Don’t Forget Your Second Dose

Getting vaccinated protects yourself and those around you from COVID-19. It is important people who receive a two-dose vaccine (Pfizer-BioNTech or Moderna) complete the series as close to the recommended time interval as possible.

  • If you received the Pfizer vaccine, you should get your second shot three weeks (or 21 days) after your first.
  • If you received the Moderna vaccine, you should get your second shot four weeks (or 28 days) after your first.

Across Washington, as of April 25 about 13% of people who received one dose of a two dose vaccine were overdue for their second dose by more than one week. We want this number to be as close to zero as possible to ensure the vaccine is fully effective and best protects people and communities.

Recently the Centers for Disease Control and Prevention (CDC) released data regarding overdue second doses. According to the CDC, nationwide 8% of people were overdue for their second dose. These national numbers are different from the state numbers due to the way the data were analyzed. DOH only considers people overdue if they miss the window and have only received one dose of a two-dose vaccine; whereas the CDC counted people who had completed the series.
