A new preprint from the UK Coronavirus Immunology Consortium and the University of Birmingham looks at the antibody and cellular immune responses in people aged 80 years or older after 2 doses of the BNT162b2 mRNA vaccine with either a 3-week or 11-12 week dosing interval.
As far as the authors are aware, this is the first study in the world to directly compare the immune responses generated by a 3-week versus a 12-week dosing schedule for this vaccine for any age group.
Please note this data is a preprint, so it is early work that has not yet been through peer-review and is not published in a journal.
Journalists dialled in to hear the study investigators present their results and answer any questions.
