Pfizer Looks to Authorize Booster Vaccine Dose as Antibodies ‘wane,’ Delta Variant Spreads

Pfizer says that booster shots are particularly important in older age groups



Pfizer Vaccine

Pfizer Inc’s top scientist said on Thursday the drugmaker will be asking U.S. regulators to authorize a booster dose of its COVID-19 vaccine within the next month. “The Pfizer vaccine is highly active against the Delta variant,” said Pfizer Chief Scientific Officer Mikael Dolsten.

However, after six months “there likely is the risk of reinfection as antibodies, as predicted, wane” he said. Dolsten said the recently reported decrease of vaccine efficacy in Israel was mostly due to infections in people who had been vaccinated in January or February.

The country’s health ministry said vaccine effectiveness in preventing both infection and symptomatic disease fell to 64% in June, reported Reuters. Dolsten said Pfizer did not release the full set of Israeli data on Thursday but will publish it soon.

“It’s a small data set, but I think the trend is accurate: six months out, given that Delta is the most contagious variant we have seen, it can cause infections and mild disease,” said Dolsten. He also added Pfizer’s data from the United States also shows a decline in the vaccine’s effectiveness to the mid-80s after six months.

Dolsten did stress that data from Israel and Britain still suggest that even with waning antibody levels, the vaccine remains around 95% effective against “severe disease.”

Reuters reports:

The vaccine, developed with German partner BioNTech SE, showed 95% efficacy in preventing symptomatic COVID-19 in a clinical trial the companies ran last year.

Dolsten said that early data from the company’s own studies shows that a third booster dose generates antibody levels that are five to 10-fold higher than after the second dose, suggesting that a third dose will offer promising protection.

He said multiple countries in Europe and elsewhere have already approached Pfizer to discuss booster doses, and that some may begin administering them before a potential U.S. authorization.

Dolsten said he believes that booster shots are particularly important in older age groups.

Pfizer has previously said individuals will likely need a booster dose. “But some scientists have questioned when, or whether, they will be needed” writes Reuters. Pfizer and BioNTech are also designing a new version to target the Delta variant, but Dolsten said the companies do not believe that the current version will need to be replaced in order to combat the variant.

    Gee, it’s almost like the Grope’s Administration is working with the vaccine companies to continually require more vaccinations and more money.

Kamala Harris

On Tuesday, the White House announced that Vice President Kamala Harris has tested positive for COVID-19 and is not currently showing symptoms.

“Today, Vice President Harris tested positive for COVID-19 on rapid and PCR tests,” said Kirsten Allen, press secretary to the vice president. “She has exhibited no symptoms, will isolate and continue to work from the Vice President’s residence. She has not been a close contact to the President or First Lady due to their respective recent travel schedules. She will follow CDC guidelines and the advice of her physicians. The Vice President will return to the White House when she tests negative.”

Harris wrote on Twitter that she was going to continue to isolate and is showing no symptoms.

“Today I tested positive for COVID-19. I have no symptoms, and I will continue to isolate and follow CDC guidelines. I’m grateful to be both vaccinated and boosted,” Harris tweeted.

Harris last reportedly saw President Biden at the Easter Egg Roll on April 18 before leaving for California, which she returned from on April 25.

The vice president has been vaccinated against COVID-19 and has received two booster shots, receiving the second booster on April 1.

“Yesterday I received my second COVID-19 booster shot,” Harris tweeted on April 2. “We know that getting vaccinated is the best form of protection from this virus and boosters are critical in providing an additional level of protection. If you haven’t received your first booster—do it today.”

At Least 3 US Airlines Will Restore Flight Privileges To Some Mask Violators



At least three major U.S. airlines – Delta Air Lines, United Airlines and American Airlines – have now said they will allow some passengers who were banned from their planes over mask violations to have their flight privileges restored – determined on a case-by-case basis.

On Wednesday, Delta released a statement saying, “At Delta, nothing is more important than the safety and security of our customers and our people. With masks now optional, Delta will restore flight privileges for customers on the mask non-compliance no-fly list only after each case is reviewed and each customer demonstrates an understanding of their expected behavior when flying with us.”

“Any further disregard for the policies that keep us all safe will result in placement on Delta’s permanent no-fly list. Customers who demonstrated egregious behavior and are already on the permanent no-fly list remain barred from flying with Delta,” the statement added.

United Airlines similarly announced it will allow passengers it banned for not following mask rules to be allowed to fly again.

“On a case-by-case basis, we will allow some customers who were previously banned for failing to comply with mask-related rules to fly United again — after ensuring their commitment to follow all crewmember instructions on board,” United Airlines said in a statement.

American Airlines will also allow passengers banned for violating mask rules “to resume travel at some point in time,” according to the company’s chief government affairs officer, Nate Gatten.

“In cases where an incident may have started with face mask noncompliance and escalated into anything involving something more serious, or certainly an assault on one of our key members or customers, those passengers are going to remain on our permanent internal refuse list and will never be allowed to travel with us again,” Gatten said.
