I'm not sure I understand what you mean by short term effect, the first sentence in the article you linked mentions it's an incurable disease and it took them years to admit it was linked to Pandemrix.

English is not my native language so maybe I didn't understand what you meant by that.

I understand the confusion. I meant that the long-term narcolepsy was caused by something that happened in the short-term while the immune system was still reacting to the vaccine.

From that link:

> The flu vaccine is designed to trigger antibodies to influenza’s surface proteins, but if it elicits antibodies to the nucleoprotein as well, those might well latch on to the hypocretin receptor, and eventually lead to death of the cells, the researchers thought.

That couldn't just spontaneously happen a year after getting a vaccine.

Thank you for the explanation.
