Your Resource for Vaccination Information

Last updated: 4/16/2021

Together, we can keep our community healthy. The COVID-19 vaccine is safe, effective, and the best way to end the spread.

We understand that some people in the community are worried about the safety of the vaccine, or might be concerned about side effects. We have included some COVID-19 vaccine FAQs and resources from trusted organizations on this page. This information will help explain why vaccination is such an important tool to keep you and your community safe and end the spread of this deadly virus.

Huntington operates a closed clinic where we vaccinate at the direction of Pasadena Public Health Department.

All LA County residents 16 years and older are currently eligible to receive the vaccine.

Vaccination Registration Options:

There are now many options for vaccine registration in Los Angeles County. We will continue to update this list daily and provide any updates we receive from the city and the county.

Los Angeles County

  • Los Angeles County residents can go online to schedule their appointments, or call (833) 540-0473 between 8 a.m. and 8:30 p.m. for assistance with reservations.
  • This phone number can also be used to arrange for transportation to a vaccination site. Additionally, eligible individuals whom are homebound can also call (833) 540-0473 to get vaccinated in-home.
  • The California Department of Public Health is encouraging residents to visit the site to determine if they are eligible for the vaccine and schedule appointments.


City of Pasadena is also providing vaccinations to eligible individuals who reside in the city – you must have a Pasadena residential address. Seniors in Pasadena can fill out this form if they would like to note their interest in getting the vaccine, or call  (626) 744-7311. We have more details on the Pasadena registration option here.

Pharmacies in Your Area

The Pasadena Public Health website shares these additional pharmacy locations that are now registering limited COVID-19 vaccine appointments.

Los Angeles is the most populous county in the entire nation, with more than 10 million residents. The vaccination process is dependent on supply of vaccine and the availability of individuals to administer it. We ask you to remain hopeful and patient as this process unfolds; everyone who wants a vaccine will ultimately be offered one. 

As for what we can all do until everyone who wants a vaccine has been offered one: we must continue to follow the guidelines related to masking, distancing and not gathering with those outside of our household. Now is the time for us to double down on our efforts to keep ourselves, our families and our community safe.

COVID-19 Vaccine FAQs

COVID-19 Vaccine Basics

Q. What is the COVID-19 vaccine?

A. The COVID-19 vaccine is a shot that teaches our immune system how to recognize and fight the virus that causes COVID-19. It’s the same idea behind the flu shot that Americans have been getting since the 1940s. The Food and Drug Administration (FDA) authorized the use of COVID-19 vaccines to help stop the spread of the pandemic.

Q. Why should I get the vaccine?

A. You should get vaccinated when it is your turn because it will help keep you safe and help us stop the spread. COVID-19 is dangerous – it can be fatal or have long-lasting impacts, even in young, healthy people. The risks from getting sick with COVID-19 are much larger than any possible risk from getting vaccinated. While getting the vaccine may not prevent you from getting COVID-19, it does stop you from getting sick and developing symptoms.

COVID-19 variants: The COVID-19 variants circulating now are very contagious, an important reason for everyone to get vaccinated. In addition, vaccination can prevent more variants from being created.

Q. Is the COVID-19 vaccine safe?

A. Yes. There have been no reported serious safety concerns from COVID-19 vaccines. The CDC and the FDA continue to monitor individuals who have received the vaccine to ensure there’s no evidence of even rare safety issues. Although the COVID-19 vaccine is new, the science behind creating a vaccine has been around for a long time and is scientifically proven to be safe and effective.

Millions of people have safely received a COVID-19 vaccine, and careful monitoring efforts have supported the science demonstrating vaccine safety.

Q. Does the COVID-19 vaccine work?

A. Yes, we know that all the COVID-19 vaccines currently available in the United States have been shown to be highly effective at preventing COVID-19. You can read about the different vaccines in use on the CDC website (see our Resources section).

Q. I’ve heard a lot of different things about the vaccine, how do I know what to believe?

A. There is a lot of information about vaccines in the news right now, and some of it is not based in science. We encourage you to read the articles included in our Resources section at the end of this brochure from the Centers for Disease Control (CDC) and Food and Drug Administration (FDA) and other trusted institutions.

What to Expect from the COVID-19 Vaccine

Q. Are there any side effects from the COVID-19 vaccine?

A. Yes, some people do experience side effects from the COVID-19 vaccine. Most side effects reported were mild to moderate in severity and resolved within 24 hours. Side effects included pain at the injection site, fatigue, headache, muscle pain, chills, joint pain, and fever. More people experienced these side effects after the second dose than after the first dose.

Q. Can I get COVID-19 from the vaccine?

A. No. It is not possible to get COVID-19 from vaccines. Current vaccines use only genetic material from the virus while other vaccines being studied use inactivated virus. None of these can cause COVID-19.

Q. How long will it take for the vaccine to begin protecting me?

A. It normally takes about two to three weeks to start getting some protection, and about six weeks for full protection. Important: even after you have received both doses of the current vaccines, you must give your body time (2-6 weeks) to have the full benefit of vaccination.

Q. Do I need to get a second vaccinate shot, or booster, if I’ve already the first shot?

A. Yes. In order to be effective, the current vaccines require two doses. Please be careful about scheduling your second dose on time, even if the system for doing so is hard to use. The second dose is critical for your protection.

After you have received both doses, you must give your body time (2-6 weeks) to have the full benefit of vaccination.

Q. Will I have to continue wearing a mask after I get the vaccine?

A. Yes. We should all continue wearing face masks, washing our hands, and social distancing until enough vaccine is in the community, until we know how long a vaccine will protect us, and until we have slowed the spread.

Continuing these safe practices after vaccination is important because we don’t yet know whether getting a COVID-19 vaccine will prevent you from spreading the virus to other people, even if you don’t get sick yourself.

Q. If I have had COVID-19 should I get the vaccine?

A. Yes. Even if you suspect or know that you had COVID-19, it is still recommended that you et vaccinated when you are eligible.

People who test positive for COVID-19 may have partial protection, be we don’t know how long that protection lasts or how effective it is. If you’ve had a positive COVID-19 test, you should wait 90 days before getting a vaccine.

In addition to protecting yourself, getting vaccinated will help decrease the spread of COVID-19. It can protect people around you, particularly people who are at greater risk for getting very sick from COVID-19 because of their age, health issues or other factors. Vaccination also prevents new variants from developing.

Q. I live in Pasadena – where should I register for the vaccine?

A. Pasadena residents, as well as those working for a healthcare provider in the city, have two options to get a coronavirus vaccine appointment: They can go through the county or the city, unlike most others who can only rely on the county.

Pasadena city officials are asking eligible residents to fill out an online form or call the city’s Citizen Service Center at (626) 744-7311. Either method will get them added to a waitlist, as long as they’re Pasadena residents.

When you believe you are eligible for the vaccine, Pasadena encourages you to first contact your employer or healthcare provider to see if they are administering vaccine. If you cannot get vaccinated that way, please fill out an online form or call the city’s Citizen Service Center at (626) 744-7311.

Pasadena would like to remind residents that they must get their second dose through the same system where they got their first dose. In other words, if you’re a Pasadena resident but you got your first dose through LA County, you will need to get your second dose through the county. That’s because the city allocates its second-round shots based on how many first-round shots it delivered; the county does the same.

Last, Pasadena city officials urge residents not to show up to the city’s vaccination site without an appointment. There will not be any extra doses for people without appointments, and anyone who arrives without an appointment just creates traffic.
