Massive new study finally uncovers outcome for everyone who received Covid vaccine

It's five years since the first vaccine was administered

No matter what your thoughts on the pandemic are, and whether you agree we were right to be vaccinated or not, there's no escaping the fact that COVID-19 reshaped the world.

More than just changing how we work as more people than ever learned to work from home, it affected relationships as people were left isolated, triggered high inflation by quickly adding $3.1 trillion to the USA's public debt, and brought the travel industry to its knees alongside many other sectors.

Still, with 7,103,462 reported COVID-19 deaths, and 46 of them being in the last seven days alone, it's a threat that needed to be taken seriously.

There was a massive amount of Covid misinformation, with President Donald Trump among those fuelling the fires of conspiracy.

Despite it being six years since the first case was reported in Wuhan, China, the effects of Covid are still being felt.

At a time when the USA has been trying to ban the vaccine, others have heralded it as a life-saving prevention that helped the world return to some sort of normality sooner than it could have.

Away from news that a new virus that's 'worse' than Covid could be on the horizon, a new study reveals what the vaccine has done to us all those years later.

While Secretary of Health RFK Jr. says we were 'lied' to about the vaccines, and Elon Musk claiming he was hospitalized after getting his, new research published in the JAMA Network Open journal suggests otherwise.

Researchers looked at 22.7 million vaccinated and 5.9 million unvaccinated individuals in France, meaning about 40% of the country's population took part. All were between the ages of 18 and 59, with the study showing that vaccinated participants were 25% less at risk of all-cause death.

Those who took part had to have at least one dose by October 1, 2021, although most had been given either two doses of Pfizer or Moderna.

The unvaccinated contingent had to not have received a jab by November 1, 2021.



📊 New 4-Year Study: mRNA COVID Vaccines & Mortality

A 2025 JAMA Network Open study followed 28 million French adults (18–59) for almost 4 years. Key takeaway:

👉 No increased long-term mortality from mRNA COVID vaccines.

In fact, vaccinated adults had a 25% lower risk of…

Diving deeper into the stats, the vaccinated subjects had a 74% lower chance of dying from Covid complications while in the hospital.

Across the board, the study reports that there's no increase in deaths from cancer, heart disease, accidental injury, or any other major category for those who are vaccinated. In every case, they had equal or lower rates of death.

Researchers noted there were some limitations, such as vaccinated patients having a better mortality rate due to a typically higher socioeconomic status and having access to preventative healthcare.

Still, the figures are in contrast to fears that the vaccine can lead to side effects like myocarditis and pericarditis.

While these conditions have devastating consequences, like causing inflammation of the heart's muscle and lining, it's a rare side effect that's thought to impact one in every 10,000 people who are vaccinated.

The researchers maintain that you're more likely to develop myocarditis and pericarditis from Covid instead of the vaccine.

Then again, with more research needing to be done, don't expect the anti-vaxxers to suddenly concede.
