Get vaccinated, y’all.

The study makes it sound like it wouldn't matter.

I've gotten the COVID vaccine each year and already have had COVID two times. It was mild but the study specifically says that mild COVID can be a contributor.

There was also some new information that vaccinated or not, severe or mild, didn't matter when it came to the neurological outcomes from COVID infections. Vaccines cut death/acute severity way down, but verdict is out on all of the other myriad damage COVID is still doing through the body. We don't know enough about COVID to let it rip like we did.

According to new research published in Brain Communications, Northwestern Medicine researchers found that vaccination prior to COVID-19 infection did not significantly affect neurological symptoms in long COVID patients, both in patients who had a severe infection that required hospitalization and those with a mild infection who did not require hospitalization. Common neurological symptoms of long COVID include brain fog, numbness and tingling, headache, dizziness, problems with smell and taste and intense fatigue.
