Answer:
Multiple Sclerosis is an inflammatory disease in which myelin sheath of nerve cells of brain and spinal cord are damaged.
Explanation:
Cause:- (Exact cause of inflammation is not known)
- But damage is caused due to attack by autoimmune cells or antibodies against myelin sheath.
Types of tissues attack:-
- Oligodendrocytes and myelin sheath is damaged and stripped away from axon and the process is known as demyelination.
- Myelin sheaths are made up of fatty tissues and help in transmission of electric impulse.
Result of immune system attack:-
- Damaged myelin sheath stop forming whIte matter of central nervous system.
- Hence disrupt coordinating communication between different brain regions.
Signs and symptoms:- vary from person to person
- Diminished eyesight.
- Disrupt motor coordination.
- Weak sensory perception.
- Fatigue and dizziness.
- Speech disorder.
- Muscle weakness and spasticity.
- Difficulty in urination and stool.
Diagnosis and treatment:-
- Diagnosis include MRI T2 findings and cerebrospinal fluid specific oligoclonal bands.

It would happen that the effectiveness of an original vaccine could become less if there was a mutation in the virus that caused the protein spike to change because the antibodies created would not be specific for the new virus.
<h3>What would happen to the mutated virus?</h3>
Vaccines trigger an immune response to fight disease-causing organisms, a mutation in the virus to be fought would change the effectiveness of this immune response, as the specificity would not be the same with the mutant virus.
With this information, we can conclude that The immune response would not be specific for the new virus that caused the protein spike to change.
