📚 Summary

Four years on from the COVID-19 pandemic:

Long COVID is real, well-documented, and affects a significant minority of people after infection — lasting months to years with a wide range of symptoms such as fatigue, brain fog, respiratory problems, and cardiovascular symptoms.

COVID-19 vaccination remains safe and effective with the most serious side effects being rare and mostly short-term.

Reports of persistent symptoms after vaccination exist but are not yet scientifically validated as a common or causal long-term effect. Rigorous research continues.
