Vaccine Status Report

UPDATE: 4/29/2021
The CDC and FDA have once again recommended use of the Johnson & Johnson vaccine, after investigating reports of rare side effects. Three Rivers Hospital has about 1,000 doses of Moderna and 100 doses of Johnson & Johnson. Our team is working on planning the next vaccination event. If you would like to register for the vaccine, please click the red button below, or call the COVID-19 Vaccine Registration Hotline at 1-866-458-0169. Help is available in English and Spanish.

Step 1

Are you a resident of Okanogan County or north Douglas County (Bridgeport and Mansfield)?

Due to the limited number of vaccine allocation to our hospital, we are prioritizing our full-time residents within Okanogan-Douglas County Public Hospital District 1 and Okanogan County. If you do not live within our district or county, please do not register with us at this time. We apologize for any inconvenience.

Step 2

Complete Vaccine Registration 

Okanogan County Emergency Management has launched a new centralized registration and scheduling system for all Okanogan County residents.
Please click the red button on the right to complete the online COVID-19 vaccine registration form, including your preference of which hospital or clinic where you would like to receive the vaccine.

As vaccine becomes available, those who have registered in this centralized system will be contacted in the order of when the registration was received. Scheduling your vaccine may take a few weeks or longer, depending on supply.

  • You are welcome to register at any time, regardless whether you are described in the current vaccine eligibility phase or not.
  • This vaccine has not yet been approved for use on children under the age of 16.
  • You will only be contacted to schedule a vaccine when you become eligible.
    • All adults will be eligible to receive the vaccine effective April 15, 2021 and should register now. The Moderna vaccine has been approved for all age 18 and older, and Pfizer has been approved for age 16 and older. In Okanogan County, North Valley Hospital offers the Pfizer vaccine.

Step 4

After your registration form has been received, you will be contacted either by hospital staff or by an automated system once you’re eligible to receive the vaccine and supply is available.

Depending on your eligibility, the state’s supply, and your preferred location, the wait could be a couple weeks or longer. Please be patient and know that your registration will not be removed for any reason, nor will your place in line be changed.

Frequently Asked Questions

Q: How do I know which phase I qualify for?

A: The Governor’s Office has opened up vaccine eligibility to everyone age 16 years and older.

You can register for the waiting list now by clicking the red button under Step 2 on this page, or by calling the COVID-19 Vaccine Registration Hotline at 1-866-458-0169. Please be advised that there may be a bit of a wait before you are contacted for an appointment, depending on vaccine availability and when events are scheduled.

Q: Why do I need an appointment? Why can’t I just walk in and ask for the vaccine?

A: The current COVID-19 vaccine arrives in a multi-dose vial and is administered in groups of 5 or 10 people, depending on the brand. To help as many people receive the vaccine as quickly as possible and avoid wasting valuable vaccinations, groups of people are scheduled for quick appointments. Each appointment includes checking in, receiving the vaccine, and 15 -30 minutes of monitoring for any allergic reactions.

Q: I’ve registered for the vaccine, but I have not been contacted for an appointment. Why is that?

A: We schedule appointments when we have vaccine supply. Due to how the vaccines are packaged (in vials of 5 or 10 doses), we schedule people to receive them in groups. This means we typically hold larger vaccination events, which take some time to plan. As soon as we have new vaccination event dates, we use Okanogan County’s centralized scheduling system to send out automated messages offering appointments.

If you receive one of these automated messages, please listen to or read the entire message. You will be offered an appointment date and time, and you will be given the option to choose whether you can attend by responding directly to the message. This helps us keep all appointments organized in one place, so we can be sure to have enough vaccine for everyone.

Q: What happens at the appointment?

A: If you are obtaining the vaccine at Three Rivers Hospital or Three Rivers Family Medicine, please come in through the main entrances. You will be let in and screened for temperature and COVID-19 symptoms. At that point, you can check in with the team waiting to help you.

If you are attending a mass vaccination event in Pateros or at the Okanogan County Fairgrounds, please note that these are drive-thru events. You will not need to get out of your vehicle. Please wear a mask and a short-sleeved shirt.

You may have a brief wait before it’s your turn to be vaccinated. Receiving the shot is a quick process! Once you’re done, we’ll ask you to wait for 15-30 minutes to monitor you for any allergic reaction. The wait time depends on your known allergies and other health factors we will ask you about at the time of your appointment.

During the first appointment, we’ll schedule your second dose if you receive the Moderna vaccine. The date will be printed on the back of your vaccination card, so don’t lose it! Due to the timing and effectiveness of the vaccine, it’s very important to not miss the second appointment.

If you receive the Johnson & Johnson vaccine, you will not need a second dose.

If you have no reaction to the vaccine during your designated wait time, you’ll be cleared to leave.

Q: How do I sign up to receive the vaccine?

A: We strongly recommend signing up to receive a COVID-19 vaccine. You can access the online registration form by clicking the red “COVID-19 Vaccine Registration Form” button on this webpage. You may also register by phone (English and Spanish) by calling 1-866-458-0169.

When registering, you’ll be given the option of your preferred vaccine brand and your preferred location (South County, Methow Valley, Mid-County, and North County). Based on those preferences, you will be offered an appointment by an automated scheduling program via the contact options you provided (email, phone, and/or text). These messages go out as vaccine supply is available and events are scheduled. If you are offered an appointment on a day you can’t make it, you will be given the option to decline but stay on the waiting list.

Q: What if I can’t make it to my appointment, or what if I missed it due to unforeseen circumstances?

A: If you need to reschedule your first appointment, please call us Monday-Friday, 8 a.m. – 7 p.m., at least 24 hours before your appointment at (509) 689-2517.
This will allow us to schedule others waiting who can step into your vacated slot.

If you missed your first dose appointment due to unforeseen circumstances, you don’t need to do anything. We still have your information on file and will contact you as soon as we can to reschedule you.

Reminder! Due to the timing and effectiveness of the vaccine, it’s very important to not miss the second appointment. It is possible to receive the second dose of the Moderna vaccine up to six weeks after the first dose, without affecting the efficacy of the vaccine.

Q: What is the cost for the vaccine?

A: This is a free service to the community, so there are no out of pocket charges. However, we may request your insurance information to bill a small administrative fee for each dose. If you do not have health insurance, our team can help you secure coverage through the Health Resources and Services Administration (HRSA).

Q: Which vaccine is available at Three Rivers Hospital?
A: We have received the Moderna vaccine. This is delivered in two doses, spaced 28 days apart. We are able to order more each week from the state.

Q: Will Three Rivers Hospital offer the new Johnson & Johnson one-dose vaccine?
A: As of March 2, we do not yet know if we will receive that vaccine. Please feel free to check back on this page in the coming weeks for any updates on this. In the meantime, here is an article from KING-5 about the rollout of the Johnson & Johnson vaccine in Washington state: CLICK HERE

Q: How does the vaccine work?
A: The Washington State Department of Health has a minute-long video explaining how the vaccine works in your body.



Q: What are the normal side effects of the Moderna vaccine?

A: From the Washington state Department of Health website: “Like some routine vaccines, the most common side effects are a sore arm, tiredness, headache, and muscle pain. These symptoms are a sign that the vaccine is prompting an immune response. Data from clinical trials showed the following:

  • Ninety percent of people reported pain at the injection site
  • Seventy percent of people reported tiredness and headache
  • Sixty percent of people reported muscle pain

“For most people, these side effects occurred within two days of getting the vaccine and lasted about a day. Side effects were more common after the second dose than the first dose.

“You may see some rumors about untrue side effects online or on social media. Make sure any time you see a claim about a side effect that you check the source of that claim. This video can teach you more about how to figure out if a claim online is true or not.”
