Novavax starts human trials for coronavirus vaccine

• "We are in parallel making doses, making vaccine in anticipation that we'll be able to show it's working and be able to start deploying it by the end of this year," he added.

Of note: Tests on animals indicated the vaccine is effective in low doses, according to Novavax.

How it works: "Novavax used genetic engineering to grow harmless copies of the coronavirus spike protein in giant vats of insect cells in a laboratory," AP reports. "Scientists extracted and purified the protein, and packaged it into virus-sized nanoparticles."

What's next: The results of this first phase of the trials are expected in July.

• Novavax plans a second phase of the study in multiple countries including the U.S. if the first proves fruitful. This would also examine whether COVID-19 is reduced by the vaccine.

The big picture: There are at least 92 vaccines under development for COVID-19. 22 of these are experimental DNA- or RNA-based vaccines that provide the most hope for speedy development, per Axios' Alison Snyder and Eileen Drage O'Reilly.

By the numbers: COVID-19 has killed more than 346,000 people worldwide, including over 98,000 in the U.S. Almost 5.5 million have tested positive for the virus — over 1.6 million of whom are in the U.S.
