Discuss clonal selection theory in human physiology and it application in rubeola infection in a 6 year old child

Clonal selection is that activation of the lymphocyte lineage that recognizes a certain pathogen and as a consequence the stimulation of its replication, in the case of rubella disease it has a vaccine, and in this way the organism has an immunity mechanism previously received as other diseases, the vaccine is known as MMA where it protects in addition to two other diseases, so when injecting the vaccine an inactive portion of the virus is inoculated that generates a first contact or first infection with the body's defense cells, in this At this point, the lymphocyte lineage together with other cells form specific antibodies against this virus so that when there is a second infection (that is, when the virus enters completely in order to infect the body), the lymphocytes detect it as said pathogen, destroy it and they did not allow

The development of the disease.

clonal selection can be said to occur when there is a second encounter with the virus and the organism, since lymphocytes not only detect the pathogen but also replicate those that can detect it.

Rubella can prevent direct contact with infected people from being avoided.

Explanation:

Rubella is a viral disease that generates mucocutaneous eruptions and is usually accompanied by a feverish condition with lymphadenopathy.

It is very important that the child is vaccinated with the MMA vaccine since if this is not the case, this disease could be lethal for the child, not only because clonal selection or acquired immunology (memory immunology) does not occur, but because In addition, children at 6 years of age are considered not to have an overdeveloped immune system simulating possible immunosuppression symptoms, which is why it is necessary to take maximum care and hygiene with young children.
