Center, in Libertyville, Illinois, experienced tingling and elevated heart-rate symptoms shortly after receiving the vaccine.

The hospital decided to resume vaccinations after a "review confirmed the quality of the vaccine batch" and the hospital's protocols for distribution, the release said.

The release said the post-vaccination evaluation period will now be extended to 30 minutes for all individuals following the adverse reactions, which exceeds recommendations made by the US Centers for Disease Control and Prevention (CDC).

Advocate Aurora Health reported the adverse reactions to the CDC, according to the release.

What happened: One of the health care workers who had an adverse reaction to the vaccine suffered what "appears to be a severe allergic reaction," the release said. 

"That individual is doing well and was discharged today after being monitored overnight. The other three individuals were at home yesterday and doing well after experiencing reactions that can happen with vaccination," the release said.

Londoners piled on to trains and motorways on Saturday night as they rushed to leave the capital ahead of new restrictions announced by UK Prime Minister Boris Johnson.

Johnson announced that London and large parts of south-eastern England will enter Tier 4 Covid-19 restrictions on Sunday.

Tier 4 is the highest possible level of restrictions in England, effectively renewing the lockdown seen in Spring.

By 7 p.m. on Saturday evening, there were no free seats on trains leaving London from several stations in the capital, PA News Agency reports. Passengers complained about not being able to socially distance themselves within the train carriages.

The scenes were condemned by politicians and public health experts. London Mayor Sadiq Khan called the introduction of the restrictions "devastating" in an interview with the BBC, adding that scenes at London train stations "was a direct consequence of the chaotic way the announcement was made, and the late stage it was made.

I understand why people want to return to see their mums, dads, elderly relations, but I think it’s wrong," he said.

Speaking directly to Londoners who left London, he said that while they may have not broken the rules, they may have taken the virus out of London and potentially put “your mum, dad, elderly relations" at risk.

Dr. Chaand Nagpaul, British Medical Association (BMA) council chair, said that such scenes would not have been seen "in east Asian countries that have managed pandemics well in the past," adding that the government should have made sure there were crowd control measures.

“Whilst Christmas is obviously going to be ruined for many, the worst thing we could be doing is infecting our loved ones," he told Sky News.

UK Health Secretary Matt Hancock defended the government's actions on Sky, saying they had no choice to act after being presented with new scientific evidence that a new strain of the virus was spreading more quickly than others in the UK.
"It was our duty to act,” he said. "We acted very quickly and decisively with the announcements the Prime Minister set out yesterday."

New strain: England's chief medical officer, Professor Chris Whitty, warned Saturday that a newly identified variant of Covid-19 "can spread more quickly" than previous strains of the virus.

"This is now spreading very fast," Johnson warned. "It is with a very heavy heart that I say we cannot continue with Christmas as planned."

As with other new variants or strains of Covid-19, this one carries a genetic fingerprint that makes it easy to track, and it happens to be one that is now common. That does not mean the mutation has made it spread more easily, nor does it not necessarily mean this variation is more dangerous.

Two more Alaska health care workers suffer adverse reactions to Covid-19 vaccine

From CNN's Hollie Silverman

Two health care workers at Providence Health Alaska suffered adverse reactions to a Covid-19 vaccine late last week, Mikal Canfield, a spokesman for Providence Alaska, told CNN on Saturday night.

Five adverse reactions to the vaccine have now been reported in Alaska. Last week, three health care workers in the state had allergic reactions after receiving doses of the Pfizer-BioNTech Covid-19 vaccine, CNN previously reported.

Providence Alaska is not releasing the location where the two health care workers are employed, but the network has locations in Anchorage, Valdez, Seward and Kodiak, according to Canfield.

The health care workers who received the vaccine are "frontline caregivers involved directly with patient care," Canfield said.

They suffered mild and non-life-threatening reactions but have not consented to additional information on their conditions being released, Canfield said. 

Canfield told CNN Providence Alaska has reported the adverse reactions to the state health department and the Centers for Disease Control and Prevention's Vaccine Adverse Event Reporting System (VAERS).

CNN also reported Saturday that an Illinois hospital paused its Covid-19 vaccinations after four workers experienced reactions. 

CNN has reached out to the Alaska Department of Health and Social Services, as well as Pfizer, for comment.

Japan recorded 2,985 new coronavirus infections and 45 related deaths on Saturday, the Japanese health ministry said on Sunday.

The country's total Covid-19 caseload now stands at 196,592, with 2,886 deaths.

Hospitals across Japan are currently caring for 26,169 Covid-19 parents, among whom 598 are under intensive care. 

Over the past weeks, a resurgent winter wave has seen daily case numbers climb to their highest levels since the beginning of the pandemic.

The surge in cases is being fueled by a worsening situation in capital Tokyo, where 739 new cases were recorded Saturday.

Another hard-hit prefecture, Osaka, recorded 311 new patients Saturday.

Some context: Japan, along with its neighbor South Korea, is seeing a rise in Covid-19 cases and hospitalizations as cold winter temperatures set in. Winter was always expected to bring a spike in cases, as cold weather sends people indoors to poorly ventilated spaces -- conditions likely to make coronavirus spread more easily.

In Japan, cases have been rising steadily since the start of last month. On November 1, just over 600 cases were reported. Twenty days later there were more than 2,500 daily infections.

Residents of Australia’s most populous city, Sydney, are no longer able to travel interstate without quarantining as a mystery Covid-19 cluster spreads in the city.

All Australian states and territories will require travellers from Sydney to undergo a 14-day quarantine on arrival, according to state governments.

On Saturday, 30 new locally transmitted cases of Covid-19 were detected in Sydney, all located in the Northern Beaches municipality.

The cluster has now grown to 68 cases, with its source still unknown.

Residents of the Northern Beaches have been told to stay in their homes until 11:59pm on Wednesday.

“It’s been done largely instinctively up there on the Northern Beaches,” Prime Minister Scott Morrison said on Sunday, “I know that they’re looking to see things change in the not too distance future and they know that compliance can only help with getting that outcome.”

US Congress on brink of deal on $900 billion relief package after resolving key dispute

From CNN's Manu Raju and Clare Foran

A deal on a long-awaited rescue package to deliver much-needed aid to struggling Americans suddenly was within reach after a major breakthrough Saturday night over a key sticking point: the role of the Federal Reserve to intervene in the US economy.

After days of tense negotiations over a provision pushed by Sen. Pat Toomey to pare back the role of the central bank's emergency lending authority, Senate Minority Leader Chuck Schumer and the Pennsylvania Republican reached a deal in principle over the provision, aides said. Now, the two sides will draft the legislative language to ensure it reflects the outlines of the deal.

More than 16 million people in England will be subject to stricter coronavirus restrictions

More than 16 million people in England -- or 31% of the British population -- will spend their Christmas holiday under stricter coronavirus regulations, which are set to go into effect on Sunday, according to the UK government's Covid-19 task force.

The Tier 4 measures will be imposed on London and southeast England. They amount to a lockdown and will severely curtail movement over the Christmas holiday.

Prime Minister Boris Johnson announced the new restrictions on Saturday. He said the Tier 4 lockdown was needed in affected areas after a newly identified strain of Covid-19 has proved to spread more quickly than previous strains of the virus. 

"The spread is being driven by the new variant of the virus," Johnson said in a hastily called press conference. "It appears to spread more easily and may be up to 70% more transmissable than the earlier strain."

Johnson outlined that in Tier 4 areas under the toughest restrictions, there will be no possibility for household mixing over Christmas. In areas under lower alert levels in England, Scotland and Wales, mixing will now be permitted only on Christmas Day.

According to the country's Covid-19 task force, 19.7 million people, or 37% of the UK population, will live under Tier 3 guidelines, 16.1 million or 30% will live under Tier 2 and 856,000 or 2% will live under Tier 1 restrictions.

The Netherlands will ban all passenger flights from the United Kingdom starting at 6am local time Sunday, according to a press release from the government.

The Dutch government said it is doing so in order to minimize “as much as possible” the risk of a new coronavirus strain detected in the UK spreading in the Netherlands. The flight ban will remain in place until the new year, according to the release. 

The Dutch government said the same variant of the virus had been detected in the Netherlands in a sample from a case from early December, and that it is conducting further investigations to determine if there are any other related cases.

Earlier on Saturday, UK Prime Minister Boris Johnson imposed stringent new lockdown measures on the capital and surrounding areas to slow the spread of the virus. The Tier 4 lockdown has forced Christmas holiday plans for more than 16 million people in the UK to be severely curtailed.
