Shares of Moderna, Inc. and Novavax, Inc. jumped premarket Tuesday, rising as much as about 6% and nearly 8%, respectively, as retail investors turned their focus toward vaccine makers amid growing concerns about bird flu.

Brookline Capital Markets analyst Leah Cann suggested that the increased attention on these stocks could be linked to the latest health worries that have sparked fears of another pandemic, according to Reuters.

On Monday, the United States reported its first human death from H5N1 bird flu in Louisiana. While most of the other 65 known U.S. cases have been mild, a severe case in Canada has further heightened alarm.

The U.S. government has been preparing for potential outbreaks, awarding $306 million last week for avian flu preparedness, including monitoring and testing farmworkers.

Novavax, meanwhile, has conducted pre-clinical tests on vaccines targeting multiple H5N1 strains, but updates on its progress remain limited.
