Having the time to spend on getting vaccinated at the Pusat Kesihatan yesterday reminded me a portion of my A lvl Biology X) mannn~its a shame that I have to leave my biology..Though I will study about fossils..At least its about animals' fossils but im not sure I will study about plants' fossils though.
One of the things that im interested in palaentology is 'foraminifera' *drools..Being a Stratigrapher is kinda awesome too =] *drools..2xcombo
During Vaccinations, according to what I have been taught in my A lvl..Antigens are being inserted to our blood. They are harmless though. The white blood cells then detect the antigens and therefore through some biological processes produce memory cells(so the body remembers the specific antigen next time it invades the body) and also some specific white blood cells used to attack & destroy the antigens. Example, bird flu vaccination..Where we will be injected an amount of antigens identical to those of the bird flu's antigens. Thus, our body able to produce not only white blood cells to eliminate the antigens but also memory cells which are VITAL.
Why they are vital?
Its because, with memory cells, the antigens invading our body will be destroyed quicker and thus making our body not to suffer any of the negative effects caused by those antigens.
Informations above MAY not be Accurate. Its best you seek the correct theory and biological terms from your tutors =)
