Lancet . 2021 Dec; 399(10319):36-49. PMID: 34883053
Background: Given the importance of flexible use of different COVID-19 vaccines within the same schedule to facilitate rapid deployment, we studied mixed priming schedules incorporating an adenoviral-vectored vaccine (ChAdOx1 nCoV-19...

Flaxman A, Marchevsky N, Jenkin D, Aboagye J, Aley P, Angus B, et al.
Lancet . 2021 Sep; 398(10304):981-990. PMID: 34480858
Background: COVID-19 vaccine supply shortages are causing concerns about compromised immunity in some countries as the interval between the first and second dose becomes longer. Conversely, countries with no supply...
