Walgreens announced that eligible individuals can now receive Moderna and Johnson & Johnson (J&J) COVID-19 vaccine booster shots in stores nationwide following the Food and Drug Administration (FDA) Emergency Use Authorization and new guidance from the Centers for Disease Control and Prevention (CDC). This follows FDA authorization of a Pfizer booster dose on Sept. 24. As part of this new guidance, eligible populations may also choose to receive a dose different from the one they received for their initial series.
