Recently, the Centers for Disease Control and Prevention (CDC) and the U.S. Food and Drug Administration (FDA) authorized booster shots of all three COVID-19 vaccines. We’ve been getting a lot of questions about children and COVID-19 boosters, so we’ve compiled some answers to your frequently asked questions.
What is a booster shot?
A booster shot refers to an extra dose of a vaccine after the original series of shots has been given. It can be given months or years later. This is common for many vaccines, including influenza (flu), and is now also recommended for the COVID-19 vaccine.
The effectiveness of the COVID-19 vaccine can wane after several months, so the booster shot amplifies your immune response to the COVID-19 virus, increasing your protection against COVID-19 infection, hospitalization and death.
What is the difference between a booster and an additional dose?
A booster shot refers to an extra dose of a vaccine given after the original series of shots. An additional dose is given to people with compromised immune systems, and it helps the build the same level of immunity as people who are not immunocompromised.
Who is eligible for a COVID-19 booster shot?
- Individuals who received the Pfizer vaccine initially, are 16 or 17 years of age and are at least six months out from their second shot are eligible for a Pfizer booster.
- Individuals who received the Pfizer vaccine initially, are 18 years of age or older and are at least six months out from their second shot are eligible for a booster from any manufacturer.
- Individuals who received the Moderna vaccine initially, are 18 years of age and older and are at least six months out from their second shot are eligible for a booster from any manufacturer.
- Individuals who received the Johnson & Johnson vaccine initially, are 18 years of age and are at least two months out from their first shot are eligible for a booster from any manufacturer.
Eligible individuals over 18 years of age may choose which vaccine they receive as a booster dose. Some people may have a preference for 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.
Will younger children eventually need booster shots too?
Researchers are still studying whether or not immunity wears off in children over time. We should know the answer to this question in early 2022.
If my child is eligible, should they get a COVID-19 booster shot?
Yes. While your child’s original vaccine continues to protect them against severe illness and death, it will wear off a bit over time. A booster shot provides extra protection against COVID-19.
Are COVID-19 booster shots different from the original vaccines?
The Pfizer and Johnson & Johnson boosters are the same as their original shots, while the Moderna booster is half of the original dosage.
What side effects can I expect from a COVID booster shot?
You can expect similar side effects to the ones experienced with your initial COVID vaccine. These include soreness in the arm that received the injection, fatigue, chills, fever, headache and muscle and joint pains.
Is it okay to get a booster dose of a different vaccine than the one you originally received?
Yes, boosters can be mixed. If you received Pfizer, Moderna or Johnson & Johnson for your initial vaccine series, you can receive any available COVID-19 booster shot – it does not have to match the brand you received for your first vaccine, though you will get the best protection if you are boosted with a Pfizer or Moderna vaccine. However, if you are 16 or 17 years old and received the Pfizer vaccine you are only eligible for a Pfizer booster.
Will a booster protect me from the omicron coronavirus variant?
Public health and medical professionals worldwide are rushing to learn more about the omicron variant. What we do know is that the booster shot amplifies your immune response to the COVID-19 virus, giving you the best chance of fighting off variants of COVID-19.
