Othena Appointment FAQS

How do I make appointments over the phone?
People must schedule their own appointments via the web portal or the phone app.

Who can currently make appointments through Othena?
The County is currently prioritizing Phase 1A, Phase 1B, and those who are 65 years of age and older in accordance with current State guidelines. New registrants to Othena can now answer questions to determine which phase they are in during registration.

Is proof of immigration status required to register for a vaccine in Othena?
Immigration status is not checked at any time during the COVID-19 appointment and vaccination process. The health of our community is the only concern.

Why is it taking so long to get an appointment in Othena?
Appointments are available through Othena based on vaccine availability. Vaccine availability remains the limiting factor in setting appointments. With more than 750,000 people registered in Othena, eligible individuals who registered for a vaccine may not be able to immediately receive an appointment since there are many more people than available doses of vaccine. Eligible users will receive email and app notifications to schedule appointments based on the time and date of registration. Please check your registered email address or Othena app profile daily, as well as your spam folder.

What should I bring to my appointment?
Dress appropriately for the weather and bring a valid photo identification and verification of your appointment through Othena. Proof of Orange County residence or employment is required. Healthcare workers must present an employee badge, letter from their employer, or other documentation or proof of their occupation. No payment is required to get vaccinated.

How long does the average vaccination appointment take?
The average vaccination appointment takes less than an hour, including 15 minutes of observation after receiving the vaccine. Please do not arrive more than 30 minutes before your scheduled appointment.

I cannot view the appointment times or locations on the Othena app.
Please ensure you have the most current version of the app. Otherwise; it is likely that you do not actually have an appointment.

I was not able to get an appointment through Othena. Can I just go to a County Super Point of Dispensing (POD) site to get vaccinated?
You will not receive a vaccination without an appointment. Please do not go to a Super POD site without an appointment, hoping to get an “extra” dose at the end of the day. There is no vaccine waste at the end of the shift, and there are no doses available to the public.

Vaccination Locations

Can I choose where I receive my vaccine with Othena?
Othena is currently scheduling vaccination appointments at the Soka University, Disneyland Resort, and Anaheim Convention Center Super POD sites. Registered, eligible users will automatically receive notifications via email and through the Othena app as appointments become available at either location. Users may not have the option of choosing which site to attend, depending on the availability of the vaccine when the appointment is scheduled.

First Doses

The information from my first dose has not been entered into Othena. What should I do?
If you received your first dose through Othena, please email a photo of your CDC card to support@compositeapps.net and include the date and location of your first dose. Please be patient as we are working diligently to enter everyone’s information into the system.

Second Doses

How do I receive my second dose through Othena?
Othena tracks the date and vaccine type of your first dose to schedule your next appointment and ensure you receive the proper second dose. Your second dose will automatically be assigned following your first dose—you may choose to cancel or reschedule. Please regularly monitor and refresh your email or Othena app profile for appointment updates. Second doses of the Pfizer vaccination are recommended 21 or more days following the first dose and 28 or more days for the Moderna vaccination. However, if it is not feasible to adhere to the recommended interval, the guidelines allow for second dose administration up to six weeks (42 days) after the first dose.

How can I cancel or reschedule my second dose appointment?
Appointments for the second dose are scheduled automatically based on the time and date of the first appointment. This date is either 21 days (Pfizer) or 28 days (Moderna) out, depending on the vaccine. However, if it is not feasible to adhere to the recommended interval, the guidelines allow for second dose administration up to six weeks (42 days) after the first dose. You can reschedule in Othena no earlier than five days prior to their next appointment by going to the home page, clicking on View Details under your second appointment information; clicking on View Your Appointment at the bottom of the next screen; and then scrolling down and pressing the Reschedule Appointment button.

I received my first dose outside of Othena but would like to be entered into the system and scheduled for my second dose.

If you did not receive your first dose through Othena, then you must revisit your original vaccination site to receive your second dose. Vaccine providers are obligated to provide both a first and second dose in accordance with the vaccine manufacturer’s recommended schedule.  If the provider did not contact you to schedule your second appointment, then you should be able to go to that organization at the appropriate time and date to receive your second dose (21 days after the first dose for Pfizer and 28 days after the first dose for Moderna). If your clinic location was closed before you received your second dose, please send us the name and address so that we can report it.

I’ve lost my CDC card from my first dose appointment. Can I get my vaccination information entered into Othena?
If you do not have a copy of your CDC card, you should contact the location where you received your vaccination or speak with your primary care provider to receive a new one. Othena cannot enter your information into the system without a CDC card as proof of vaccination. Thank you for your understanding.

What do I do if Othena is showing first dose information in both the first and second dose fields?
This can happen if the information is incorrectly entered at the vaccination site. If this occurs, please call the hotline at (714) 834-2000 or email support@compositeapps.net so that it can be corrected.

I received my first dose from a County mobile clinic. How do I receive my second dose?
Individuals who received their first vaccine dose through a County mobile clinic will receive a second dose appointment notification through Othena. The plan is to return to the same mobile clinic site 21 to 28 days after the first dose, based on the type of vaccine dispensed.

I received my first dose from outside the County, can I get my second dose through Othena?
Individuals who received their first dose through a neighboring county or through their health system, employer, or other group will receive the second dose from the same source. Do not attempt to schedule through Othena or expect to receive a second dose at a County POD site.

Is Othena available in multiple languages?
English, Spanish, Vietnamese and Korean are supported via Othena.com and both the iOS and Android versions of the Othena app. Korean and Chinese translations are in the works. The COVID-19 hotline at (714) 834-2000 can also answer questions about vaccinations and Othena in Vietnamese, Spanish and English. If additional support is required, hotline staff can coordinate with Othena representatives.

I registered in Othena and then received a vaccination from a provider other than the County. How can I deactivate my Othena account?
To deactivate your Othena account, you can send a request to support@compositeapps.net and Othena can deactivate the account.
