Take the Gloves Off: Rethinking Flu Shot Practices

Every autumn, millions of people line up for their flu jab. The choreography is almost always the same: a technician scrubs their hands, pulls on a pair of nitrile gloves, gives the injection, tosses the gloves into a trash bin, and moves on to the next patient. It’s a routine that feels automatic, but beneath the surface it’s contributing to a quietly growing waste problem.

In the United States, health care accounts for roughly 8.5% of all greenhouse‑gas emissions and about 9% of air pollutants. That’s a hefty footprint for an industry whose mission is to keep people healthy. While big‑ticket items like MRI machines and surgical suites get most of the attention, something as simple as a disposable glove can add up fast.

Consider a midsize hospital with 30,000 staff members required to get a flu shot. If each vaccination follows the usual protocol—hand sanitizer, gloves, injection, glove disposal—the facility will use 60,000 pairs of gloves in a single season. At an average weight of six grams per pair, that’s nearly 90 kilograms of nitrile heading straight to landfill or incinerator.

And the carbon cost is not trivial. Incinerating one pair of non‑sterile gloves releases between 26 and 68 grams of CO₂‑equivalent gases. Multiply that by 60,000, and the hospital adds somewhere between 780 kg and 2,040 kg of greenhouse gases to the atmosphere—roughly the emissions from a passenger car driving 2,000 to 5,200 miles. If the same pattern plays out across the 18 million health‑care workers nationwide, we’re talking about 36 million gloves, over 100 metric tons of solid waste, and up to 1,200 metric tons of CO₂‑equivalent emissions. That’s equivalent to adding 110‑285 extra cars on the road each year, just for gloves.

Beyond the environmental toll, there’s a financial one too. The price of disposable gloves has surged, now hovering around $29 per 1,000 pairs because the raw materials are in short supply. Multiply that by the millions of gloves used for flu shots, and you’re looking at an avoidable expense in the hundreds of thousands of dollars.

So why do we keep using gloves for something as low‑risk as a routine flu jab? The answer lies in a mix of habit, misunderstanding, and over‑cautious policy. The Occupational Safety and Health Administration (OSHA) does not require gloves for vaccine administration unless the provider has an open wound on their hands or anticipates contact with bodily fluids. Hand hygiene—either a quick wash or an alcohol‑based rub—is the key protection step.

In recent years, infection‑prevention experts and sustainability advocates have begun to push back against the “glove‑first” mindset. The U.K.’s “Gloves Off!” campaign showed that hospitals can safely drop routine glove use for “dry” care—tasks that involve only intact skin, such as administering an injection or handling a patient’s belongings. The same logic applies to flu vaccinations: the needle penetrates skin, but the vaccine itself isn’t a bodily fluid, and the syringe tip is sterile.

Adopting a glove‑light approach doesn’t mean compromising safety. It simply means following a two‑step protocol: (1) sanitize hands thoroughly, and (2) wear gloves only if there’s a clear, documented reason—like an open cut or the need to handle a potentially contaminated object. Many health systems have already piloted this change and reported no increase in infection rates, while enjoying a noticeable drop in waste and costs.

Implementing the shift is easier than it sounds. First, update institutional policies to reflect OSHA guidance. Second, train staff on the revised protocol with short, in‑service videos that stress hand hygiene. Third, track glove usage before and after the change to demonstrate the environmental and financial impact. Finally, celebrate the wins—whether that’s a kilogram of waste saved per clinic day or a few hundred dollars kept in the budget.

Small, deliberate changes in everyday practice can ripple into larger climate benefits. When health‑care workers choose to skip an unnecessary glove, they’re not just cutting waste; they’re also sending a message that caring for the planet is part of caring for patients. In a world where climate change is already reshaping disease patterns, that message matters.
