Frequently asked questions about COVID-19 vaccine
April 28, 2023: An updated (bivalent) vaccine is recommended for everyone ages 6 months and older.
The updated (bivalent) vaccines target Omicron variants that continue to circulate in our communities. The vaccine also targets the original strain of the COVID virus. People who stay up to date with all recommended vaccine doses have the best protection against severe COVID-19.
CDC COVID-19 vaccine recommendations as of April 19, 2023:
Everyone aged 6 years and older should get 1 updated Pfizer or Moderna COVID-19 vaccine to be considered up to date.
Some people may get additional COVID-19 boosters:
- People aged 65 years and older may get 1 additional updated COVID-19 booster dose 4 or more months after the 1st updated COVID-19 vaccine.
- People who are moderately or severely immunocompromised may get 1 additional updated COVID-19 booster dose 2 or more months after the 1st updated COVID-19 vaccine.
Children aged 6 months to 5 years may need multiple doses of COVID-19 vaccine to be up to date, including at least 1 updated dose of Pfizer or Moderna. It depends on the number of doses they’ve previously received and their age.
Please check with your healthcare provider if you have questions about how many doses you need.

Questions we have commonly heard from people in King County
COVID-19 vaccines are being distributed to hospitals, pharmacies, community health centers and other providers. Learn more about where to get vaccinated in King County.
- No, the COVID-19 vaccine can't give you magnetic properties, including at the site of vaccination (your arm).
- There is nothing in the vaccines that can produce an electromagnetic field. All COVID-19 vaccines don't have any metals such as iron, nickel, cobalt, lithium, and rare earth alloys. They also don't have any manufactured products such as microelectronics, electrodes, carbon nanotubes, or nanowire semiconductors.
- See the full ingredient lists for the COVID-19 vaccines below in the How COVID-19 vaccine works section.
The American College of Obstetricians and Gynecologists and the CDC recommend getting a COVID-19 vaccine if you are pregnant, trying to get pregnant, or breastfeeding. Getting a vaccine could help both you and your baby.
- Pregnant people have a higher risk of severe illness from COVID-19.
- The vaccines are very effective at preventing COVID-19 infection, severe illness, and death, and protection may be passed on to your baby as it develops.
- A growing amount of data confirms that COVID-19 vaccines are safe during pregnancy. There is no evidence to show that getting a vaccine increase the risk of miscarriage. If you have questions, talk to your doctor.
Yes, you should be vaccinated regardless of whether you already had COVID-19. Vaccinations offer a more predictable protection, and they will likely last longer.
If you have already had COVID-19, you will likely have some level of natural immunity, but this can vary greatly from person to person. We also don't know how long that natural protection lasts and whether it will protect from other variants. That means that you could eventually be reinfected with the virus or with a different variant.
Getting vaccinated after infection is safe and will offer you the best overall protection against future COVID-19 infections.
- Look up your vaccination from WA state's "My Immunization Registry" (MyIR). If you have registered, log in to MyIR to look up your vaccination record, and then print or take a screenshot or photo of the information. If you do not have an account, you can sign up for MyIR any time.
- Use the mobile version of WA state's immunization registry, MyIRmobile to get a vaccination certificate. MyIRmobile matches records based on name, birthday, phone, and email. If any of these fields are missing or incorrect you will be unable to match your record. For matching issues, you can use the chat feature in MyIR Mobile or call 833-VAX-HELP.
- If you received your vaccine at your health care provider, the provider's office should be able to give you a copy of your record.
- You may go back to the site you were vaccinated and ask a clinic supervisor for a new card. They may be able to look you up and create a new card.
Your child may have a sore arm, feel achy and have a fever from the COVID-19 vaccine, similar to side effects from other vaccines for children. These side effects are temporary and usually go away in 1-2 days.
Cases of myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the outer lining of the heart) have been reported after Pfizer COVID-19 vaccination of older youth, ages 12–17 years. These reactions are rare and mostly in young males. In general, people who developed these conditions were able to quickly recover after treatment.
In the clinical vaccine trial in children aged 5-11, there were no cases of myocarditis in the three-month follow-up period after vaccination. The clinical trial is ongoing and the CDC and FDA have systems in place to continue to monitor and detect possible reactions or other uncommon side effects.
No. There is no evidence that any vaccines, including COVID-19 vaccines, can cause female or male fertility problems. Millions of women have become pregnant after getting the COVID-19 vaccine. Unvaccinated women have a higher risk of death or death of their baby than women who were vaccinated against COVID-19.
