The vaccine may not be as effective for you as it was shown to be in the pre-authorization trials. Real-world factors in vaccine storage and administration may have an impact. And your health is unique. The level of population immunity necessary to limit vaccine spread is unknown.

Clinical trials did not assess whether vaccination decreases viral transmission and prevents asymptomatic infection, as distinct from its proven value in decreasing the risk of getting sick. Thus, public health measures need to continue unabated.
