Health Officials Strongly Recommend COVID-19 Vaccine Boosters for All Adults

The Centers for Disease Control and Prevention (CDC) strongly recommended today COVID-19 boosters for all adults who have been fully vaccinated with the COVID-19 Pfizer or Moderna vaccines at least six months ago.  People can choose a different COVID-19 vaccine than their original series as a booster.  The CDC previously recommended a booster for all adults who received the Johnson & Johnson vaccine at least two months ago.

As there is emerging evidence that immunity from the COVID-19 vaccine may wane over time, it is recommended that adults should get their booster now, if eligible.  The Alameda County Public Health Officer, Dr. Nicholas Moss, indicated that a rise in COVID-19 cases is expected "as people gather with friends and family indoors and travel for the holidays." 

The Pfizer and Johnson & Johnson booster doses are the same dosage as the original vaccine received in the series, while the Moderna booster dose is half the dosage of the original vaccine series.  A person can receive their booster from any location, not necessarily where they received their initial vaccine series.  Booster appointments are also available through
