As the weather turns colder, it’s no surprise that more people are catching colds, the flu, COVID-19, and RSV. It’s probably safe to say that sneezing is likely in the forecast for many—vaccines, however, offer a robust defense against these viruses, lessening the severity if you do fall ill.
Winter illnesses are particularly tricky because multiple viruses tend to circulate simultaneously, leading to what experts call a “quad-demic.” This can take a toll on your immune system, increasing the chances of getting sick or even catching more than one bug in a season. Throw in the fact that we spend more time indoors, have busy schedules, and deal with dry air that can irritate our respiratory system, and it’s a recipe for spreading infections.
Vaccines are not just for individual protection; they also help decrease the overall spread of viruses in communities. This is important because fewer infections can lead to less strain on healthcare systems, fewer sick days at work, and fewer disruptions in daily routines. If you do get sick after being vaccinated, studies show that symptoms tend to be milder and recovery happens faster, which can really improve your winter experience.
“Vaccination reduces the risk of severe illness, hospitalization, and complications during a time when healthcare resources are often stretched,” says Dr. Raj Dasgupta, chief medical advisor for Sleepopolis. “For adults over 50, vaccines can be particularly important for maintaining independence, heart health, and lung function throughout the winter.”
So, that brings us to the question: Which vaccine should you prioritize now, and is it too late to get it in February? We consulted four doctors, and they all pointed to one in particular.
Get This Vaccine Before February Ends, Doctors Urge
“The flu vaccine is one that I really hope people still consider before February wraps up,” Dr. Dasgupta points out. “It prepares your immune system to identify the flu strains circulating and lowers the risks of infection, severe illness, and hospitalization.”
Every doctor we spoke with echoed the importance of getting the flu shot in February if you haven’t done so already. “It’s time to get the flu shot,” says Dr. Linda Yancey, an infectious disease specialist. “Cold and flu season lasts until the end of March, and we’re currently seeing a significant number of influenza cases in the U.S.”
But, wasn’t the general idea that you should get the flu shot in the fall? Is it really worth it to get vaccinated this late in the season? It turns out, yes. It’s a case of “two things can be true.”
“The ideal window for getting the flu vaccine is from September to October,” explains Dr. Shasawat Kumar, a board-certified internist. “This timeframe allows immunity to build before the peak flu season, which typically lasts from December to March. However, February is definitely not too late; respiratory illnesses can continue spreading well into the season.”
Dr. Kumar emphasizes that anyone over six months old should consider getting the flu shot.
If you’ve already faced the flu—whether diagnosed or not—getting the vaccine can still offer added protection against different strains of the virus, adds Dr. Mark Loafman, a family physician.
The good news is that flu shots are fairly easy to access in February. “You can find them at various locations, including doctor’s offices, pharmacies, and community health clinics,” Dr. Kumar suggests. “Just check with your physician to find out what’s available nearby.”
Just remember that it takes about two weeks for your body to build immunity after vaccination.
Other Vaccines To Get Before February Ends
In addition to the flu shot, you might want to think about getting other vaccines, including a COVID-19 vaccine or booster. Similar to the flu shot, these are available to individuals aged six months and older.
Dr. Yancey points out that COVID cases are still present and that it’s a good idea to get a booster annually. It might also be time for a TDaP booster to remain protected against tetanus, diphtheria, and pertussis.
“People should receive a TDaP booster every ten years,” she explains. “This vaccine not only offers protection for the individual but also safeguards infants who are at risk for severe outcomes.” That’s why healthcare providers often recommend the TDaP booster during pregnancy, ensuring that the baby gets protection until they are vaccinated themselves.
Additionally, Dr. Yancey advises that those over 65 should also receive the RSV and pneumococcal vaccines, which help prevent pneumonia and can be administered at any time of year.
February sounds like a good time indeed.
Where To Find Reliable Vaccine Advice
With much conflicting information about vaccines, it can be difficult to know whom to trust. “Until recently, we relied on the CDC website for the best scientific data,” explains Dr. Loafman. “The current information is generally reliable, though there are some exceptions. Your doctor can help clarify any confusion.”
Dr. Loafman adds that state health departments and major medical organizations like the American Academy of Pediatrics and the American College of Obstetricians and Gynecologists provide valuable resources that medical professionals turn to for recommendations.
Though the topic of vaccines can feel overwhelming, especially with the varying advice out there, it’s important to prioritize your health and stay informed.
