Your Vaccine Appointment

Who can get the vaccine at Roots?

Anyone 12 and up who lives or works in Alameda County can get vaccinated at our Oakland site. A parent or legal guardian must accompany you and sign the consent form if you are under 18. You can sign up on our website by going to and clicking on the black “COVID-19 vaccination” button. The direct link to the registration form is

If you receive a vaccination appointment at our Main Oakland site, here are the details:

Where is it?

9925 International Blvd. Oakland 94603. Go to the parking lot gate and let them know you have a vaccine appointment.

How long will it take?

You will be asked to fill out and sign a consent form prior to being vaccinated. After receiving the vaccine, you will need to stay close by for observation for:

  • 30 minutes if you have a history of severe allergic reaction/anaphylaxis
  • 15 minutes for everyone else.

What do I need to bring? 

If this is your second dose, please bring your vaccination card with you so that we can update it.

After Receiving the Vaccine

How long does it take the vaccine to work?

The vaccine will be at its full effectiveness 2 weeks after your final dose.

Will I have to get vaccinated again in the future?

We are still learning how long the vaccine will last. Experts say that it is effective for at least six months, and it is likely to be effective for longer. For updates on vaccine effectiveness, you can check this CDC webpage for updates.

Will I ever need to take a Covid test again?

Like with most vaccines, it is still possible to get COVID once you are fully vaccinated, although the chances are much smaller. If you get COVID-like symptoms after being vaccinated, especially loss of taste or smell or respiratory symptoms, it is a good idea to get tested again so that you can be aware and take steps to protect others who are not yet vaccinated.

How can I help health officials learn more about COVID and vaccine safety?

After you get the vaccine, please sign up for V-Safe. This is a national program that helps health officials catch any vaccine problems early. You can sign up at: After you register, you will receive brief surveys about how you are feeling for a couple weeks after you receive each dose. You can opt out of the surveys at any time.

Deciding to get the vaccine

Is the vaccine safe?

According to the US Centers for Disease Control & Prevention (CDC), “Millions of people in the United States have received COVID-19 vaccines, and these vaccines have undergone the most intensive safety monitoring in U.S. history. This monitoring includes using both established and new safety monitoring systems to make sure that COVID-19 vaccines are safe. These vaccines cannot give you COVID-19.“

As of 5/26/2021, 131 million people are fully vaccinated against COVID in the United States, which is 40% of the population.

What vaccines are available?

Currently Roots has the Moderna, Pfizer, and Johnson & Johnson vaccines. Below are Emergency Use Authorization (EUA) fact sheets from the FDA that give more detail about these vaccines. They include who should and should not get the vaccine, vaccine ingredients, risks and benefits, and possible side effects. It is recommended that you read or have this document explained to you before you receive the vaccine to make sure that you are making an informed choice:

How do the different  vaccines compare?

*Here is a table comparing different features of the three available vaccines.
Vaccine Moderna Pfizer Johnson & Johnson
Vaccine type mRNA                          mRNA viral vector
Dose schedule 2 doses, 4 weeks apart 2 doses, 3 weeks apart 1 dose
Administration Injection in the deltoid (shoulder) muscle
Age requirement 18+ 12+ 18+
Effective against illness from COVID-19 94% 95% 72%
Effectiveness against hospitalization and death from COVID-19 100%
Effective across gender and race Yes
Common side effects (injection site) Pain, redness, swelling
Common side effects (systemic) Tiredness, Headache, Muscle pain, Chills, Fever, Nausea


How do I decide which vaccine is best for me?

All of the vaccines mentioned above are safe and approved by the FDA for emergency use. The Pfizer vaccine is currently the only one approved for people aged 12 and up. The Johnson & Johnson vaccine requires only one dose, so people who would have difficulty keeping an appointment to receive their second dose on time may prefer the Johnson and Johnson vaccine. Each of the vaccines have different ingredients; if you have allergies to foods or substances, read the ingredient list in the EUA fact sheet to make sure that you are not allergic to any of its ingredients. While the vaccines do show different effectiveness rates against illness (catching COVID) from the different trials, it is important to understand that effectiveness against catching COVID is not as important as effectiveness from causing severe illness, hospitalization, or death. All three available vaccines have been proven 100% effective against severe illness, hospitalization and death from COVID. Therefore, the best choice is any of the vaccines that you are eligible for!

What does the vaccine cost?

Roots currently receives our COVID vaccines from the government for free, so there is no charge for the vaccine itself. If we have your insurance on file, we will bill your insurance for the administrative costs of giving you the vaccine.

Should I get the vaccine if I am pregnant?

Because pregnant women were not included in the clinical trials, it is recommended to discuss the risks and benefits of getting the COVID vaccine with your doctor before making your decision. Read more about the COVID-19 vaccine safety and pregnancy here.

How long do I need to wait to get other (non-COVID) vaccines?

You may not receive any other vaccines for two weeks before and two weeks after the COVID-19 vaccine.

If I got my first dose already, can I get my second dose at Roots?

No, currently there is no mechanism for this. If you got your first dose somewhere else, your second dose was reserved for you there already. Please plan to receive your second dose from the same place you got your first dose.

*Note these are not head-to-head comparisons as trials were done at different times, different parts of the world, and at times when different variants were present.

Are there any dietary considerations for the vaccine? 

At this time there are no special considerations for this. There are no foods or beverages that cause the vaccine to be more or less effective.

Is it safe to get the COVID vaccine even though I take medications?

It is safe to get the vaccine with most common medications. However, if you are taking medications that suppress the immune system, talk to your doctor about when would be best for you to get the vaccine.

Will the COVID test come back positive due to vaccination? 

The viral (PCR) tests that tell whether you have a current infection will not turn positive because of the vaccine. However, the vaccine does cause your body to make antibodies, which is your immune system’s way of being ready to fight the virus if you ever come in contact with it. Therefore, if you take an antibody test it will come back positive.


Do you still have questions about the timing or safety of the vaccine or about whether you should get the vaccine on your specific situation? If so, please reach out to your primary care provider, or request a nurse call-back for questions about the vaccine at
