A memory B cell is kinda of how it sounds it has a memory of what your body has fought before such as a virus and can stimulate a response quicker then the first time you encountered it.
If you lack memory B cells your body doesn't built up the same immune response when you come into contact with the virus again.

"Vaccination would not prevent further disease" Correct, a vaccine can be a dead version of a virus or parts of a virus that shows your body what to respond to quickly in the future. If you body cannot make memory b cells it wouldn't help to use a vaccine. Your body wouldn't keep a memory of it being bad.
"You would not produce antibodies" Even if your body does not remember a particular virus it does produce antibodies to combat it just not as quick or efficiantly as something it has come into contact with before and produced memory cells.
"You would over produce histamine" Incorrect, different process for that histamine.
Doubtlessly the germination rate of the radish seeds is more noteworthy when the pH is more unbiased, similar to when putting in water. There wasn't any distinction in the development of the radish seeds between the soluble and acidic arrangements in my analysis. The seeds did not develop in either arrangement. The radish seeds appeared to endeavor to develop in the acidic arrangement. The reason I say endeavored to develop is on account of you could see greenish spots where the seeds were put. The radish seeds had no adjustment in the antacid arrangement. Neither one of the solutions is a decent situation for radish seeds to develop.
