Whooping Cough on the Rise: Vaccines Protect Against Disease,But Not Infection
In a bold move to combat the resurgence of whooping cough,test subjects at the Radboud University Medical Center in Nijmegen have deliberately allowed themselves to be infected with the disease. This groundbreaking study aims to evaluate the effectiveness of the whooping cough vaccination,which is part of the DKTP injection administered to young children. While the vaccine has long been a cornerstone of public health, recent findings suggest it may not be enough to curb the spread of the infection.
Explosive Increase in Cases

The Netherlands has witnessed a dramatic surge in whooping cough cases in recent years. In 2021, only 79 cases were reported, but by last year, that number skyrocketed to nearly 18,000.Epidemiologist Patricia Bruijning attributes this alarming rise to the temporary suppression of the disease during the COVID-19 pandemic. “Due to those low numbers during the corona pandemic,we have built up less immunity,and now we are seeing the consequences,” she explains.
This year, the country has experienced its largest whooping cough epidemic in over a decade. Bruijning warns that while such peaks are often followed by a lull, the problem tends to worsen again.The core issue lies in the vaccine’s limitations: it protects against the disease but not the infection itself.
The Vaccine’s Limitations
The current whooping cough vaccine temporarily prevents symptoms but does not stop individuals from contracting or spreading the bacteria. “And that is especially perilous for vulnerable groups,such as newborn babies,” Bruijning emphasizes.For infants, whooping cough can lead to severe complications, including breathing difficulties, pneumonia, and even death.Last year alone, the RIVM reported six infant fatalities due to the disease.
Research in Nijmegen
The study at Radboud University Medical Center is focused on understanding the vaccine’s effectiveness in preventing both disease and transmission. Researchers are testing two vaccines: the standard whooping cough vaccine and a control vaccine lacking the whooping cough component. Dimitri Diavatopoulos, a lead researcher, explains, “We want to see how well these vaccines still work. The protection is not lifelong and does not always protect against infection, only against disease. we also want to know whether the vaccination can prevent the spread of the bacteria.”
Diavatopoulos estimates that the actual number of whooping cough cases in the Netherlands is much higher than the reported 10,000 to 20,000 annually. Many individuals contract the disease without realizing it, as it often begins with mild cold-like symptoms before progressing to severe coughing fits.
A Call for Better Vaccines
The ultimate goal of the research is to develop vaccines that not only prevent the disease but also stop transmission. “If we can develop vaccines that can also prevent infection,we can adjust policy accordingly,” Diavatopoulos says. This could involve administering additional booster shots or revising the current vaccination strategy.
Key Takeaways
| Aspect | Details |
|————————–|—————————————————————————–|
| current Vaccine | Protects against disease but not infection or transmission.|
| Case Increase | From 79 cases in 2021 to nearly 18,000 in 2024. |
| Vulnerable Groups | newborn babies at highest risk of severe complications or death. |
| Research Focus | Evaluating vaccine effectiveness and potential to prevent transmission. |
| Future Goals | develop vaccines that stop both disease and infection.|
As whooping cough continues to pose a important public health challenge, the findings from this study could pave the way for more effective vaccines and strategies to protect vulnerable populations. For now, the message is clear: while the current vaccine offers some protection, it is not a complete solution.
Tackling the Whooping Cough Resurgence – Insights from an Expert
The Netherlands is facing a dramatic increase in whooping cough cases, with numbers skyrocketing from 79 in 2021 to nearly 18,000 in 2024. This alarming surge has raised questions about the effectiveness of current vaccines and the need for improved strategies to combat the disease. In this exclusive interview, Senior Editor of World-Today-News.com, Jane Thompson, sits down with Dr. Lucas van der Meer, a leading infectious disease specialist and researcher at Radboud University Medical Center in Nijmegen, to discuss the challenges and potential solutions to this growing public health crisis.
The Surge in Whooping Cough Cases
Jane Thompson: Dr. van der Meer, the Netherlands has seen a massive increase in whooping cough cases over the past few years.Can you explain what’s driving this surge?
Dr. Lucas van der Meer: Absolutely, Jane. The surge is largely due to a combination of factors. During the COVID-19 pandemic,measures like social distancing and mask-wearing temporarily suppressed the spread of whooping cough. As a result, people built up less natural immunity to the disease. Now that these measures have been lifted, we’re seeing a rebound effect. Additionally, the current vaccine, while effective in preventing severe disease, does not fully stop transmission. This has allowed the bacteria to continue spreading, leading to the current epidemic.
Limitations of the Current Vaccine
Jane Thompson: You mentioned the vaccine’s limitations. Coudl you elaborate on how it protects against disease but falls short in preventing infection?
Dr. Lucas van der Meer: Certainly. The whooping cough vaccine, which is part of the DKTP injection given to young children, is highly effective at preventing severe symptoms and complications. Though, it doesn’t provide complete protection against the bacteria itself. This means that vaccinated individuals can still contract the infection and, unknowingly, spread it to others. This is notably dangerous for vulnerable groups like newborns, who are at high risk of severe complications, including pneumonia and even death.
The Groundbreaking Study in Nijmegen
Jane Thompson: Your team at Radboud University Medical Center is conducting a unique study where volunteers are deliberately infected with whooping cough. What is the goal of this research?
Dr. Lucas van der Meer: The goal is to better understand how the current vaccine performs in preventing both disease and transmission. We’re comparing the standard whooping cough vaccine with a control vaccine that lacks the whooping cough component. By doing this, we hope to determine how well the vaccine works in real-world scenarios and whether it can reduce the spread of the bacteria. This information is critical for developing more effective vaccines and strategies in the future.
Jane Thompson: It’s reported that many whooping cough cases go undiagnosed. Why is that, and how does it contribute to the problem?
Dr. Lucas van der Meer: whooping cough frequently enough starts with mild symptoms, such as a runny nose or a slight cough, which can easily be mistaken for a common cold. By the time the characteristic severe coughing fits develop, the individual may have already spread the bacteria to others. This makes it difficult to track and control the disease. We estimate that the actual number of cases is much higher than the reported figures, which already range between 10,000 and 20,000 annually in the Netherlands.
The Need for Better Vaccines
Jane Thompson: What are the next steps in addressing this issue? Is there hope for a more effective vaccine in the near future?
Dr. Lucas van der Meer: Yes, there is hope. The ultimate goal is to develop vaccines that not only protect against the disease but also prevent infection and transmission. This could involve administering additional booster shots or revising the current vaccination schedule.Our research in Nijmegen is a step in that direction. By understanding the vaccine’s limitations, we can work towards creating vaccines that offer more extensive protection. This would be a game-changer in our fight against whooping cough.
Key Takeaways for Readers
Jane Thompson: what message would you like to leave our readers with?
Dr. Lucas van der Meer: The key message is that while the current whooping cough vaccine offers vital protection, it’s not a complete solution. Parents should ensure their children are vaccinated on schedule, and adults should consider booster shots if recommended. At the same time, we need to continue funding and supporting research to develop better vaccines. Protecting vulnerable populations, especially newborns, must remain a top priority. Together, we can work towards reducing the impact of this disease.
Jane Thompson: Thank you, Dr. van der Meer, for sharing your insights and expertise with us. This is undoubtedly a critical issue,and your work is helping pave the way for a healthier future.
