Summary,

Delta is different from previous strains Highly contagious Likely more severe Breakthrough infections may be as transmissible as unvaccinated cases Vaccines prevent more than 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 Vaccine breakthrough cases may reduce public confidence in vaccines Vaccine breakthrough cases are expected Will increase as a proportion of total cases as vaccine coverage increases Vaccine breakthrough cases will occur more frequently in congregate settings and in groups at risk of primary vaccine failure (i.e., immune compromised, elderly) Communication challenges have been associated with increasing proportions of cases vaccinated even when vaccine effectiveness (VE) remains stable Important to update communications describing breakthrough cases as “rare” or as a “small percentage” of cases 35,000 symptomatic infections per week with 162 million vaccinated December 14, 2020 – April 10, 2021 Vaccine effectiveness against infection, 91% among fully vaccinated; 81% for partially vaccinated 40% lower mean RNA viral load Shorter mean duration of detectable viral RNA (2.7 v. 8.9 days) Lower risk of febrile symptoms (25.0% v. 63.1%) Shorter mean duration of symptoms (10.3 v. 16.7 days) Vaccine effectiveness against hospitalization 88% No evidence of waning immunity through 20 weeks post-2nd dose Lower estimates of VE for mRNA vaccines among immunocompromised populations After 2 doses, 59 - 80% against infection Vaccines more effective against hospitalization/death illness infection Delta infections associated with higher viral load and duration of shedding India Lower cycle threshold (Ct) values in Delta breakthrough cases HCW, Ct 16.5 Non delta, Ct 19 Delta infection associated with longer duration of Ct values less than 30 18 days vs. 13 days for ancestral strains Delta variant vaccine breakthrough cases may be as transmissible as unvaccinated cases UK, Cases down a bit today Includes lateral flow tests https://ourworldindata.org/coronavirus https://coronavirus.data.gov.uk Saturday, 31st + Friday, 30th + 29,622 Thursday, 29th + 31,117 Wednesday, 28th + 27,734 Seven days of decline
