Vaccinations are more effective when administered in the morning
University of Birmingham

New research from the University of Birmingham has shown that flu vaccinations are more effective when administered in the morning.

The findings, published in the journal Vaccine, suggest administering vaccinations in the morning, rather than the afternoon, could induce greater, and thus more protective, antibody responses.

•••••

In two of the three given influenza virus strains, those in the morning cohort saw a significantly larger increase in antibody concentration one month following vaccination, when compared with those in the afternoon cohort. In the third strain, there was no significant difference between morning and afternoon.

•••••

The influenza vaccination is part of the seasonal vaccination programme carried out by general practices across the UK, and in many other countries, with a particular focus on patients over 65 years old.

Despite this, the influenza virus is responsible for between 250,000 and 500,000 deaths each year worldwide. The age-related decline in immunity reduces the ability of older adults to produce adequate antibody responses following vaccination, compromising the given protection.
