RMKS/ 1. Purpose. This NAVADMIN provides guidance for Active and Reserve
Component uniformed Navy personnel. Reference (a) recommends vaccine
boosters for Service members, DoD civilian employees, eligible DoD
beneficiaries, and select contractor personnel. If needed, specific guidance
beyond reference (a) for non-uniformed Navy personnel will be released
separately. Food and Drug Administration (FDA) approved vaccine regimens
have proven to be safe and effective in preventing serious illness or
death. Ongoing studies, however, have revealed that vaccination immunity
decreases over time and the Centers for Disease Control and Prevention (CDC)
recommends a vaccine booster for everyone age 16 and older.
2. Applicability. This guidance applies to Active and Reserve Component
uniformed Navy personnel who completed the primary Pfizer-BioNTech/Comirnaty
or Moderna COVID-19 vaccine series (i.e., received the second dose of
the vaccine) more than 6 months ago, or who received a primary dose of the
Johnson & Johnson/Janssen COVID-19 vaccine more than 2 months ago.
Although this NAVADMIN specifically applies to uniformed Navy personnel,
all personnel over the age of 16, including government civilians, are
encouraged to obtain a vaccine booster.
3. Policy Guidance. Although not mandatory, the COVID-19 vaccine booster
is strongly recommended. Because all studies are converging on the need for
a vaccine booster to ensure enduring protection, it is essentially becoming
the next-shot in a series and will likely become mandatory in the near
With the evolution of additional COVID-19 variants, e.g., Omicron, this
NAVADMIN encourages exercising prudence to ensure continued protection.
3.a. Conditions to be fully vaccinated. The vaccine booster is a time-based
reinforcement of the initial vaccine in order to prevent decreasing immunity.
The vaccine booster is not currently a requirement to be fully vaccinated per
references (a) through (f). Individuals are still considered fully
vaccinated 2-weeks after receiving the second dose in a two-dose initial
vaccine series (e.g., Pfizer-BioNTech/Comirnaty, Moderna vaccines), 2-weeks
after receiving a single-dose vaccine (e.g., Johnson & Johnson/Janssen
vaccine), or having received a World Health Organization (WHO) Emergency Use
Listing (EUL) initial vaccine series.
3.b. Specific categories. Under CDC guidance, the below three categories
may ONLY receive a Pfizer-BioNTech/Comirnaty vaccine booster.
3.b.1. Individuals who have completed a primary vaccination series while
enrolled in an Institutional Review Board (IRB), FDA, National Institutes of
Health (NIH), or WHO clinical vaccine trial.
3.b.2 Individuals who are fully vaccinated with a WHO EUL vaccine.
3.b.3. Individuals age 16 or 17 who have completed the primary Pfizer-
BioNTech/Comirnaty vaccine series.
3.c. CDC-supported booster vaccines. With the exception of paragraph
3.b above, CDC guidance allows individuals to choose any COVID-19 vaccine
booster that has received either FDA licensure or Emergency Use Authorization
(EUA). The CDC allows mix and match dosing (i.e., taking different COVID-19
vaccines), taking into consideration an individuals preference, previous side
effects, and vaccine availability. The CDCs Advisory Committee on
Immunization Practices (ACIP) has stated a clinical preference for mRNA
COVID-19 vaccines (Pfizer/Moderna) over non-Mrna (Johnson &
Johnson/Janssen). Before receiving any booster shot, service members should
review that vaccines Fact Sheet for Recipients and Caregivers and contact
their Primary Care Manager with any questions or concerns.
3.d. Active and Reserve Component members may elect to receive a vaccine
booster from either a military or non-military vaccine site. To ensure
Medical Readiness Reporting System (MRRS) accuracy, service members who
receive the vaccine booster from a non-military site must provide their
immunization data to their command as soon as practicable, but not to exceed
five working days. The government website https://www.vaccines.gov/
lists locations as well as available appointments for COVID-19 booster shots
throughout the country.
3.e. International travel. A growing number of host countries now have
varying degrees of restrictions if more than six months have elapsed since
receiving the initial COVID-19 vaccine. Accordingly, a vaccine booster will
likely be needed to travel to, or avoid liberty restrictions in, these
countries. Nothing in this NAVADMIN supersedes existing national, state, or
local restrictions and requirements.
4. Responsibilities. Commanders, Commanding Officers, and Officers in
Charge will ensure this NAVADMIN is widely disseminated throughout all
