Pfizer-BioNTech booster shots now available for eligible Guam residents




By Pacific Island Times News Staff

The government of Guam today announced that booster shots are now available at the University of Guam Calvo Field House for people who had a normal immune response to the first two doses of the Pfizer-BioNTech Covid-19 vaccine, but because of time, antibody levels are beginning to wane.


The Pfizer-BioNTech Covid-19 vaccine is the only FDA-authorized vaccine to administer as a booster.


Pfizer Inc. said that data from the U.S. and Israel suggest that the efficacy of its Covid-19 vaccine wanes over time, and that a booster dose was safe and effective at warding off the virus and new variants.


The following groups of people are eligible for a booster shot of Pfizer-BioNTech if they completed the Pfizer-BioNTech series (first two doses) and it has been 6 months or more since the second dose:

  • Anyone age 65+

  • Anyone age 18 - 64 with underlying medical conditions

  • Anyone 18 - 64 with an elevated risk of COVID-19 exposure and transmission due to their occupation (healthcare workers, law enforcement, fire, K-12 teachers and support staff, university faculty, daycare employees, food and agriculture workers, manufacturing workers, USPS workers, corrections workers, public transit workers, grocery store workers)
