In a world beset by a myriad of respiratory viruses, a new hero emerges: the combination vaccine mRNA-1083. Moderna might just have found a way to consolidate our agony into a single, powerful punch. The company’s latest vaccine—designed to battle both COVID-19 and flu—has shown promising results. Ah, one shot to rule them all, one shot to bind them, one shot to bring them all, and in the immunity bind them.

In a recent late-stage clinical trial, Moderna’s combo vaccine elicited a greater immune response than existing vaccines for both dreaded diseases. It seems like science has finally given us a reason to voluntarily roll up our sleeves again instead of waiting for a friendly nudge—or an outright shove—from public health officials.

The combination vaccine showed a sufficient immune response to three flu strains—H1N1, H3N2, and B/Victoria—and the current headliner of virus reality shows, COVID-19. Of course, they had to make sure it wasn't all wishful thinking, so they gathered about 4,000 adults, split into two age groups: the prime-time crowd aged 50-64 years and the silver surfers who are 65 and older. These brave volunteers participated in randomized trials comparing the combo vaccine against the FDA-approved Fluzone high-dose vaccine and Moderna’s own Spikevax (COVID-19) vaccine.

Despite the fearsome name “Spikevax,” the combo vaccine’s adverse reactions were mostly mild, including the usual suspects: pain at the injection site, fatigue, muscle discomfort, and headaches. No real dragons to slay here—just a minor inconvenience in the grand quest for herd immunity and peace of mind.

Moderna plans to present this phase three study data at an upcoming medical conference and submit it to a peer-reviewed journal, just to make sure that no stone (or band-aid) is left unturned. Their combination vaccine has already received fast-track designation from the FDA, propelling it through the bureaucratic haze at an unprecedented speed. It appears the FDA is as eager as the rest of us to move past the relentless two-shot tango we've been dancing for the last few years.

Moderna isn't stopping there. Their goal is to offer more convenient vaccination options by reducing the burden of respiratory viruses (source). Simplifying the vaccination process might just be the key to achieving higher immunization rates. After all, who wouldn’t prefer a single shot to facing down an artillery of needles?

In fact, Moderna is the first company to announce positive late-stage trial results for a combined COVID-19 and flu vaccine. Public health experts can hardly contain their excitement, as combined vaccines are believed to help improve vaccination rates and better protect public health (source).

There is hope that this single weapon in our arsenal can also combat vaccine fatigue and address the drop in vaccine uptake noticed after the pandemic's initial surge. A “one and done” may be the silver bullet we need to keep our defenses strong without suffering from perpetual needle phobia.

Both age groups in the study—those chasing their mid-century mark and the seasoned aficionados of life—showed statistically significant higher immune responses (source). If nothing else, this shows that it’s never too late—or too early—to beef up your immunity.

So there you have it. In an era of mask debates, social distancing dilemmas, and sanitizer shortages, Moderna has handed us a reason to celebrate. Whether "mRNA-1083" rolls off the tongue as smoothly as "E=mc^2" remains to be seen, but what’s clear is that one shot now has the potential to spare us multiple headaches—both literal and figurative. Here’s to progress, one jab at a time.
