From Freakonomics M.D.:
After struggling to schedule a flu shot for his own toddler, host Bapu Jena went down a research rabbit hole. He discovered that the time of year kids are born has an unexpected and dramatic effect on whether they and their families end up getting the flu. Bapu explains his findings and asks a pediatrician and public health expert what could be done about it.
“It’s a public health issue,” Dr. Amol Navathe said. “One thing that is very different about flu and about other diseases that are transmittable from one person to another is how your neighbor behaves – the decisions they make – end up impacting you. It’s a strong social responsibility of every individual and every family to get their flu vaccine.”
