New COVID shots are cleared for shipping, but a fight over the FDA's advisory panel leaves insurance coverage uncertain — good for people wanting the shot, murky for anyone counting on it being free.

• The FDA signed off on updated COVID vaccines from Pfizer, Moderna, and a different type from Sanofi, with doses reaching local doctors within days.
• Formulas change every year as the virus mutates, same as flu shots.
• Insurers normally pay for any vaccine an FDA expert panel approves, but Health Secretary Robert Kennedy swapped out panel members and a court threw out those appointments — so it is unclear what insurers will do.
• A federal judge in Boston, Indira Talwani, issued a fresh temporary block on Trump's push to limit mail-in voting, saying voter rights groups are likely to win their claim that planned Postal Service moves are unconstitutional.
• Trade talks with Canada remain frozen; Canada's trade minister suggested the U.S. could show good faith by dropping its challenge to Canadian laws making French an official language.

Outlook: Watch whether insurers keep covering the new shots and whether the mail-voting block survives appeal.
