COVID-19 Vaccine Boosters 

  • Populations eligible for boosters now include:
    • People age 18+ who completed their primary series of J&J at least 2 months prior
    • People age 65+ who completed their primary series of Pfizer or Moderna at least 6 months prior
    • People age 18-64 who completed their primary series of Pfizer or Moderna at least 6 months prior AND are at high risk of COVID-19 due to underlying health conditions, residence in long-term care settings, or working or living in high-risk settings
  • ‘Mixing and matching’ is authorized for boosters, meaning that a booster dose of any authorized COVID-19 vaccine may be administered as a heterologous booster following completion of primary series with any authorized COVID-19 vaccine
    • An eligible individual who received a Pfizer primary series may receive a Pfizer, Moderna, or J&J booster at least 6 months after completing their primary series
    • An eligible individual who received a Moderna primary series may receive a Pfizer, Moderna, or J&J booster at least 6 months after completing their primary series
    • An eligible individual who received a J&J primary series may receive a Pfizer, Moderna, or J&J booster at least 2 months after completing their primary series
  • Updated product details including vial type and dosage for the three vaccines are as follows:
    • Moderna booster doses will be 0.25mL, which is ½ the dosage of a primary series dose (0.5mL)
    • Additional doses for immunocompromised individuals shall remain a full dose (0.5mL)
  • Pfizer boosters will continue to have the same dosage as a primary series dose (0.3mL)
  • Additional doses for immunocompromised individuals shall remain a full dose (0.5mL)
  • J&J boosters will have the same dosage as a primary series dose  (0.5mL)
  • Guidance on 3rd doses for immunocompromised populations remains in place.

ACIP recommends the following individuals be considered for a third dose of an mRNA vaccine, if they received it as the first dose:

  • Organ transplant recipients taking immunosuppressive therapy
  • Recipient of stem cell transplants (CAR-T-cell or hematopoietic) within two years or taking immunosuppressive therapy
  • Active/recent cancer treatments for tumors or hematologic malignancies
  • Advanced or untreated HIV infection
  • Persons taking medications that weaken the immune system - high-dose corticosteroids (i.e., ≥20mg prednisone or equivalent per day), alkylating agents, antimetabolites, transplant-related immunosuppressive drugs, cancer chemotherapeutic agents classified as severely immunosuppressive, TNF blockers, and other biologic agents that are immunosuppressive or immunomodulatory
  • Moderate or severe primary immunodeficiency (e.g., DiGeorge, Wiskott-Aldrich syndromes)

 Implementation Considerations:

  • The additional dose should be the same mRNA vaccine as the primary series
  • Alternate mRNA product can be used if primary series product not available
  • The additional dose should be administered at least four weeks (28 days) after completion of the initial primary series
  • Immunocompromised people (including those who receive an additional mRNA dose) should be counseled about the potential for reduced immune response to COVID-19 vaccination and need to follow prevention measures


Please fill out Pre-vaccination Checklist and bring it to your appointment.

We are seeing patients in the office. We have taken step to ensure we do everything possible  to keep our patients and our staff healthy. We offer Tele-visits for people who do not want to come or do not need to come to the office.

We have started healow® CHECK-IN

How it works, step by step

  • The day before a patient’s appointment, healow CHECK-IN automatically sends a text reminder to the patient’s phone and to the healow app. By clicking the reminder link, patients can confirm their appointment and start the check-in process. 
  • During check in, patients review their demographics, confirm their insurance coverage, sign consent forms, fill out questionnaires, and review medications, allergies, hospitalizations, and surgical histories.
  • When patient arrives in the parking lot of the office, they can click “I have arrived”. When the doctor is ready, the medical assistant will come out to the parking lot or call you  and bring the patient right into the room.

Office Policies during  Coronavirus Pandemic:

  • Face mask/face coverings is required to enter the office (Please bring your own mask)
  • Upon entering the office you will be provided with hand sanitizer and asked to sanitize the hands
  • All patients, visitors and staff will be screened for COVID-19 symptoms and have their temperature checked
