The Lancet (11/01/24) published a study which evaluated whether COVID-19 vaccination prevents Long Covid symptoms and compared effectiveness of the ChAdOx1 and BNT162b2 vaccines. Large-scale electronic health records were analyzed from the UK, Spain, and Estonia.
Vaccinated individuals were significantly less likely to report long COVID symptoms 90-365 days after infection compared to unvaccinated individuals. The first vaccine dose provided a 46-59% reduction in Long Covid risk across the cohorts.
The BNT162b2 vaccine showed slightly greater effectiveness than ChAdOx1 in preventing Long Covid symptoms based on UK data, though the difference was not statistically significant.
The results consistently demonstrate COVID-19 vaccination, particularly the first dose, substantially reduces the risk of developing long-term COVID-19 symptoms. This highlights the importance of vaccination to prevent persistent post-COVID conditions.
In summary, this large real-world study provides evidence that COVID-19 vaccines, especially mRNA vaccines, are effective in preventing Long Covid. Widespread vaccination could significantly reduce long-term COVID-19 burdens. Further research is warranted on optimal timing and additional doses.

Durham County Department of Public Health have produced a great video demonstrating that covid and many other viruses are airborne. The video is less than two minutes long. An airborne virus is a virus that can infect other people through particles in the air, sometimes for hours after the sick person has left the area! […]
This narrative review shows that POTS, ME/CFS and Long COVID are closely related conditions that share common biological mechanisms. The authors explain that problems with the autonomic nervous system, immune dysregulation and autoimmunity, mitochondrial dysfunction, reduced blood flow to the brain, and neuroinflammation all play a role. POTS and ME/CFS are identified as the most […]
Summary: Comparing Long Covid symptoms between patients that received COVID-19 vaccinations and those that did not. Study by Pasculli et. al., (2025) summarised by Amanda Harrington-Vail Introduction Since the COVID-19 pandemic was officially declared, almost 780 million cases and nearly 7 million deaths have been reported worldwide. Although COVID-19 vaccination has reduced the risk of […]
