More COVID-19 vaccines in the pipeline as US effort ramps up

  |  

A huge U.S. study of another COVID-19 vaccine candidate got underway Monday as states continue to roll out scarce supplies of the first shots to a nation anxiously awaiting relief from the catastrophic outbreak.

Public health experts say more options in addition to the two vaccines now being dispensed — one made by Pfizer and its German partner BioNTech, the other by Moderna — are critical to amassing enough shots for the country and the world.

The candidate made by Novavax Inc. is the fifth to reach final-stage testing in the United States. Some 30,000 volunteers are needed to prove if the shot — a different kind than its Pfizer and Moderna competitors — really works and is safe.

“If you want to have enough vaccine to vaccinate all the people in the U.S. who you’d like to vaccinate — up to 85% or more of the population — you’re going to need more than two companies,” Dr. Anthony Fauci, the top U.S. infectious disease expert, told The Associated Press on Monday.

The coronavirus is blamed for about 1.8 million deaths worldwide, including more than 330,000 in the U.S. This has been the deadliest month of the outbreak in the U.S. yet, with about 65,000 deaths in December so far, according to the COVID Tracking Project.

The nation has repeatedly recorded more than 3,000 dead per day over the past few weeks.
