Is there a best time for a vaccine? In this episode of Light
O'Clock, we speak with Dr Cathy A. Wyse about whether the time of
day when we receive a vaccine can influence how we respond to it.

We first discuss how circadian rhythms shape the immune system,
how vaccines work, and the difference between vaccine response
(e.g., antibody levels) and vaccine effectiveness (i.e.,
protection against infection or disease). We then discuss why the
current evidence remains mixed and how factors such as
chronotype, sleep, age, sex, prior immunity, and vaccine type may
influence results.

The key message: the immune system is rhythmic, so timing could
matter -- but the evidence is not yet strong enough to recommend
one specific time of day for vaccination. For now, the most
important advice remains: get vaccinated when you can.
