A healthy man was struck by a life-threatening inflammation of his brain and spinal cord after just one dose of a Covid vaccine.

The unnamed 60-year-old sought help from medics in Paris, France after suddenly developing walking problems and mental confusion, four weeks after receiving a dose of AstraZeneca’s Covid jab. 

Brain scans revealed he was suffering from meningoencephalitis—a life threatening swelling of the brain and the tissue surrounding the brain and spinal cord—according to doctors who shared his tale in a medical journal.

While the condition can be caused by health problems like an infection or blood cancers, analysis of the man’s brain tissue showed no signs of any viruses or other disease that could be responsible

This led medics to believe that the man’s swelling was caused by his Covid vaccination, specifically his immune system over-reacting to the jab. 

They then diagnosed him with postvaccinal encephalitis, dangerous brain swelling following a jab.

The man, who suffered two bouts of brain swelling while in the care of the medical team, was treated with special drugs to suppress his immune system for six months until his symptoms were under control.

Doctors, who reported the case JAMA Neurology, said the man had made an almost full recovery three years after.

However, they noted he continued to suffer from ongoing mild problems with his attention span. 

The patient originally showed significant improvement after being treated when he first suffered symptoms four weeks after getting the jab.

However, he returned with the same walking and mental confusion problems three months later which when medics conducted the brain biopsy and put him on six months of medication. 

Medics said the relapse showed the importance of sustained drug treatments for such patients as well as ‘prompt diagnosis and aggressive treatment’.

Encephalitis after Covid vaccines have been reported before. 

A study published in 2023 on 65 patients found AstraZeneca was the most common vaccine brand linked to the reaction, accounting for over a third of cases.

The authors of that report highlighted that what exactly causes vaccine induced encephalitis to occur in some patients is not yet understood. 

However, they added that majority of cases have made a full recovery. 

While the team behind the most recent report did not specify when the man received the Covid jab it is likely to have been in 2021.

Researchers tasked with investigating the adverse reaction believe it occurs due to the modified cold virus lurking in the jab acting like a magnet to a type of protein in the blood called platelet factor 4. Platelet factor 4 is normally used by the body to promote coagulation in the blood, in case of injury. Then, in rare instances, the body’s immune system confuses platelet factor 4 with a foreign invader and releases antibodies to attack it in case of ‘mistaken identity’. These antibodies then clump together with platelet factor 4, forming the blood clots that have become so heavily linked with the jab, according to their theory

France—alongside many European countries—suspended and then restricted the use of the British designed jab in early 2021.

This followed reports of a small number of patients suffering an extremely rare but potentially deadly blood clotting reaction. 

Called thrombosis with thrombocytopenia syndrome (TSS), this is a medical condition where a person suffers blood clots along with a low platelet count. Platelets typically help the blood to clot.

The complication—missed in initial safety trials due to its rarity but now listed as a potential side effect of the jab—has also previously been called vaccine-induced immune thrombotic thrombocytopenia (VITT). 

Health officials first identified cases of VITT linked to AstraZeneca’s jab in Europe as early as March 2021, just over two months after the vaccine was first deployed in the UK. 

However, it wasn’t until April that year that evidence became clear enough that the jab started to be restricted.

Officials first stopped dishing out the jab to people under the age of 30. They then expanded this to only people over 40 in May 2021. 

As the vaccine still worked against Covid, it was still deemed worth giving to older Britons who were at greater risk of death or injury from falling ill with the virus.

The AstraZeneca vaccine is a genetically engineered common cold virus that used to infect chimpanzees. It has been modified to make it weak so it does not cause illness in people and loaded up with the gene for the coronavirus spike protein, which Covid-19 uses to invade human cells

Jack Last, 27, died at Addenbrooke’s Hospital in Cambridge on April 20 2021  just a few weeks after getting the Oxford AstraZeneca jab

About 50million doses of the AstraZeneca jab were dished out in the UK in total.  

Official data shows at least 81 Brits have died from blood clot complications apparently linked to the AstraZeneca jab, according to figures collected by the UK’s drug watchdog, the Medicines and Healthcare products Regulatory Agency.

A further unconfirmed number have been injured and/or disabled.

Further Covid vaccine rollouts have either minimised use of the AstraZeneca jab and/or phased it out entirely in favour of alternatives like those made by rival pharma giants Pfizer and Moderna.

With health officials not ordering any more doses, this effectively means the jab has all but been withdrawn in the UK.

While rare reactions to the jab has been linked to deaths and injuries, AstraZeneca’s shot is credited with saving some 6million lives globally during the Covid pandemic.

The latest NHS figures show 293 Britons—or their families— have applied to a Government scheme to support the vaccine injured and had their claim the jab caused their health issues accepted. 

However—under the rules of the widely criticised scheme—not all will receive the £120,000 compensation offered.

Survivors of jab injuries must be at least 60 per cent disabled by their injuries in order to qualify for a payout—for example losing a limb, a sense like your sight, or suffering complete paralysis. 

The case of the French man comes amid growing concern about what has been dubbed ‘post-vaccination syndrome’.

Linked to mRNA jabs, those made by the likes of Pfizer and Moderna but not AstraZeneca, the condition appears to cause brain fog, dizziness, tinnitus and exercise intolerance, the researchers reported.

Some sufferers also show distinct biological changes, including differences in immune cells and the presence of coronavirus proteins in their blood, years after taking the shot.

The condition is also said to increase the risk of reawakening a dormant virus called Epstein-Barr, which can cause flu-like symptoms, swollen lymph nodes and nerve issues.

The full results of the small study have not yet been published or peer reviewed, and the authors emphasised the results ‘are still a work in progress.’
