President-elect Joe Biden and his advisers plan this week to demonstrate a far more assertive strategy against the coronavirus than President Trump’s, and Biden may take a more proactive role in coming weeks in congressional negotiations over an economic stimulus package.

Biden’s proposals, some of which were posted on his new transition website, include aiming to secure funds for ramping up coronavirus testing, acquiring additional protective equipment such as masks and gowns, and investing $25 billion in vaccine manufacturing and distribution.
