If a more transmissible strain becomes dominant, “that level of coverage needed for herd immunity would become higher, in the 80 to 85 percent range,” Jay Butler, deputy director of CDC. https://t.co/jfyrxQen5A — Petra Khoury (@petra_khoury) February 1, 2021

Pfizer, Moderna and AstraZeneca have all begun clinical trials testing their #COVID-19 vaccines in children & they could have data from their trials by summer. — Petra Khoury (@petra_khoury) February 1, 2021

Immunity threshold of 80-85% includes children. About 23% of LEB is under age of 14. Today, none of the approved vaccines can be used in <16yrs. Until data from children trials are out; we need to vaccinate 100% of adults to get to max 77% given no kids under 16 can be vaccinated — Petra Khoury (@petra_khoury) February 1, 2021

Road to immunity may become HARDER & longer. Based on the #B117 #COVID19 variant contagiousness formula, it is 40-80% higher & might become dominant next. So instead of needing 70% immunity to stop the spread, we will need 80-85% of our population immune. — Petra Khoury (@petra_khoury) February 1, 2021
