Huge study finally reveals outcome for people who took Covid vaccine

A major study into the Covid-19 vaccine has revealed surprising results for everyone who took the jab.

It's been six years since the first case of Coronavirus was detected in Wuhan, China in December 2019, a virus which would spread around the world and see numerous nations enforce strict lockdown rules on their citizens.

Around 7,102,614 people worldwide are understood to have died from the respiratory disease, with 227,000 people in the UK having the disease listed as their cause of death, the BBC reports.

Years on from the pandemic, and Covid still exists, but is less devastating on the body following mass vaccination programmes and the virus evolving into a milder strain.

The vaccine rollout was widely successful, with an estimated 67 percent of the world's population having taken the Covid vaccine by December 2023, per WHO. However, it wasn't without its problems.

Online misinformation led to growing mistrust in the vaccine, while cases of rare side effects associated with the drug also raised concerns.

So, how successful was the vaccine overall?

Very, according to one study.

Published in the journal JAMA Network Open, researchers compared vaccinated and unvaccinated adults in France between the ages of 18 and 59 and found a 25 percent lower risk of all-cause death in the participants who'd been vaccinated.

A total of 22.7 million vaccinated individuals and 5.9 million unvaccinated people - around 40 percent of France's total population - took part in the study.

Adults eligible to be included in the vaccinated group were required to have had at least one dose by 1 October 2021, with the majority of participants having received two doses of either Pfizer or Moderna.

Meanwhile, the unvaccinated participants were people who hadn't received a jab by 1 November 2021.

The study also revealed that vaccinated adults had a 74 percent lower risk of dying in hospital from Covid complications.

However, researchers did note limitations in the study, such as vaccinated individuals having better rates of mortality due to being of higher socioeconomic status, which meant they may have access to preventative healthcare.

The study follows concerns about links between the Covid vaccination and side effects such as myocarditis and pericarditis.

Considered to be a rare side effect, impacting up to 1 in 10,000 people vaccinated, the conditions relate to inflammation of the heart's muscle and lining.

Various studies have been conducted to further understand why this occurs, with researchers noting that you have a higher chance of developing myocarditis and pericarditis from Covid itself rather than the vaccine.
