Interpretation
Vaccination reduces the risk of delta variant infection and accelerates viral clearance.
Nonetheless, fully (Prof N M Ferguson DPhil), and vaccinated individuals with breakthrough infections have peak viral load similar to unvaccinated cases and can efficiently transmit infection in household settings, including to fully vaccinated contacts. Hostvirus interactions and Technology early in infection may shape the entire viral trajectory.
