Dataset 3 suggests that as the vaccine rate increases, the number of affected cases decreases, and the transmission of the disease is prevented, as no individuals would get infected. When the vaccine coverage rate reaches herd immunity, the transmission rate is essentially zero, thus the incidence rate is zero.

Dataset 3 suggests that as the vaccination rate increases, the number of affected cases decreases, and the transmission of the disease is prevented, as no individuals would get infected. When the vaccine coverage rate reaches herd immunity, the transmission rate is essentially zero, thus the incidence rate becomes zero.

To fix the grammar in the given sentence, you can make the following revisions:

"Dataset 3 suggests that as the vaccination rate increases, the number of affected cases decreases, and the transmission of the disease is prevented since no individuals would get infected. When the vaccine coverage rate reaches herd immunity, the transmission rate becomes essentially zero, resulting in a zero incidence rate."
