Terry Omara used to push himself hard to stay healthy — even while caring for his elderly mother. The London taxi driver, from Sutton, says he was walking marathon-length distances every other day.

In 2020, he battled Long Covid and became seriously ill with pneumonia and sepsis. By the following year, he believed he’d recovered and was back to normal.

That changed in 2022, he says, after receiving the Moderna Covid vaccine. Mr Omara, now 60, claims he developed intense pain and crushing fatigue soon afterwards. He was later assessed by a specialist and diagnosed in 2023 with Chronic Fatigue Syndrome (CFS).

Today, he says everyday tasks feel impossible. He reports being largely bedbound, managing a wash about once a week, and struggling with basic lifting — even a shopping bag. While the pain has eased somewhat, he says the exhaustion hasn’t. He has since moved in with his mother in Wallington, explaining he’s too unwell to live alone.

Mr Omara says he previously had Pfizer and AstraZeneca vaccines without noticeable side effects, and believes the Moderna shot is the only clear trigger he can identify.

CFS can cause extreme fatigue, “brain fog,” and difficulty concentrating. Covid vaccines have prevented millions of deaths, but researchers continue to investigate reports of rare, ongoing symptoms — including a recently discussed “post-vaccination syndrome” linked to mRNA vaccines.
