COVID-19 Vaccine Availability

COVID-19 vaccines are available to all eligible beneficiaries. Fort Irwin is currently administering Pfizer and Moderna. Both vaccines are safe and effective against COVID-19 and its variants.

The CDC recommends COVID-19 vaccination for everyone 6 months and older. FDA-approved or authorized COVID-19 vaccines are currently available to all U.S. citizens and residents. Visit the CDC website for more information.
  • COVID-19 vaccines are safe, effective, and free.
  • Getting the vaccine can reduce the risk of severe disease, hospitalizations and long-term complications for COVID-19
  • For children, the vaccine can also curb community transmission and reduce disruptions to in-person learning activities.
To learn more, visit the CDC website to get answers to frequently asked questions, see Interim Clinical Considerations, and bust myths about vaccines.

Future dates for vaccinations

COVID-19 vaccines are available to eligible beneficiaries ages 6 months and older TUESDAYS ONLY 9 a.m. to 3 p.m. in the Immunization Clinic in Primary Care by walk-in only.

DOD COVID-19 Vaccine Mandate

The DOD now requires COVID-19 vaccines for all members of the Armed Forces under DOD authority on active duty or in the Ready Reserve, including the National Guard, who are not fully vaccinated against COVID-19.  
  • If you’re a service member and you’ve received a COVID-19 vaccine from a non-DOD provider, make sure to update your medical records.
  • If you haven’t received your COVID vaccine yet, schedule your vaccine as soon as you can.
  • See COVID-19 vaccine schedule below for more information.

The DOD already requires all ADSMs to get other types of vaccines before they join the military. There are very narrow religious and medical exemptions available on a case-by-case basis. If you have questions, contact your unit commander.

Additional Dose for Immunocompromised

People who are moderately to severely immunocompromised are recommended to get an additional dose of an mRNA COVID-19 vaccine (i.e., Pfizer-BioNTech or Moderna).

Booster Doses (1st and 2nd)

Certain groups of people are recommended to get a booster shot. Weed ACH is offering a second booster to adults 50 years of age and older and immunocompromised beneficiaries.

How do I know if I should receive a COVID-19 Vaccine booster dose?

If you received the Pfizer-BioNTech or the Moderna COVID-19 vaccine for your two-dose primary series, the CDC recommends some individuals receive a single booster dose at least six months after the second dose  >>Learn more
Eligible beneficiaries interested in receiving a booster dose can make an appointment at https://go.usa.gov/xHgSE 
Fort Irwin currently only offers Pfizer or Moderna boosters. For any questions or concerns, please speak with your primary care provider.

Are You a DOD Civilian Employee?

All DOD civilian employees must be fully vaccinated by Nov. 22, 2021, subject to exemptions as required by law. >> See SecDef Memo

  • Employees are considered fully vaccinated 2 weeks after completing the second dose of a two-dose COVID-19 vaccine or 2 weeks after receiving a single dose of a one-dose COVID-19 vaccine.
  • New DoD civilian employees must be fully vaccinated by their entry on duty (start) date or Nov. 22, 2021, whichever is later.

COVID-19 Vaccine for Children

Getting your children vaccinated can help protect them against COVID-19, as well as reduce disruptions to in-person learning and activities by helping curb community transmission. Vaccination also reduces risk of:
  • Severe disease
  • Hospitalizations
  • Long-term COVID-19 complications
The CDC recommends that children ages 12 to 15 receive a Pfizer-BioNTech COVID-19 vaccine and children ages 5 to 11 receive a pediatric Pfizer-BioNTech COVID-19 vaccine. The Pfizer-BioNTech pediatric COVID-19 vaccine is administered as a 2-dose series, 21-days apart. Each dose contains 10mg of the vaccine, which is one third the adult dose.
If you are unsure whether the vaccine it right for your children, we recommend you discuss your child’s medical conditions, including prior reaction to vaccines, with a medical provider.

Q: Do I have to get my COVID-19 vaccine on post? (Updated 3/25/21)

A: No. Those who choose to go into the local communities to receive either their first or second doses should:

1) Ensure they are receiving the same brand of COVID-19 for both their first and second doses. Fort Irwin is currently giving doses of the Moderna COVID-19 vaccine. 
2) Provide us with the documentation, so we can add it to their electronic health record. It also allows us to update our trackers to ensure we are accounting for the right number of people who still want to receive the vaccine from WACH.
Q: I have questions about the safety or efficacy of the Moderna COVID-19 Vaccine. Where can I get more information?
A: Please visit one of the following government website for more FAQs about the COVID-19 vaccine:
Health.mil FAQs
Q: I have already received one dose of the Moderna or Pfizer COVID-19 vaccine. Can I receive my second dose at Fort Irwin?
A: We request that you visit the same location for both doses. It is also important to note that those who received the Pfizer COVID-19 vaccine cannot receive the Moderna COVID-19 vaccine as their second dose, and vice versa.  If you recently PCS to Fort Irwin and received either the Pfizer or Moderna COVID-19 vaccines at your previous duty station, we will need verification from your immunization card and medical record to provide you the 2nd dose.
Q: Is there a phone number I can call for additional questions?
A: At this time, we ask all COVID-19 vaccine appointment-related questions to be sent to usarmy.irwin.medcom-wach.mbx.covid@mail.mil.  Please do not call our nurse-staffed COVID-19 advice line for appointment-related questions as we want to ensure sick patients are able to get through to the on-call nurses for immediate medical support.

What Happens Next?

Once you receive the vaccine, if you experience any side-effects or have any questions, please don’t hesitate to contact us directly or contact the MHS Nurse Advice Line.
