The president criticized the FDA this week for not giving emergency use approval to an experimental treatment for COVID-19. Scientists argue that the therapy still lacks sufficient evidence.

The National Institutes of Health has asked the Food and Drug Administration to delay allowing the use of convalescent plasma to treat COVID-19 because the proof of its effectiveness is weak.

Adjuvants play a crucial role in many vaccines' effectiveness. Some scientists say there needs to be more research into developing a wider variety of adjuvants because of how important they are.

Studies involving COVID-19 vaccine candidates in monkeys show promise of an effective vaccine, but it will take large-scale human trials to know for sure if they work.

Two potential coronavirus vaccines started their final phase of testing Monday. Each trial will include up to 30,000 volunteers.

A COVID-19 vaccine candidate developed by the U.S. company Moderna and the National Institutes of Health starts its final phase of testing. It's one of a handful of candidates to reach this stage.

As several new COVID-19 vaccines enter human trials, multiple intelligence agencies say Russian hackers are targeting organizations developing the vaccines.

NASA is sending a six-wheeled rover to Mars to look for signs of microbial life stored in the rocks at Jezero crater. The rover is also the first step in bringing samples of Martian rock to Earth.

The UAE turns 50 next year, and on Tuesday a craft will be launched to orbit Mars to celebrate. Building a Mars probe also provided a focus for expanding the country's technological capabilities.

The federal government on Tuesday announced grants for the development and manufacture of vaccines and treatments for COVID-19 totaling over $2 billion.

Dr. Elias Zerhouni was head of the National Institutes of Health under President George W. Bush. He says the Trump administration's response to the pandemic has not protected the American people.

Some of the technology behind coronavirus vaccine development dates back to the first vaccines; other techniques are much newer. Here are some of the approaches.

Some of the technology behind coronavirus vaccine development dates back to the first vaccines; other techniques are much newer. Here are eight top strategies scientists are pursuing.

The approach of taking blood plasma from people who have recovered and giving it to patients still suffering from a disease has been used for centuries. Now it's being used on COVID-19 patients.

Cattle may turn out to be of help in the coronavirus pandemic. A South Dakota biotech company is using cows to create antibodies that could then be used for disease prevention or treatment.

A low-cost anti-inflammatory drug appears to reduce the risk of death in patients with COVID-19. The promising result comes from a large study of therapies being conducted in the U.K.

A South Dakota biotech company is using cows to create antibodies that could then be used for disease prevention or treatment. The cows have been given the genes to make a human-like immune system.

Emergency use authorization makes it easier for doctors to use a drug in a manner not specifically approved by the Food and Drug Administration. The FDA granted these drugs this status in March.

While only remdesivir has been scientifically shown to help treat COVID-19, it is not a particularly effective drug. More drugs like it and fundamentally different ones are in the pipeline.

There is only one drug that researchers say has been scientifically shown to help COVID-19: remdesivir. But it is not proven to reduce mortality. So, researchers keep looking for other treatments.
