Alternating doses of the Oxford-AstraZeneca and Pfizer-BioNTech vaccines generate robust immune responses against COVID-19, according to researchers running the University of Oxford-led Com-COV study.
Delayed second dose and third doses of the Oxford-AstraZeneca vaccine lead to heightened immune response
28 June 2021
Research on the ChAdOx1 nCoV-19, also known as the Oxford-AstraZeneca vaccine, indicates that a long interval between first and second doses does not compromise the immune response after a late second dose.

Researchers from the University of Oxford have today released their findings about the so-called ‘correlates of protection’ against symptomatic COVID-19; potentially a tool to speed up safe development of new vaccines which may assist regulators in assessing the likely potency of any new COVID-19 vaccine without the need for Phase III efficacy trial data.
21 June 2021
A new study led by the University of Oxford has found that previous infection, whether symptomatic or asymptomatic, does not necessarily protect you long-term from COVID-19, particularly against new Variants of Concern.
COVID-19 vaccine messaging that focuses on personal benefits is most effective with those who are hesitant

Research, from Com-COV study comparing mixed dosing schedules of Pfizer / Oxford-AstraZeneca vaccines, shows increase in the frequency of mild-moderate symptoms in those receiving either mixed dosing schedule. Adverse reactions were short-lived, with no other safety concerns. Impact of mixed schedules on immunogenicity unknown as yet, with data to follow from this study.
