Nog een studie, vaccins beschermen nauwelijks tegen de zogezegde long-covid. Ze spreken van 15% maar dat is statistisch niet relevant omdat er geen rekening werd gehouden met bestaande medische toestand van de mensen.
Van de meer vage symptomen was er 0% verschil tussen vaxx en unvaxx.
Vaccination against SARS-CoV-2 lowers the risk of long COVID after infection by only about 15%, according to a study of more than
13 million people

The authors of the latest study also compared symptoms such as brain fog and fatigue in vaccinated and unvaccinated people for up to six months after they tested positive for SARS-CoV-2.
The team found no difference in type or severity of symptoms between those who had been vaccinated and those who had not. “Those same fingerprints we see in people who have breakthrough infections,” Al-Aly says.
“Generally speaking, this is horrifying,” says David Putrino, a physical therapist at Mount Sinai Health System in New York City who studies long COVID. He praises the study, which was difficult to perform because of the amount and quality of data, but adds that it is limited because it does not break the data down by key factors, such as the participants’ medical history. “These are very important questions we need answers to,” Putrino says.
“We don’t have any really well constructed studies just yet.”
“We have no data on whether Omicron causes long COVID,” he says. The findings, he adds, “apply to a pandemic that has changed dramatically”. However, Deeks adds, the results do point to the need for more research on long COVID, and for accelerated development of therapies.
“We don’t have a definition, we don’t have a biomarker, we don’t have an imaging test, a mechanism or a treatment,” he says. “We just have questions.”
