Summary
▪ Delta is different from previous strains – Highly contagious
– Likely more severe
– Breakthrough infections may be as transmissible as unvaccinated cases
▪ Vaccines prevent >90% of severe disease, but may be less effective at preventing
infection or transmission
– Therefore, more breakthrough and more community spread despite
vaccination
▪ NPIs are essential to prevent continued spread with current vaccine coverage
