Frequently Asked Questions

At Montana VA, we know Veterans, their families and caregivers have a lot of questions. Here are some of our most commonly asked questions.

COVID-19 Booster Shot Questions

Montana VA is now giving COVID-19 Booster shots to Montana Veterans. Our first booster clinic will be held in Billings at the Benjamin Charles Steele VA Clinic on Nov. 4 and will be followed by a three-day booster clinic for Helena-area Veterans at the National Guard Aviation Readiness Center near Helena Regional Airport from Nov. 8-10 before expanding to locations in Havre, Lewistown, Missoula, Butte, Kalispell, Great Falls and Bozeman.

Why should I get a COVID-19 vaccine booster shot?

The initial vaccine remains highly effective in reducing the likelihood of infection and preventing severe illness, hospitalization, and death among those infected. The purpose of a booster shot is to “boost” antibody protection when it has decreased over time.  

What is the difference between a third dose and booster shot of Moderna? 

  1. A booster shot is for people whose immune response may have weakened over time. We offer boosters to people who completed an initial COVID-19 series with Pfizer or Moderna COVID-19 vaccines if they had their second dose at least six months ago and are 65 years or older, 18 and older with underlying medical conditions, or an adult living in a long-term care setting or living or working in a high-risk setting. The CDC also recommends a booster for adults who received a J&J vaccine at least two months ago.  CDC's recommendations allow a mix-and-match dosing for booster shots.  


  1. A third dose is for people who may not have had a strong enough immune response from the first two doses. We offer third doses to people who are moderately to severely immunocompromise and received either Moderna, Janssen (J&J), or Pfizer COVID-19 vaccines. This includes those with organ transplants and those diagnosed with conditions that are considered to have a similar level of immunocompromise. Data shows they are more at risk of serious, long-term illness from COVID-19. They may benefit from a third dose to make sure they have enough protection against COVID-19. 


Where can I get a booster shot?

Currently, the Montana VA is hosting booster clinics across the state. Clinic information is subject to change.

 Veterans can also contact their local VA Clinic for more details. 

If you choose to get your booster shot outside of VA, you can locate a vaccine site at - Search for COVID-19 vaccine locations. Make sure to bring your CDC COVID-19 Vaccination Record Card when you go, no matter where you choose to get a booster!

I received an initial series/dose of the COVID-19 vaccine, do I need proof of age or that I am high risk of severe COVID-19 to get the booster?


If you receive your care from the VA, we have record of your age and your risk of severe COVID-19. We will work to reach out to individuals at highest risk from COVID-19 to make sure they are aware of the recommendation for a booster. We trust Veterans, their families and caregivers, and our staff. We will accept self-reporting of your high-risk condition or occupation.  


You should bring your vaccine card or record with you to your visit so we can make sure you get your booster at the right time.

The CDC says I get to choose which vaccine I receive as a booster. Do I tell the people when I sign in, or do I tell the nurse prior to giving me the shot?

  1. Montana VA is authorized to give the Moderna COVID-19 vaccine.  

  1. In the past the Montana VA did provide some J&J vaccinations. However, at this time, we cannot guarantee that we will have supplies of J&J for boosters. 

What are the differences in the vaccines?

  1. The J&J vaccine a traditional carrier vaccine. It involves injecting individuals with an inactive adenovirus, or common cold virus, that carries the genetic code of the coronavirus spike proteins. The body’s immune system is then trained to create antibodies and memory cells that protect against the actual virus. 

  1. The Pfizer and Moderna vaccines were developed using messenger RNA technology. That involves delivering a piece of genetic code from the coronavirus to host cells in the body. The body then makes copies of the virus’s spike proteins, which stimulates the immune system to produce antibodies and develop memory cells.  

Are there side effects when getting a booster shot?

  1. Individuals have reported minor side effects after receiving a third shot of the Moderna or Pfizer vaccine. They include: pain at the injection site, fatigue, muscle pain, headache and fever, but are often not long-lasting. 

  1. Data was more limited for the J&J vaccine, but some people reported fever, fatigue and headache after receiving a second dose of that vaccine. 

What else should I know about getting my booster shot?

  1. Bring your COVID-19 vaccine card at the time of your appointment.  

  1. Share your booster status with your Primary Care team if you get your booster outside the VA.  

  1. Make sure you received your second dose of Moderna at least six months ago or your single dose of Janssen (J&J) vaccine two months ago.  

  1. Masking is required inside all Montana VA sites and clinics.
