During an appearance on ‘Fox & Friends Weekend,’ Fox News senior medical analyst Dr. Marc Siegel discussed the surge in estimated cases of Lyme disease in the United States and how Pfizer is developing a new vaccine for the illness. Siegel said Pfizer’s Lyme disease vaccine should be available “in a few months.” “I have a feeling with this spotlight they may fast-track it. It’s a completely safe vaccine based on older technology. It’s not something that we don’t know about,” Siegel explained. Siegel said the vaccine is “very promising” and it’s “going to be useful.” “Last time we had a Lyme vaccine, nobody took it. This vaccine is safe [and] effective. I think we’re going to get a lot of use out of it,” he added.

Pfizer said the vaccine missed the trial’s statistical goal because not enough people in the study contracted Lyme disease to be confident in the results. Still, the company said the shot reduced the rate of infection by more than 70% in people who received the vaccine versus placebo, efficacy the company thinks is strong enough to take to regulators. “The efficacy shown in the VALOR study of more than 70% is highly encouraging and creates confidence in the vaccine’s potential to protect against this disease that can be debilitating,” Pfizer Chief Vaccines Officer Annaliesa Anderson said in a statement. A vaccine for Lyme disease isn’t expected to become a best-seller for Pfizer, with the company’s partner Valneva estimating peak annual sales of $1 billion. Pfizer expects overall revenue of around $60 billion this year, with its Covid-19 vaccine representing more than $5 billion of that forecast. But Pfizer had billed the Lyme vaccine results as one of its major catalysts this year, and it represented a chance to introduce the only human vaccine for Lyme disease. “I don’t want any more safe and effective vaccines. I want them to stop engineering ticks and viruses as bio weapons,” former Congresswoman Marjorie Taylor Greene commented. I don’t want any more safe and effective vaccines.

Kennedy Jr. announced a major federal push to fight Lyme disease and other tick-borne illnesses. “One of the real tragedies now is that American’s can’t go into the woods anymore safely— and going to the woods to hike, to fish, to hunt, to photograph, or just a walk in the woods is part of the seminal experience of being an American, and particularly an American child— and it’s a science fiction nightmare that we now live in,” RFK Jr. said.

We aim to slow the spread of Lyme disease,” he continued.

Lyme disease now affects an estimated 476,000 Americans each year and remains one of the most common vector-borne diseases in the United States,” RFK Jr. said last month. “I recently wrote to the House Energy & Commerce Committee urging support for reauthorization of the Kay Hagan Tick Act to strengthen research, surveillance, early detection, treatment, and public awareness efforts related to tick-borne disease,” he added.

It was said to reduce new infections in vaccinated adults by nearly 80 percent, according to an editorial review published by the Cambridge University Press. The disease is spread to hundreds of thousands of people in the U.S. each year by blacklegged ticks. Infected ticks must be attached for more than 24 hours to transmit infection; prompt tick removal can prevent transmission, according to the Center for Disease Control and Prevention. It’s typically contracted during outdoors activities and ultimately treated with a 10- to 14-day course of oral antibiotics, according to the University of Pennsylvania. Watch more below:
