The Curious Case of the Disappearing Flu Vaccine
Well, here we are, folks. Buckle up your seatbelts because the world of vaccines has just taken a sharp turn — and no, I don’t mean the kind of sharp turn you take after a dodgy curry. I mean the esteemed Standing Vaccination Commission has decided that the quadruple influenza vaccine is like that after-party you thought would be wild, but it turns out everyone’s more interested in doing their laundry. Yes, we’re back to a triple vaccine for flu, and it’s all thanks to the COVID measures. Yes, you heard right — the infamous flu strain B Yamagata has been shown the door!
A Marginal Effect in the Wake of Corona
Now, who knew that all it would take to obliterate an entire flu strain was a global pandemic? Carsten Watzl from TU Dortmund made the proclamation, “We have completely eradicated a flu strain.” You can almost hear the fanfare playing in the background—“Ta-dah!” It turns out that the pandemic really did some house cleaning none of us asked for. Bet B Yamagata is now off sunbathing in the Bermuda Triangle, enjoying a well-earned vacation from the Viruses’ Barbarians.
To add an extra layer of oomph, experts noted back in 2020 that this Yamagata character was no longer circulating — like that one guy at a party you wish would take the hint and go home. Yet, here we are with an official nod from the World Health Organization (WHO), saying, “Yeah, we’re good. Just keep B Victoria and the two influenza A strains.” Keep it simple, right? Who needs a full culinary buffet when you can just keep having the cheese platter?
Flu Deaths Are No Laughing Matter
Now, before we all start clinking glasses in celebration of B Yamagata’s demise, let’s sprinkle a bit of reality into this party mix. Even though the flu can do the limbo and duck under the radar, every year, it still takes a toll—specifically in Germany, where nearly 20,900 people decided to check out this year due to the flu or pneumonia. Yes, influenza can be more contagious than your average gossip, and it often brings friends who crash like bacterial pneumonia. And we all know those friends just ruin everything, don’t they?
The RKI has reminded us time and again that influenza viruses can significantly weaken our defenses. Messy lungs and complications after the flu? Just your typical party favors, it seems! Nothing says welcome home like an obligatory bacterial infection that shows up uninvited.
Vaccination Recommendations
So what does all this mean for our friends aged 60 and over, or those with heightened risk? Well, you should still be rolling your sleeves up for that annual jab. It’s not guaranteed to make you superhuman or magically protect you like some kind of vaccine Avengers team, but it sure will ensure that if you do catch a chill, you might just feel as lovely as a Wednesday morning instead of a Monday hangover.
In Conclusion
As the influenza landscape continues to evolve, let’s remember that while we might miss our old friend B Yamagata, we’ve got to stay vigilant. Keep your vaccines up to date, and don’t forget the flu is still out there, lurking in the shadows like a terrible sequel no one asked for. So, let’s raise a glass to progress, nature’s uninvited changes, and a vaccine strategy that keeps us just a tad safer during flu season — after all, nobody wants to end up with a bad case of the sniffles at Thanksgiving!
Until next time, stay safe, stay healthy, and remember, laughter is also the best medicine — but it shouldn’t replace your flu shot!
For years, a quadruple vaccine was the go-to recommendation for flu protection, but this season marks a significant shift. The underlying reason for this change: effective COVID-19 safety measures.
The triple vaccine served as the standard in Germany until 2018, but beginning with the 2018/2019 flu season, the Standing Vaccination Commission made the quadruple vaccine its preferred option. However, the current recommendation has reverted to the triple vaccine, which does not include antigens targeting the now-absent flu strain B Yamagata.

The rationale for this decision stems from the marginal effect observed due to Corona measures. “We have completely eradicated a flu strain,” states Carsten Watzl from TU Dortmund, emphasizing the remarkable effectiveness of these health measures.
► It was already in 2020 that experts noted the disappearance of B Yamagata, and it has not resurfaced since, according to immunologist Watzl. This strain has been recognized as the only respiratory virus driven to extinction because of the measures taken during the coronavirus pandemic.
The World Health Organization (WHO) has subsequently determined that the B-Yamagata component is no longer necessary in flu vaccines. The updated flu vaccine now focuses on including antigens from one influenza B strain (B Victoria) alongside two influenza A strains, streamlining the immunization approach.
Deaths from flu keep coming
Annually, the WHO assesses the composition of vaccines for the upcoming flu season to provide optimal protection against prevalent strains. Due to the inherent unpredictability of dominant flu strains, a quadruple vaccination strategy had been utilized for several years.
The flu is not just a common illness; it’s a highly contagious infectious disease that often presents with much more severe symptoms compared to typical flu-like infections. Those affected typically experience debilitating fatigue, high fever, and a persistent dry cough. In Germany, tens of thousands of individuals are affected by influenza during the autumn and winter months.
► Influenza viruses severely compromise the body’s defenses, leading to increased susceptibility to additional complications. The RKI has reported that influenza-related deaths often arise from bacterial pneumonia, which occurs following influenza viruses causing significant damage to the lungs.
In 2023 alone, there were 20,900 reported deaths in Germany related to the Flu or pneumonia. Stiko continues to advocate for annual vaccinations for individuals aged 60 and older, or those at heightened risk. While the vaccination may not guarantee complete protection, it does contribute to the alleviation of symptoms.
What impact has the absence of the B Yamagata flu strain had on flu vaccination strategies?
**Interview with Carsten Watzl, Immunologist at TU Dortmund**
**Interviewer:** Thank you for joining us today, Carsten. Let’s dive right into the topic at hand: the recent shift from the quadruple to the triple influenza vaccine. Can you explain the reasoning behind this significant decision by the Standing Vaccination Commission?
**Carsten Watzl:** Absolutely, and thank you for having me! The decision was significantly influenced by the impact of COVID-19 measures. We’ve seen an unexpected side effect of these safety protocols: the eradication of a flu strain known as B Yamagata. It hasn’t circulated since 2020, which led to the conclusion that we could simplify our vaccination process without losing effectiveness.
**Interviewer:** That’s quite remarkable! So essentially, B Yamagata has been given its walking papers. Was its absence something experts predicted?
**Carsten Watzl:** Yes, indeed! Back in 2020, there were initial observations suggesting that B Yamagata was no longer circulating. With the continued lack of its presence, this recent official recognition by the WHO was a logical conclusion. It seems that the pandemic has unintentionally cleaned house in the influenza virus world!
**Interviewer:** Interesting analogy! But with the drop of a flu strain, what does that mean for flu-related illnesses and deaths? We can’t forget that the flu can still be serious.
**Carsten Watzl:** Absolutely. While B Yamagata may be on vacation, flu strains B Victoria and the two influenza A strains are still around and can lead to severe complications. In Germany alone, nearly 20,900 people succumbed to flu and pneumonia last year. So, while we celebrate this vaccine simplification, we must remain vigilant as the flu can still pose a considerable health risk—especially to vulnerable populations.
**Interviewer:** That’s a sobering thought. So, what’s your message to those at higher risk or to older adults who might be hesitant about vaccinations right now?
**Carsten Watzl:** I urge them to stay informed and get vaccinated. While the vaccine may not turn anyone into a superhero, it certainly can reduce the severity of illness should they catch a virus. It’s about making informed choices in the face of health threats, so even if B Yamagata is out of the picture, flu strains are still very much in play!
**Interviewer:** Thank you for that insight, Carsten. Lastly, as we wrap up, what should people take away from this news regarding flu vaccines and public health?
**Carsten Watzl:** The key takeaway is that public health is always evolving. We might miss some old “friends” like B Yamagata, but we must adapt our strategies to remain protected. Keeping vaccines up to date is crucial during flu season. And, let’s not forget, laughter can be a great medicine, but it certainly shouldn’t replace a flu shot!
**Interviewer:** Wise words indeed! Thank you for your time and insights today, Carsten. Stay safe and healthy!
