A recent study from UMC Utrecht has shed new light on the relationship between COVID-19 vaccinations and excess mortality during the pandemic. Contrary to concerns, the research found that vaccinations did not contribute to the elevated death rates observed during the crisis. Rather, the study revealed that individuals who had received the vaccine had a considerably lower risk of mortality in the weeks following vaccination.
The study, which analyzed data from various demographics and vaccine types, showed that vaccinated individuals had a 44% lower chance of dying in the three weeks after vaccination compared to the weeks that followed. This protective effect was consistent across all age groups, genders, and health conditions, including those with chronic illnesses and prior COVID-19 infections. notably, the risk reduction was most pronounced in the first week after vaccination and persisted for at least 12 weeks, the longest period examined in the research.
Higher Mortality Risk Post-Infection
In stark contrast, the study also found that the risk of death was 16 times higher in the first three weeks after a confirmed COVID-19 infection compared to subsequent weeks. The mortality risk peaked in the second week after infection and then gradually declined. This heightened risk was particularly pronounced among the elderly, men, and those with multiple chronic conditions.
Prof. Patricia Bruijning-Verhagen,the lead investigator and professor of Vaccination and Infection Control Epidemiology at UMC Utrecht,emphasized the study’s findings,stating,”This study confirms the results of previous research that COVID-19 vaccination does not explain the excess mortality during the pandemic. Thes findings can help better inform the public and reinforce confidence in the safety and efficacy of COVID-19 vaccines.”
Global Impact: 15 Million Excess Deaths
Globally, the COVID-19 pandemic is estimated to have caused nearly 15 million additional deaths, far exceeding the 5 million reported COVID-19 deaths. This “excess mortality” encompasses both the direct effects of the virus and indirect consequences, such as disruptions to healthcare systems and economic instability. Vaccination has been a critical tool in mitigating these impacts, significantly reducing the severity of infections and preventing hospitalizations and deaths.
While rare, temporary side effects such as myocarditis, thrombosis, and neurological complications have been associated with vaccination. However, multiple studies across various countries have consistently demonstrated a protective effect of vaccination against mortality from all causes. This UMC utrecht study, with its unique design, further supports these findings by comparing mortality risks within the same individuals before and after vaccination, thereby minimizing confounding factors.
A Unique Approach to Understanding Vaccine Impact
The study’s innovative methodology focused on examining the short-term effects of vaccination on mortality within the same population, rather than comparing vaccinated and unvaccinated groups. This approach addressed potential biases related to differences in vulnerability, chronic conditions, and socioeconomic factors, providing a clearer picture of the vaccine’s impact on mortality.
As the world continues to navigate the long-term effects of the pandemic, studies like this one play a crucial role in informing public health strategies and maintaining trust in vaccination efforts. The findings underscore the importance of vaccination as a key component in reducing overall mortality and mitigating the broader impacts of COVID-19.

A groundbreaking study conducted in the Netherlands has shed new light on the relationship between COVID-19 vaccinations and short-term mortality risk.the research, which analyzed data from 396,765 individuals who passed away between January 2021 and April 2023, suggests that COVID-19 vaccinations are associated with a lower risk of death in the weeks following inoculation.
The study,published on medRxiv on December 12,2024,employed a unique research design known as a self-controlled case series. This method compared the risk of death within three weeks after vaccination to the risk of death beyond three weeks post-vaccination, using each individual as their own control. This approach effectively neutralized the influence of factors such as pre-existing conditions, socio-economic status, and overall vulnerability, providing a more accurate assessment of the vaccine’s impact on mortality.
Why Three Weeks?
The three-week window was chosen based on the typical timeline of immune activation following vaccination, during which side effects are most likely to occur.By focusing on this period, the study aimed to isolate any immediate effects of the vaccine on mortality risk.
According to the study’s lead author, Dr. Ingeborg Slurink,”This research design allows us to confidently attribute any observed differences in mortality risk directly to the vaccination,rather than to other external factors.”
Implications for Public Health
The findings of this study could have important implications for public health strategies, particularly in the ongoing effort to combat the COVID-19 pandemic. By demonstrating a reduced risk of death in the weeks following vaccination, the research reinforces the importance of vaccination as a critical tool in saving lives and mitigating the impact of the virus.
Dr. Paul Bruijning-Verhagen, one of the study’s co-authors, emphasized the importance of these findings: “This study provides robust evidence that COVID-19 vaccinations not only protect against severe illness but also contribute to a lower risk of mortality in the short term.This underscores the vital role of vaccination in our fight against COVID-19.”
Next Steps
While the study offers valuable insights, further research is needed to explore the long-term effects of COVID-19 vaccinations on mortality and overall health outcomes.The authors of the study have called for additional studies to corroborate these findings and to investigate the mechanisms underlying the observed effects.
For now, the message remains clear: vaccination continues to be a cornerstone of pandemic response efforts, offering significant protection against the worst outcomes of COVID-19.

The weeks following vaccination. This finding is especially significant as it counters concerns that vaccinations might contribute to excess mortality during the pandemic. The study, led by Prof.Patricia Bruijning-Verhagen from UMC Utrecht, highlights the importance of vaccination in reducing mortality risks and offers valuable insights for public health strategies.
Interview with Prof. Patricia Bruijning-Verhagen
Senior Editor: Prof. Bruijning-Verhagen, thank you for joining us today. Your recent study has generated a lot of interest. Can you start by explaining the key findings of your research?
Prof. Bruijning-Verhagen: Of course, I’m happy to discuss our findings. The study revealed that individuals who had received the COVID-19 vaccine had a 44% lower risk of dying in the three weeks following vaccination compared to the weeks that followed. This protective effect was consistent across all age groups, genders, and health conditions, including those with chronic illnesses and prior COVID-19 infections.Notably, the risk reduction was most pronounced in the first week after vaccination and persisted for at least 12 weeks.
The Protective Effect of Vaccination
Senior Editor: That’s quite a significant reduction. Can you elaborate on why the risk of mortality was higher post-infection compared to post-vaccination?
