The U.S. drugmaker bought rights to a promising antiviral discovered at
“This is a global pandemic. No one country can solve it, and we can’t put borders around any one country,” Frazier said in a phone interview. “If we’re successful, we want to ensure broad, affordable access for whoever needs it, wherever they are.”

“I hope the people who are predicting a faster timeline than we have ever imagined are right, but we are talking about vaccinating the world, not just people in a given developed country,” she said during a discussion Tuesday hosted by the Federal Reserve Bank of Minneapolis and the University of Minnesota.
Merck shares rose 1.2% to $77.28 at 4:23 p.m. in New York. They’ve fallen more than 14% so far this year, outpacing losses seen by the S&P 500 amid broader economic tumult.
The Kenilworth, New Jersey-based company, which has pioneered inoculations to stop diseases from diphtheria to Ebola, has evaluated hundreds of potential Covid-19 vaccines, Frazier said. Below are the highlights of news announced in separate statements:
- Collaboration with
IAVI and funding from the Biomedical Advanced Research and Development Authority, or BARDA, to develop a vaccine using technology behind Merck’s Ebola shot - Acquisition of Themis to gain another vaccine candidate that uses measles virus vector platform discovered by the Pasteur Institute
- Rights to EIDD-2801, an oral antiviral candidate in early clinical development, bought from Ridgeback Biotherapeutics LP and discovered at Emory University
Ebola Inspiration
Merck’s immunization against Ebola -- the only one approved by the Food and Drug Administration -- provided a reference point for a candidate Covid vaccine since it confers protection with a single shot and uses technology that’s shown to be safe and effective, Frazier said.
A collaboration with International AIDS Vaccine Initiative Inc., a nonprofit scientific research organization, aims to develop a vaccine by adapting the so-called recombinant vesicular stomatitis virus technology behind Merck’s Ebola shot.
IAVI scientists in Brooklyn are researching the experimental shot, which is receiving funding from BARDA, and may enter human studies later this year.
“We start with a platform we understand,” Frazier said. “We understand how it behaves, how to make it, how to scale it up, because we have experience with that platform.”
Gerberding said the “lessons learned” through Merck’s Ebola virus research and development research and development make her reluctant to over-promise on how quickly a vaccine can be delivered.
“We really have to think about how do we create a safe vaccine for the world, and that is a challenge we have never accomplished for any vaccine-preventable disease. So we have to be really realistic about that,” she said.
Measles Vector
Merck will also buy Themis, a privately held biotechnology company, for an undisclosed sum, gaining another vaccine candidate that uses the existing measles virus vector platform. Development of the shot has received support from the
Frazier wouldn’t say how much any successful immunization would cost, but added that Merck is committed to supplying “affordable access” and would seek partners to manufacture enough to meet global demand. Regardless of timeline, “we’re prepared to do that,” he said.
Covid-19 Pill
An early stage clinical trial showed EIDD-2801 was well-tolerated, while preclinical studies found it induced mutations in a broad range of coronaviruses, causing them to make catastrophic errors when they replicate. Remdesivir, the antiviral infusion developed by
EIDD-2801 may potentially arrest infections at an earlier stage, he said, adding that it also appears easier to synthesize and manufacture on a large scale. In addition, “importantly, this compound can be given in pill form, which would make it easier to use,” he said.
Delayed Succession Plans
Frazier, 65, said the pandemic has delayed plans for him to step down, as well as to find a replacement for R&D leader Roger Perlmutter, a former president of the
“We’ll get back to normal at some point,” Frazier said. “I’m totally confident in the high quality people who we have behind me and behind Roger Perlmutter.”
