COVID-19 Vaccine:

Whitman-Walker Health encourages you to get your COVID-19 vaccine or booster as soon as possible. New cases of COVID-19 are increasing rapidly. Whitman-Walker has the COVID-19 vaccine available. Schedule a COVID-19 vaccine booster and/or flu vaccine with us. Call Whitman-Walker Health at 202.207.2480 or text 202.978.6123 to schedule a vaccine appointment.

The CDC now recommends booster shots for eligible groups and recommends mRNA vaccines (the U.S. approved Pfizer-BioNTech and Moderna vaccines) over the Johnson & Johnson vaccine. Receiving any of the approved vaccines offers more protection against severe symptoms from COVID-19 than not getting a vaccine at all. The CDC notes that individuals who are unable or unwilling to receive an mRNA vaccine will continue to have access to Johnson & Johnson’s COVID-19 vaccine.

Booster Shot Eligibility:

Anyone who is 16 and older who got their second Pfizer-BioNTech shot at least 5 months ago is eligible for a booster shot in the U.S.
Anyone who is 16 and older who got their second Moderna shot at least 5 months ago is eligible for a booster shot in the U.S.
Anyone who received a Johnson & Johnson shot at least two months ago is eligible for a a booster shot in the U.S.
According to the CDC, If you are 18 years or older you may choose which COVID-19 vaccine you receive as a booster shot. Some people may prefer the vaccine type that they originally received, and others may prefer to get a different booster. CDC’s recommendations now allow for this type of mix and match dosing for booster shots.
The CDC now recommends boosters for folks ages 16-17 years old. Only the Pfizer vaccine is currently authorized for folks under 18.
CDC recommends that moderately or severely immunocompromised 5–11-year-olds receive an additional primary dose of vaccine 28 days after their second shot. At this time, only the Pfizer-BioNTech COVID-19 vaccine is authorized and recommended for children aged 5-11.
Teens 12-17 years old may get a Pfizer-BioNTech COVID-19 vaccine booster.

Talk to Your Provider: If you are currently getting chemotherapy for cancer, are a transplant patient, are currently pregnant or breastfeeding, or have a history of severe allergies, we encourage you to speak to your provider before getting vaccinated. According to the CDC, COVID-19 vaccination is recommended for people who are trying to get pregnant now or might become pregnant in the future, as well as their partners. If you get pregnant after receiving your first shot of a COVID-19 vaccine that requires two doses (Pfizer-BioNTech COVID-19 vaccine or Moderna COVID-19 vaccine), you should get your second shot to get as much protection as possible.

Questions We Have Heard from Community:

1. Is the COVID-19 vaccine safe?

There is strong evidence that the vaccine is both safe and effective. The Johnson & Johnson, Pfizer and Moderna COVID-19 vaccines were approved by the US Food & Drug Administration (FDA) for emergency use in the United States because the data have shown that the vaccine is safe and effective.

The CDC now recommends booster shots for eligible groups and recommends mRNA vaccines (the U.S. approved Pfizer-BioNTech and Moderna vaccines) over the Johnson & Johnson vaccine. Receiving any of the approved vaccines offers more protection against severe symptoms from COVID-19 than not getting a vaccine at all. The CDC notes that individuals who are unable or unwilling to receive an mRNA vaccine will continue to have access to Johnson & Johnson’s COVID-19 vaccine.

There were more than 40,000 patients enrolled in the Johnson & Johnson vaccine study, approximately 40,000 patients enrolled in the Pfizer vaccine study, and approximately 30,000 patients enrolled in the Moderna vaccine study. The FDA will be reviewing other COVID-19 vaccines for approval, and all vaccines will go through the same rigorous FDA approval process. The FDA approval process is considered to be the most rigorous in the world.

2. Who was included in the clinical trials?

People of all races, ethnicities, and genders were included in the studies.

People aged 5 and older were included in the Pfizer vaccine study. People aged 18 and over were included in the Moderna and Johnson & Johnson vaccine studies.

3. I am Black. Will the vaccine be harmful to me?

The data have shown the vaccine is safe and effective for all races and ethnicities, including Black and African American people. Black and African American people took part in the COVID-19 vaccine trials. The results indicate that the vaccine causes only mild side effects in the majority of participants, regardless of race. The results also indicate that the vaccine is equally effective in all participants, regardless of race.

4. I am a person of color. How can I trust that the vaccine is safe?

The data have shown the vaccine is safe and effective for all races and ethnicities. These COVID-19 vaccine trials included a group of more than 110,000 participants, from different backgrounds and ethnicities, including people who identify as Black and African American. We understand that generations of experimentation on Black people and persons of color globally, has left many people untrusting of the medical field and wary of taking a vaccine. Science and ethics have continued to evolve together. Today, research is conducted with community advisory boards to ensure a quality, thoughtful and ethical study.

5. Is an emergency use authorization the same as a standard authorization?

No, it is not the same. But it is still a very high standard. There is strong evidence that the vaccine is both safe and effective.

6. Were the studies rushed in order to get the vaccines distributed quickly? How did this vaccine get approved so quickly compared to other vaccines?

Efforts to develop the COVID-19 vaccines have not skipped steps. Neither scientific standards nor safety standards were lessened, or decreased, in any way.

One of the reasons that the trials were completed quickly is because of the high rates of COVID-19 infection in the US and around the world. This means that study participants were quickly and frequently exposed to people who were infected over the course of their everyday lives. This is not usually the situation when vaccines for other illnesses are tested—so it takes more time for those studies to determine effectiveness.

What is still being studied is how long the immunity will last. This is something that would normally be determined through a standard authorization process where the patients were followed over an extended period of time. That part of the trial is still going on. The emergency authorization process was created in order to quickly distribute vaccines once their safety and effectiveness have been established. It is not uncommon for vaccines to require booster doses in order to shore up, or support, the immune response. As they follow the study patients over a longer period, they may discover that patients need booster doses or they may not.

7. Can patients with HIV get the vaccine?

Yes. Patients with HIV have been approved to receive the Moderna and Pfizer vaccine.

8. What will the COVID-19 vaccine cost?

The vaccine will be free.

9. I’ve had COVID-19 before. Will I still be able to get vaccinated?

Yes. The CDC is recommending that people with prior COVID-19 infection do get vaccinated. Health officials say that the vaccine may provide a more “robust” immune response than getting the illness itself. Also, immunity to COVID-19 can wane. So, even if someone did test positive for COVID-19 in the past, a vaccine is still important. But if you are actively sick, you should wait to get the vaccine.

10. How long does the COVID-19 vaccine last once administered?

According to the CDC, it’s not yet known how long COVID-19 vaccine protection lasts. Recent studies show that protection against the virus may decrease over time. This reduction in protection has led the CDC to recommend that people get a booster shot at least 2, 5 or 6 months after completing their initial vaccination series depending on what vaccine they got. Learn more about how the CDC monitors for vaccine effectiveness here.

11. Can my minor child get the vaccine?

The Pfizer vaccine is approved for use for ages 5 years and older. The Moderna vaccine is for ages 18 and older.

12. Are there any side effects to the COVID-19 vaccine?

While there is no evidence of long-term side effects, notable short-term side effects include fatigue, headache and possible low-grade fever. Most people say these symptoms last about a day. These symptoms are a sign that your body is building an immune response—in other words, that the vaccine is working.

13. Does the vaccine work/is it effective?

Primary efficacy analysis of the Pfizer and Moderna vaccines showed them to be 95 and 94 percent effective, respectively. The Johnson & Johnson vaccine has 72 percent efficacy. That is good efficacy. (For reference, the seasonal flu vaccine has an efficacy rate of 50 percent among some populations.) But that doesn’t mean you should throw away your masks or plan a large gathering just yet. COVID-19 vaccines are effective at preventing COVID-19 disease, especially severe illness and death. COVID-19 vaccines reduce the risk of people spreading COVID-19.

With more variants of COVID-19 and the effectiveness of the vaccine decreasing over time, the CDC now recommends booster shots for eligible groups and recommends mRNA vaccines (the U.S. approved Pfizer-BioNTech and Moderna vaccines) over the Johnson & Johnson vaccine. Receiving any of the approved vaccines offers more protection against severe symptoms from COVID-19 than not getting a vaccine at all. The CDC notes that individuals who are unable or unwilling to receive an mRNA vaccine will continue to have access to Johnson & Johnson’s COVID-19 vaccine.

14. Do I still have to wear a mask and follow the current COVID-19 preventative guidelines if I get the COVID-19 vaccine?

Once you are fully vaccinated (either 2 weeks after your 2-dose or 1-dose shot), the CDC has shared guidance on when fully vaccinated people should wear mask and when they don’t have to wear a mask. See more information here. If you are not fully vaccinated, the CDC recommends that during the pandemic people wear a mask and practice physical distancing when in contact with others, including others from your household, when in healthcare settings, and when receiving any vaccine, including a COVID-19 vaccine.

15. There are several vaccines on the market. Are they all equally effective? Can I choose which one I want?

The CDC now recommends booster shots for eligible groups and recommends mRNA vaccines (the U.S. approved Pfizer-BioNTech and Moderna vaccines) over the Johnson & Johnson vaccine. Receiving any of the approved vaccines offers more protection against severe symptoms from COVID-19 than not getting a vaccine at all. The CDC notes that individuals who are unable or unwilling to receive an mRNA vaccine will continue to have access to Johnson & Johnson’s COVID-19 vaccine.

16. How does the vaccine work?

All of the vaccine platforms work essentially the same way. Both the Pfizer and Moderna vaccines make use of something called mRNA technology. It works by injecting people with a tiny fat bubble, or lipid, containing a part of the “blueprint” material for the virus.

That blueprint gets into the muscle and eventually white blood cells. Then, the cells make a harmless piece of “spike protein,” which is the part on the outer surface of the COVID-19 virus that binds to and infects your cells.

The Johnson & Johnson vaccine is a recombinant vector vaccine that uses a harmless adenovirus to make copies of the COVID-19 spike protein.

Your body then recognizes that the protein doesn’t belong there and builds an immune response, which is why you may feel some tenderness, headache or experience a low-grade fever after getting the vaccine.

The other vaccines in development stages work essentially the same way, though they’ll use different methods than the mRNA technology to show your body that harmless spike protein and prompt it to build an immune response to COVID-19.

17. I am due for other vaccines as well. Can I get the COVID-19 vaccine too?

Yes. At this time, CDC says that the COVID-19 vaccine may be administered with other vaccines without regard to timing.

18. Does the vaccine work as post-exposure prophylaxis?

The CDC does not recommend using the COVID-19 vaccine as post-exposure prophylaxis. Individuals with an exposure to COVID-19 should wait until their quarantine period has ended before being vaccinated.

19. Does substance use affect the COVID-19 vaccine?

If a person participates in ongoing or irregular substance use (such as use of meth, cocaine, heroin, marijuana, etc.), they should still consider getting the COVID-19 vaccine. There are no contraindications, or reasons to not be vaccinated, due to use of substances.

20. What happens when I am fully vaccinated?

The CDC shared recommendations on how to safely gather for folks who have been fully vaccinated. Learn more here.

21. Can I get a booster dose that differs from my original vaccine? Can I mix and match my booster vaccine with my first vaccine?

Yes. According to the CDC, you may choose which COVID-19 vaccine you receive as a booster shot. Some people may have a preference for the vaccine type that they originally received, and others may prefer to get a different booster. The CDC’s recommendations now allow for this type of mix and match dosing for booster shots.

22. What is the difference between a booster dose and an additional dose of an mRNA vaccine?

There are two distinct potential uses for an “extra dose” of COVID-19 vaccine: a booster dose and an additional dose. A booster dose is a third dose of the vaccine after the initial good immune response has started to decrease in effectiveness, while an additional dose is given as part of the initial vaccine series to those individuals who are unlikely to mount a good immune response to the initial vaccine series because they are moderately to severely immunocompromised.

23. Do booster doses change the definition of “fully vaccinated” for those eligible for booster shots?

No. People are still considered fully vaccinated two weeks after their second dose in a 2-shot series, such as the Pfizer-BioNTech or Moderna vaccines, or two weeks after a single-dose vaccine, such as the Johnson & Johnson vaccine. This definition applies to all people, including those who receive an additional dose as recommended for moderate to severely immunocompromised people and those who receive a booster shot.

24. Who is most at risk of hospitalization and death from COVID?

Nearly all the cases of severe disease, hospitalization, and death from COVID-19 continue to occur among the unvaccinated. The CDC emphasizes that the populations most vulnerable to COVID-19 are those who are unvaccinated, and the nation’s priority should remain getting everyone fully vaccinated.
