Several years after the first injections, persistent side effects are still a cause for concern. Chronic fatigue, heart problems, muscle pain… some symptoms remain unexplained four years later.

Four years after the start of the Covid vaccination campaign, thousands of people are still reporting persistent symptoms. This situation has rekindled the debate about the long-term effects of Covid vaccines.

Long-lasting symptoms reported after Covid vaccination

Since 2021, Covid vaccines have been widely administered. In France, as elsewhere, millions of people have received multiple doses. While the majority have responded well to the vaccine, a significant minority report lasting side effects.

Chronic fatigue, joint pain, migraines, and concentration problems… These symptoms all have one thing in common: persistence. They don’t disappear, even after several months. Some reports suggest a marked deterioration in quality of life since receiving the Covid vaccine.
