Vaccines alone won’t end the COVID threat
Treatments are part of the “belt-and-suspenders” approach, along with vaccines to combat COVID-19, Dr. Doernberg said.
“We’re not going to eradicate COVID,” she said. “We’re still going to need treatments for people who either don’t respond to the vaccine or haven’t gotten the vaccine or developed disease despite the vaccine.”

Oral formulations are desperately needed, agreed Kenneth Johnson, PhD, professor of molecular biosciences at the University of Texas at Austin.
Right now, remdesivir treatments involve patients being hooked up to an IV for 30-120 minutes each day for 5 days. And the cost of a 5-day course of remdesivir ranges from $2340 to $3120 in the United States.
“We’re hoping we can come up with something that is a little bit easier to administer, and without as many concerns for toxic side effects,” he said.
Dr. Johnson’s team at UT-Austin recently made a key discovery about the way remdesivir stops the replication of viral RNA.
The understanding of where the virus starts to replicate in the infection chain of events and how and where it reacts with remdesivir might lead to the development of better, more concentrated pill forms of antivirals in the future, with fewer toxicities, he said.
The team used a lab dish to recreate the step-by-step process that occurs when a patient who is infected with SARS-CoV-2 receives remdesivir.
The discovery was published online in Molecular Cell in January and will be printed in the April issue of the journal.
The discovery won’t lead to an effective COVID-19 pill for our current crisis, but will be important for the next generation of drugs needed to deal with future coronaviruses, Dr. Johnson explained.
And there will be other coronaviruses, he said, noting that this one is the third in 20 years to jump from animals to humans. “It’s just a matter of time,” he said.
