Spiky Patch Capable of Invisibly Keeping a Record of Vaccination History under Skin

The human body is naturally an incredible record keeper.  There is an astounding record of scars of old wounds under skin and traces of past infections archived in the molecules of the immune system.  However, it is believed that when this information is translated into written medical records things can become risky.  Therefore, a team led by MIT scientists has introduced the bold proposition that could write a legible vaccination history back into body’s repertoire.

This would eventually help the health providers to access patients past vaccinations without relying on external medical records.  However, this technology has raised several ethical concerns which could hinder its progress.
