Switzerland has just dropped a bombshell study that should send shockwaves through every health authority still pushing endless Covid mRNA “booster” shots.
A major new investigation has revealed that instead of protecting frontline healthcare workers, repeated Covid “vaccines” were actually linked to higher rates of illness and more missed workdays.
The findings, published in the medical journal Communications Medicine, raise urgent questions about the safety and effectiveness of mRNA technology, which was long promoted as the “only way out” of the pandemic.
The study, led by Dr. Tamara Dörr of Cantonal Hospital St. Gallen and colleagues at the University of Zurich, tracked 1,745 healthcare workers across nine Swiss hospital networks between November 2023 and May 2024.
Instead of keeping staff healthy, the so-called “boosters” appeared to do the opposite.
Workers with three Covid shots had a 56% higher risk of influenza-like illness (ILI).
Those with four doses fared even worse, with a 70% higher risk compared to the unvaccinated.
More recent vaccination was linked with more illness and more missed workdays — the opposite of what public health leaders promised.
Meanwhile, seasonal flu shots worked as expected — reducing both illness and absences.
Nearly half the healthcare workers in the study reported falling ill at least once during the season, and almost 50% missed days of work.
The researchers cautiously suggested that immune imprinting or immune system disruption might be at play.
In plain terms: repeated boosters may be rewiring the immune system in harmful ways.
And it’s not the first time warnings like this have surfaced.
As Slay News has reported, studies from Japan, Europe, and the U.S. have already flagged alarming spikes in autoimmune issues, cardiovascular problems, and even sudden deaths following repeated Covid mRNA shots.
Now, Swiss data adds another red flag: short-term vulnerability to illness and incapacity among “vaccinated” healthcare workers, the very people expected to keep hospitals running.
The authors admit the study is observational and based on symptom reporting, not lab-confirmed diagnoses.
However, the findings were consistent across multiple analyses, and the trend was undeniable: more boosters, more sickness.
This comes as the World Council for Health and top experts worldwide are increasingly calling mRNA shots biological weapons that should be banned outright.
We also recently reported on Japan’s leading doctors warning of deadly post-booster lung inflammation, and Mississippi declaring a public health emergency after infant deaths spiked, with growing suspicion about “vaccine” ties.
In Japan, doctors have sounded the alarm after a 77-year-old man developed life-threatening lung inflammation just two days after his third Pfizer booster.
Researchers at Nagoya City University reported the case as proof of a dangerous immune overreaction linked to mRNA shots, highlighting how boosters may be triggering cytokine storms that leave patients fighting for their lives.
Mississippi has also declared a public health emergency after its infant mortality rate hit the highest level in more than a decade.
Officials admitted that more than 3,500 babies have died before their first birthday since 2014, and while causes range from premature birth to congenital issues, health freedom advocates warn that the timeline coincides disturbingly with the rollout of Covid shots for pregnant women.
Meanwhile, the World Council for Health Florida recently went further than any other health body yet, officially declaring mRNA injections to be “biological and technological weapons of mass destruction.”
The group endorsed the Sansone mRNA Bioweapons Prohibition Act, a bill already introduced in multiple state legislatures, which would criminalize officials who fail to act against these injections.
This broader picture, from Japan to Mississippi to Switzerland, shows a consistent and chilling pattern: The more mRNA technology is forced on populations, the more red flags emerge.
