, muscle aches and pain, and changes to their skin and hair. This group had some of the “most severe and debilitating multi-organ symptoms,” the researchers wrote. The researchers found that the subtypes were similar in vaccinated and unvaccinated people based on the variants investigated so far. But the data showed that the risk of long COVID was reduced by vaccination.
In addition, although the three subtypes were present in all the variants, other symptom clusters had subtle differences among the variants, such as symptoms in the stomach and intestines.
“This opens new avenues of research to better understand COVID-19 and to motivate clinical research that might mitigate the long-term effects of the disease,” he said.King’s College London: “Three types of long-COVID for people experiencing symptoms for 12 weeks or more.”
