“It is clear that some individuals have a disproportional effect on disease dynamics,” researcher Rhiannon Edge said.
“This study suggests that vaccination strategies that target highly connected individuals within a network might limit the spread of infectious disease.”
They said this was because people who are connected within a social network can influence each other’s behaviour, even when not connected directly.
And sometimes this can work both ways.
“If an individual’s vaccination decision is affected by their immediate social circle, clusters of unvaccinated individuals can develop – and these clusters may then facilitate outbreaks of infection.”
PHE encourages healthcare workers and carers to get vaccinated because they could pass the infection on to vulnerable people with whom they come into contact.
Latest flu vaccine uptake figures from Public Health England show that more than 70% of people aged 65 and over have been vaccinated.
However, fewer than 50% of those aged under 65 with a health condition have been vaccinated, and only 43% of pregnant women.
In addition, 37% of all two-year-olds, 40% of all three-year-olds, and 32% of all four-year-olds have been vaccinated with the nasal spray vaccine as part of the childhood flu immunisation programme.
