To help you fight any viruses, the third line of defense comes into play. Two types of Cells make up the third line of defense; B-Cells and T-Cells. A B-Cell is a lymphocyte that is responsible for producing antibodies and creating long term immunity. A T-Cell is also a lymphocyte that actively participates in the immune response, provide long term memory and that also kills infected cells
There are also different types of B & T Cells, they each have different functions: For B-Cells, the Plasma B attacks the pathogen with antibodies, while the Memory B help create long term immunity to create antibodies faster if the pathogen comes back. For T-Cells, the Helper T activate B cells to divide when antibodies are needed, Killer T terminates cells otherwise known as Apoptosis or cell death, and Memory T are cells that provide the experience needed to fight off the pathogen.
And one final thing, remember that you must have all your required vaccinations done when attending a public school to prevent the spread of viruses.
