Receiving two COVID-19 vaccine doses may heighten the risk of Long Covid, according to new research. The Epoch Times has the story.
In the study published in PLOS One, researchers examined data from 487 and 371 individuals at four weeks and six months post-SARS-CoV-2 infection, respectively, to estimate the incidence, characteristics and predictors of Long Covid among patients. Long Covid symptoms were reported by 29.2% of participants four weeks following infection. This number dropped to 9.4% at six months, indicating symptoms may diminish over time.
Researchers found that the greater the severity of infection a patient had, the more likely they were to experience Long Covid. The incidence of Long Covid at four weeks of follow-up in those who experienced mild/moderate disease was 23.4% compared with 62.5% in those with severe cases.
At six months, the incidence of Long Covid was considerably lower. For those with mild/moderate infection, only 7.2% reported symptoms compared with 23.1% in those with severe/critical cases. The most commonly reported symptom was fatigue. Other symptoms included cough, cognitive dysfunction or brain fog and loss of taste and smell.
During the four-week follow-up, patients were more likely to experience Long Covid if they had pre-existing medical conditions, a higher number of symptoms during the acute phase of COVID-19 illness, if their infection was more severe or resulted in hospitalisation, or if they had received two COVID-19 vaccine doses.
Although previous vaccination was associated with Long Covid, the authors could not find “any interaction effect of COVID-19 vaccination and acute COVID-19 severity on causing Long Covid.”
This implies that prior vaccination “was independently associated with the occurrence of Long Covid”, cardiologist Dr. Peter McCullough explained in a recent Substack post.
