Van Cott and colleagues also found that the clinical decline toward DIC was foreshadowed by a measurable change in the shape, or waveform, of a plot charting light absorbance against the time it takes blood to coagulate. They both are what are called mRNA vaccines, which function very differently than the types of vaccines used in the past.
