The student who caught the cold caused by this specific Rhinovirus was exposed to the exact same Rhinovirus 18 months later. Memory B cells of the immune system will protect her from getting the same cold again.
In immunology, a memory B cell (MBC) is a type of B lymphocyte that forms part of the adaptive immune system. These cells develop within germinal centres of the secondary lymphoid organs.
Memory B cells circulate in the blood stream in a quiescent state, sometimes for decades. Their function is to memorize the characteristics of the antigen that activated their parent B cell during initial infection such that if the memory B cell later encounters the same antigen, it triggers an accelerated and robust secondary immune response.
Memory B cells have B cell receptors (BCRs) on their cell membrane, identical to the one on their parent cell, that allow them to recognize antigen and mount a specific antibody response.

You could cover the sand dunes with tarps that are attached into the ground with stakes, or routinely spray them with lots of water to make the sand heavier and less likely to be picked up by wind.
Screening someone's blood and the biomolecular revolution would not have been possible without the human genome project.
<h3>The human genome project</h3>
The human genome project was initiated around 1990 with the aim to obtain the sequence of genes in an individual. It seeks to obtain the accurate arrangement of DNA in human beings.
<h3>Impact of the human genome project</h3>
The human genome project has made it possible to study all the genes in human beings and made us able to have a better view of biomolecular science.
Hence, screening someone's blood and the biomolecular revolution would not have been possible without the human genome project.
