The results are based on blood samples taken from adults one week after they received the updated booster. The FDA also authorized Moderna's updated booster based on similarly limited data. The FDA authorized the updated shots based on studies in mice — plus human trial results from a similar booster that targets the original omicron strain, called BA.1. At the time, Dr. Peter Marks, the FDA's top vaccine regulator, said the agency hoped the updated vaccines will provide stronger protection against symptomatic disease than the older vaccines. Moderna didn't immediately respond to a request for comment about when it will release new data on its updated booster.
Oct 13 (Reuters) - Pfizer (PFE.N) and its German partner BioNTech said their COVID-19 vaccine booster, adapted for the BA.4 and the BA.5 subvariants of Omicron, generated a strong immune response and was well-tolerated in testing on humans. With the results, which the companies described as consistent with preclinical data, the partners are following up with human trial data that had previously been missing from their successful filings for regulatory approval.

Healthcare regulators for the European Union and the United States had already approved the upgraded shot last month, even though trial data from testing on humans had at the time not been available. “While we expect more mature immune response data from the clinical trial of our Omicron BA.4/BA.5-adapted bivalent vaccine in the coming weeks, we are pleased to see encouraging responses just one week after vaccination in younger and older adults," said Pfizer Chief Executive Albert Bourla.
Covid Vaccines Could Mirror the Flu Shot Process.

Pfizer and its German partner BioNTech on Thursday said their new omicron boosters substantially increased protective antibodies against the dominant omicron BA.5 subvariant for adults in the first direct human data released to the public on the new shots. The participants who received the first generation vaccine saw a limited increase in antibodies against BA.5, according to the companies. The early data indicate that the safety profile of the new boosters is the same as the original vaccine, the companies said. The first generation shots were developed only against the first strain of the virus. The FDA authorized the omicron shots without direct human data on how they perform against omicron BA.5, which is causing most infections in the U.S. right now.

Oct 12 (Reuters) - U.S. health regulators authorized the use of Omicron-tailored COVID-19 booster shots from Moderna Inc (MRNA.O) and Pfizer Inc (PFE.N) in children as young as 5, a move that will expand the government's fall vaccination campaign. The U.S. Food and Drug Administration on Wednesday green-lighted Moderna's bivalent vaccine for those aged six and above, while Pfizer's updated shot was authorized in children aged five and above. The U.S. Centers for Disease Control and Prevention also backed the FDA's authorization, clearing the way for the shots to be administered in children. Overall, COVID-19 vaccination rates in the United States have stayed low among kids, with nearly 40% of children aged 5-11 vaccinated with one dose of a vaccine so far. Around 11.5 million people received the updated shots over the first five weeks of the rollout last month, which represents just 5.4% of the people aged 12 or older who are eligible to receive them.

Flu cases are already rising in parts of the U.S., according to the Centers for Disease Control and Prevention. The convergence of viruses is hitting health care systems as they're forced to reckon with staffing shortages that worsened during the pandemic. Staffing deficits mean there is little wiggle room to accommodate any additional surges of patients, whether they're sick with Covid, flu or other illness. But as the cold weather sets in and people increasingly gather indoors, Covid cases are expected to rise. The vast majority of Covid cases circulating now are an omicron subvariant, BA.5.

BERLIN, Oct 10 (Reuters) - Swiss drugs regulator Swissmedic said on Monday it had temporarily approved Pfizer's COVID-19 booster shot targeting the original and BA.1 Omicron coronavirus variants. Swissmedic added that the data currently available to it was not yet sufficient to make a decision on Pfizer's bivalent booster vaccine targeting the BA.4 and BA.5 Omicron variants.

Americans have two options for a new omicron-specific Covid booster shot: Pfizer or Moderna. Pfizer's booster is cleared for anyone 12 and older, while Moderna's booster is for people 18 and older. "People ages 18 years and older may get a different product for a booster than they got for their primary series, as long as it is [Pfizer or Moderna,]" the CDC's website reads. "It's OK to mix and match Moderna and Pfizer," Dr. Ralph Gonzales, associate dean for clinical innovation at UC San Francisco, said at a campus town hall earlier this month. I definitely felt a stronger response with the Moderna — having had Pfizer before — but either combinations are fine."
Pfizer asked U.S. regulators Monday to expand the use of its updated Covid-19 booster shot to children ages 5 to 11. Elementary school-aged children already received kid-sized doses of Pfizer’s original vaccine, a third of the dose given to everyone 12 and older — two primary shots plus a booster. Pfizer and its partner BioNTech also announced a new study of the omicron-focused booster in even younger children, those ages 6 months through 4 years, to test different doses. Updated boosters made by both Pfizer and rival Moderna rolled out earlier this month for everyone 12 and older. As of last week, the Centers for Disease Control and Prevention said 4.4 million Americans had gotten an updated booster so far.
(CNN) Younger children could soon be eligible to receive an updated Covid-19 booster shot. Pfizer and BioNTech on Monday said they completed their submission to the US Food and Drug Administration for emergency use authorization of their updated Covid-19 booster for children ages 5 through 11. Moderna on Friday said it had requested FDA authorization for its updated booster for adolescents ages 12 to 17 and for children ages 6 to 11. Like the boosters that became available for older people earlier this month, these bivalent boosters target the original coronavirus strain as well as the Omicron BA.4/BA.5 subvariants. Pfizer's updated booster is currently authorized for use in people 12 and older and Moderna's is authorized for adults age 18 and older.
Canada to remove all Covid travel restrictions from Oct. 1

Cars line up at Canadian side of the border between Canada and the United States, near Seattle, Washington and Vancouver, British Columbia on August 9, 2021. Canada will drop all Covid-19 restrictions for travelers from Oct. 1, including vaccination and masking requirements for flights and trains, the government said on Monday. The move is likely to boost the Canadian travel industry, already booming after months of lull during the pandemic. More than 90% of Canadians over 12 have taken the primary series of a Covid vaccine. Cruise ship passengers and crew would also no longer be subject to vaccine requirements or Covid testing.

The rollout of bivalent booster doses for older age groups has been off to a slow start in the United States compared to the rollout of the first boosters last year, with 4.4 million doses administered so far. read moreEarlier in the month, the U.S. Centers for Disease Control and Prevention said it expects COVID-19 vaccine boosters targeting circulating variants of the virus to be available for children aged 5-11 years by mid-October.

At least 4.4 million people have received an updated Covid booster since the start of the month, according to data released Thursday by the Centers for Disease Control and Prevention. The CDC signed off on updated versions of Pfizer’s and Moderna’s booster shots on Sept. 1, and pharmacies and other vaccination sites began administering the new shots around Labor Day weekend. As of Tuesday, the U.S. had shipped more than 25 million bivalent booster doses to tens of thousands of sites. Some pharmacies reported shortages of Moderna's updated booster earlier this week. Biden administration officials have pointed to the updated boosters, however, as a critical step to pushing the U.S. out of the pandemic.
