Jabs work better on men in morning, say study

LONDON: The time of the day does matter when it comes to giving shots to men and women, claims a new study.
Researchers at the University of Birmingham have carried out the study which suggests that by vaccinating men and women at different times of the day could help to ensure that the jab can boost their immunity against the disease, according to the researchers, The Sunday Telegraph reported.
They believe that sex hormones like testosterone may be responsible for a change in the response to vaccines through the day. Also men tend to have higher testosterone levels in the morning.
They found that a month after being given either Hepatitis A or a flu vaccination, the antibodies in the men who were injected in the morning were higher than those injected in the afternoon. There was a small increase among women injected in the afternoon.
Dr Anna Phillips, who led the study, said, “The effect was biggest for men. It wasn’t statistically significant in women but seemed to be heading in the right direction.”
