The FDA has approved newly formulated boosters for the mRNA COVID-19 vaccines from Pfizer and Moderna. These new shots give vaccine recipients — including those who are immunocompromised — extra protection against variants of SARS-CoV-2, the virus that causes COVID-19. These variants spread more quickly from person to person and can be resistant to the original vaccines. The spread of the omicron variants has led to a spike in breakthrough cases — people become infected with the coronavirus despite being fully vaccinated.
Following the FDA’s approval, the Centers for Disease Control and Prevention (CDC) recommended the updated boosters. “The updated COVID-19 boosters are formulated to better protect against the most recently circulating COVID-19 variant,” said Dr. Rochelle Walensky, director of the CDC, in a statement. “They can help restore protection that has waned since previous vaccination and were designed to provide broader protection against newer variants.”
On its website, The Arthritis Foundation “strongly advocates for vaccination and encourages everyone to seek out the recommended number of primary vaccine doses and booster shots.”
The nonprofit advises individuals with arthritis to talk to their doctors about when the best time might be to get booster shots to protect against COVID-19.
The updated COVID-19 boosters are available now throughout the U.S. Vaccines.gov offers a tool to find nearby locations to receive the booster.
People who’ve followed the recommended COVID-19 vaccine schedule are no strangers to booster shots. Their purpose is to keep your immune system primed with the necessary antibodies to fight the coronavirus. These antibodies naturally lessen over time.
The first set of FDA-authorized mRNA vaccines contained a blueprint of the spike protein found on the original strain of the coronavirus. Using the blueprint in the vaccine, a person’s immune system learns what the coronavirus looks like and how to fight it. The original mRNA vaccines are called monovalent vaccines because they contained blueprints for just one virus component (part).
The new versions are called bivalent vaccines because they contain blueprints for two different spike protein components: one from the original version of the coronavirus and a new one found on the BA.4 and BA.5 omicron subvariants. These are the subvariants that have proven resistant to the original vaccines. By getting an updated bivalent booster, your immune system will be able to recognize and fight both the older and newer, more prevalent subvariants.
Bivalent booster guidance from the FDA and CDC varies depending on a person’s age, vaccination status, and whether or not they’re moderately or severely immunocompromised — that is, whether they have a weakened immune system.
Per the CDC and FDA, people 6 and up who are fully vaccinated and who aren’t immunocompromised are eligible for a single booster dose of the bivalent Moderna COVID-19 vaccine. People 5 and up who are fully vaccinated and who aren’t immunocompromised are eligible for a single booster dose of the bivalent Pfizer COVID-19 vaccine.
Before getting an updated booster, people should wait at least two months after completing their initial vaccine series or receiving a booster dose of a monovalent COVID-19 vaccine.
The booster you receive doesn’t need to be from the same manufacturer as your primary series or previous boosters.
Public health experts advise people who’ve recently contracted COVID-19 to wait until they are fully recovered from the acute illness before getting an updated booster. The CDC has said that getting a booster between the time you first recover from your infection up to three months later may boost your immune response.
“If you’ve had a recent infection or were recently vaccinated, it’s reasonable to wait a few months,” said White House COVID-19 Response Coordinator Dr. Ashish Jha during a Sept. 6 press conference.
The agency offers a COVID-19 booster tool to help people determine if and when they can get a booster.
People who are moderately or severely immunocompromised due to other health conditions face a higher risk of severe illness or death from COVID-19, according to the CDC. Rheumatoid arthritis (RA) is not listed on the CDC’s list of underlying conditions that put people at higher risk for severe illness. The list includes such conditions as HIV, a history of smoking, cancer, and heart problems.
However, some treatments for RA may lower your immune system, so it’s always wise to check with your doctor to see if your medication and dose qualify you as having a suppressed immune system.
Some members of myRAteam have shared their experiences with vaccination against COVID-19. “I’ve now had four vaccines for COVID-19,” one member wrote. Another said, “Got my fifth shot!”
According to the FDA, bivalent COVID-19 vaccines — that is, vaccines containing the old and new spike proteins — are safe and effective, based on results from human trials. Notably, those tests used a bivalent vaccine containing an earlier omicron subvariant called omicron BA.1. Currently, the newly approved vaccines containing the omicron BA.4 and BA.5 subvariants have been tested only on animals.
Nevertheless, the FDA and CDC believe the positive test results of the older bivalent vaccine are relevant to the newly approved vaccines, as they were all developed using the same manufacturing process.
It’s not unusual for the FDA to approve an updated vaccine that hasn’t undergone tests on humans. The most common example is the flu vaccine, which is updated annually based on what scientists predict will be the most common version of the flu virus that year. Those flu shots are generally updated using the same manufacturing process that’s consistently yielded safe, effective vaccines.
When it comes to people with RA, the COVID-19 vaccine appears to be safe, without significant side effects outside of what the general population has reported.
A 2022 study shared the outcomes of 1,367 people with rheumatic diseases who received the COVID-19 vaccine. The study authors noted that “COVID-19 vaccination is associated with no increased risk of side effects in any particular disease or drug therapy, therefore vaccination should be encouraged in patients with rheumatic disease.”
Potential side effects, both common and rare but serious, are similar to those of previous versions of the vaccine. Among individuals with rheumatic diseases, common side effects included pain and swelling at the site of the injection, fever, headache, and fatigue. These side effects are similar to those of a mild flu and may affect your quality of life. It may be helpful to schedule your vaccination for a day when you’ll be able to rest afterward.
Side effects generally fade within a few days. Applying a cool, clean washcloth to the injection site can reduce discomfort. It may also help to move your arm around to relax your muscles and lessen soreness. Try to drink plenty of fluids after the vaccination.
Contact your health care provider if these side effects last longer than a few days, if they seem especially intense or worrisome, or if your injection side is still red and irritated 24 hours after your shot.
U.S. health officials predict people who receive an updated COVID-19 booster won’t need another booster for a year. According to Dr. Jha, people may be able to receive a single booster each year that’s been updated to combat the most prevalent coronavirus variants. “Barring any new variant curveballs, for a large majority of Americans, we are moving to a point where a single, annual COVID shot should provide a high degree of protection against serious illness all year,” he said during a press briefing.
Health experts generally agree that severe side effects from a COVID-19 vaccine are extremely rare. “The benefits of COVID-19 vaccination outweigh the known and potential risks,” notes the CDC.
People who aren’t fully vaccinated face a higher risk of developing a severe COVID-19 infection, requiring hospitalization, or dying from the disease.
If you’re living with RA and you have questions or concerns about getting the updated booster, speak with your rheumatologist or another health care provider.
On myRAteam, the online social network for people with rheumatoid arthritis and their loved ones, more than 196,000 members come together to ask questions, give advice, and share their stories with others who understand life with RA.
