What price protects health? How cost shapes PrEP use among gay and bisexual men

A new study asked 612 gay and bisexual men in New England how much they’d pay each month for PrEP, the daily pill that cuts HIV risk by over 90 %. Instead of giving them a fixed price, researchers showed different monthly costs—from free up to $105—and watched how willingness to pay changed. Every extra $10 on the bill dropped willingness by 6 %. A $1 increase shrank the odds of saying “yes” by 4 %. At $40 a month, two-thirds still said they’d pay, but below $20, almost everyone was on board.Money mattered most to people earning less than $75, 000 a year. For them, each $10 jump cut willingness by 8 %, twice as much as for higher earners. That makes sense: a $40 pill eats a bigger share of a smaller paycheck. Meanwhile, guys who felt they were at real risk of catching HIV were more ready to open their wallets. Those who believed they definitely needed PrEP were also more likely to pay. Overall, the study shows that even small fees scare people away. If the goal is to get PrEP into more hands, the simplest fix may be to make it free—or at least keep the price near zero.
