Is original antigenic sin a big problem for vaccine safety and efficacy?

Dr. Merzenich, At the age of 19 I contracted viral Encephlomyelitis from a presumed enteroviral source. It was a long and ardorous healing process, and I can tell it made changes to my memory. My visual memory seems to be taking over for the pneumonic memory. (I now recall test material better by "reading the words in the textbook again in my minds eye" during tests, as opposed to word memorization, which mine has deteriorated.)

My question is, can neuroplasticity be jump started by inflammatory challenges such as encephalitis?
