One thing to note is that the vaccine trials only tested symptomatic people for the virus. Neither Moderna nor Pfizer tested asymptomatic participants, so there is currently no way to know how effective the vaccines are at preventing asymptomatic transmission of the virus (which we know is a huge factor in its spread). We know that the vaccines help prevent a large percentage of people from getting obviously sick from Covid, but that's not the same thing as preventing them from contracting Covid at all, or from spreading it to others.During the Pfizer trials, there were approximately 21K people in both the trial and the control groups. In the vaccinated group, of the 21K people, 8 people contracted the virus. Clearly 8 is not 5% of 21,000 people.
