"Romina Libster: The power of herd immunity" was filmed in November 2014 at TEDxRiodelaPlata.

Summary
"How do vaccines prevent disease — even among people too young to get vaccinated? It's a concept called 'herd immunity,' and it relies on a critical mass of people getting their shots to break the chain of infection. Health researcher Romina Libster shows how herd immunity contained a deadly outbreak of H1N1 in her hometown." – Source: TED
