A few weeks ago, I drove up to a Rite Aid pharmacy near my home in San Diego and saw large red signs affixed to lampposts that urged me in English and Spanish to get my flu shot today. “FLU SHOTS NOW AVAILABLE!” blared another sign taped to the glass entrance. “No appointment necessary. Free with most insurance.” Inside the store, flu vaccine tables were set up in two different locations with one-page forms to fill out and hand to the pharmacist. A pamphlet on the table yelled, “GET YOUR FLU SHOT TODAY.” Everywhere I turned, there was another banner or poster pleading with customers to roll up their sleeves and take the shot: “Because 63% of your friends didn’t;” “Because 39% of people don’t wash their hands after they sneeze;” “Because you can catch it from someone six feet away.”
