En español | Which vaccines are available and who can get them?
- Pfizer & Moderna: Authorized for people age 6 months and older. Both Pfizer and Moderna use mRNA technology, which prompts the body to make its own version of COVID-19’s spike protein, a key part of the virus. Both require two shots spaced apart for full primary vaccination, except for Pfizer recipients ages 6 months to 4 years, who are given three separate doses.
- Novavax: Authorized for people age 12 and older. Novavax uses a more traditional vaccine technology, directly delivering a lab-made version of the COVID spike protein upon injection. Requires two shots spaced apart for full primary vaccination.
- Johnson & Johnson (J&J): Authorized for people 18 and older who only have access to the J&J vaccine, or who cannot receive a Pfizer or Moderna vaccine for medical reasons. The U.S. Food and Drug Administration (FDA) updated its J&J guidance due to a rare but serious blood clotting disorder associated with the one-shot vaccine.
Which boosters are available and who can get them?
The Centers for Disease Control and Prevention (CDC) recommends getting an Omicron-specific booster, which targets the original strain of the coronavirus as well as the variants that are currently circulating and are expected to continue circulating into the fall (BA.4 and BA.5). The original vaccines, called monovalent vaccines, will no longer be available as booster doses for people 5 years of age and older.
- Pfizer boosters: People ages 5 and older should get Pfizer’s omicron-specific booster at least two months after receiving a primary series or booster, according to the CDC.
- Moderna boosters: The CDC recommends people ages 6 and older get Moderna’s omicron-specific booster at least two months after receiving a primary series or booster.
- Novavax boosters: Adults age 18 or older are authorized to get this booster at least six months after receiving their primary series if they have not yet gotten a COVID-19 booster, the CDC says. Novavax’s monovalent booster is available for adults who cannot or will not get an mRNA vaccine or the Omicron-specific booster.
- Immunocompromised people: Third doses of Pfizer and Moderna, distinct from boosters, are recommended for specific immunocompromised people 12 and older. People in this age group who are immunocompromised are eligible to get an omicron-specific Pfizer bivalent booster at least two months after their primary vaccine series and boosters, regardless of how many they’ve previously received. For people 18 and older with the same health conditions, an omicron-specific Moderna bivalent booster is recommended at least two months after their primary vaccinations and boosters, no matter how many they’ve received previously. For immunocompromised children 11 and younger, the CDC has specific recommendations.
Can I mix and match boosters?
It’s safe and effective to choose which vaccine you receive as a booster, either Pfizer or Moderna, regardless of which initial vaccines you received.
Note that the Novavax booster can only be used as a first booster shot; if you’ve already gotten one or several COVID-19 boosters, you cannot receive a Novavax booster. Health officials have discouraged people from receiving an initial J&J vaccine or booster due to a rare but serious blood clotting disorder.
Where can I get a vaccine or a booster?
- Pharmacies, health departments, clinics and other locations: Shots and boosters are being administered at retail pharmacies and facilities affiliated with the Maryland Department of Health, certain federally qualified health centers, local clinics and other locations, such as doctor’s offices.
Use the federal government’s vaccine website Vaccines.gov to search for vaccination sites by zip code. Get the same information by texting your zip code to 438829 or by calling 800-232-0233. You can also check with your primary physician’s office to see if COVID-19 vaccinations are being offered. If you are a veteran, the Department of Veterans Affairs is offering COVID-19 vaccinations at VA facilities. Sign up online or call 800-827-1000 to make an appointment.
What should I bring to my vaccination or booster appointment?
Some vaccination sites ask for proof of identity or eligibility. Bring a driver’s license or other state-issued ID that shows your name, age and state residency, along with your health insurance card, if you have one. You won’t be charged for the initial vaccine series, or a booster shot, but the vaccine provider may bill your insurer a fee for administering the vaccine. After your first shot, bring your vaccine card for subsequent shots.
How are vaccinations working in nursing homes and long-term care facilities?Most residents and staff of Maryland's long-term care facilities were offered first and second doses through a federal program that provided free on-site vaccinations in late 2020 and early 2021. The program has ended, but the federal government continues to allocate COVID-19 vaccines and boosters to pharmacies that are partnered with long-term care facilities to provide vaccinations, mainly on-site. Facilities that don’t have a pharmacy partner are encouraged to work with local or state health departments — or the federal government, if need be — to provide vaccinations.
Do I have to pay for the vaccination?You should not have any out-of-pocket costs for getting the vaccine. AARP fought to make sure the federal government is covering the cost of the vaccine. The federal government is buying the vaccine and getting it to providers for free.
There are reports of scammers purporting to offer COVID vaccines and treatments and trying to charge for them. AARP’s Fraud Watch Network is tracking the latest scams.
What should I do with my vaccine card?You should get a small white card at your vaccination appointment with your name, birth date, name of the vaccine you received and the date it was administered. If you receive the Pfizer, Moderna or Novavax vaccine, bring your card when you get your second shot.
You may need your vaccine card to schedule a third vaccine dose, for certain immunocompromised people, or a booster shot. You may also need it for certain kinds of travel or other activities and may want to take a photo of it with your smartphone for your own records. But experts warn that posting a photo of your card to social media could make you vulnerable to identity theft.
If you’ve lost your vaccine card, call the site where you were vaccinated to request a new one or a copy of your vaccination record. You can also contact Maryland's health department to request a replacement card or a copy of your record.
How protected am I post-vaccination?
All vaccines reduce the risk of COVID-19 infections and are highly effective at preventing severe illness and death from the disease. But no vaccine is 100 percent effective and infections can still occur post-vaccination.
