The big picture: The administration on Wednesday announced that Americans who received a Pfizer or Moderna vaccine should expect to be offered a booster shot eight months after their second dose.

• The move seeks to curb declining vaccine effectiveness over time as the Delta variant continues to spread nationwide.

• Officials are planning to offer the booster shots to eligible Americans starting the week of Sept. 20.

• A booster shot for individuals who received the single-dose J&J vaccine is also likely to be recommended, but officials are waiting for more data to come out over the coming weeks.
