Dr. Siegel on potential COVID vaccine effectiveness: Unlike annual flu, the virus is not a ‘moving target’


Fox News medical contributor Drs. Mark Siegel said Monday that the common flu, unlike coronoviruses, is a “moving target” that often changes from year to year, while COVID-19 is more stable.

Seifel reacted to “Bill Hemmer Reports” comments from Pfizer CEO Albert Borla, who said there was a “good chance” he would know by the end of October if the company’s potential vaccine would be effective.

Borla said in a recent interview, “In our best case we have a fairly good chance – over 60% – but we’ll find out if the product works by the end of October.” “That doesn’t mean it works, it means we’ll know if it works.”

In that regard, Siegel said Borla told the Food and Drug Administration that 44,000 people would be part of a vaccine test – meaning 22,000 received the vaccine and 22,000 did not.

He told Hemmer that in the first parts of the clinical trial, the vaccine looked promising and that it produced a “strong immune response in patients” – but critics have said that it could only be 50 percent effective if approved. is.

“Let me tell you something. With the flu, we have a virus that is changing all the time. But with SARS-COVID-2, it seems to be a very stable one,” he said.

“If we are not shooting at a target here, there is a possibility that this vaccine is far more effective.”

He described how the US stamped polio through vaccines developed during the 20th century, as well as globally smallpox – two viruses that were more irreversible than not.

“If we get a really effective vaccine, we can definitely stem the tide of COVID,” Seagal said. “I like the number of vaccines I take and I like what I hear. I think it’s a very promising situation.”
