Welcome to FirstHealth’s COVID-19 Vaccine Booster Registration

Pfizer-BioNtech boosters are available to people who have been fully vaccinated with the Pfizer-BioNTech (COMIRNATY) vaccine for six months or more and who are:  

  • 65 years or older,
  • Residents in long-term care,
  • 18 years or older with underlying medical conditions; or, 
  • 18-64 years and work in high-risk settings like healthcare workers, teachers and childcare providers or food workers. 

In addition, moderately to severely immunocompromised people are recommended to receive an additional dose of the same brand of vaccine at least 28 days after they’ve completed their initial two-dose series to help increase the body’s immune response.
