The sales of Shingrix, the shingles vaccine, are indeed tied to the aging population (those reaching 50 years old) and the willingness of people to get vaccinated. Given that the vaccine is targeted at adults over 50, the growth rate will naturally slow as the target demographic becomes saturated over time. To sustain or increase sales, GSK will likely need to focus on expanding its reach internationally or targeting specific patient groups who may still need the vaccine, such as those who are hesitant or unaware of its benefits.
The RSV vaccine has faced some challenges, including skepticism or caution from advisory committees, which has influenced its sales potential. While GSK has made efforts to boost patient awareness, there’s an underlying question of whether RSV in adults is as significant a concern as it has been marketed to be. In the case of RSV, if adults didn't view it as a significant issue before, it might be partly due to shifts in how the pharmaceutical industry has highlighted the risks associated with the virus. Creating a bigger problem than there is creating corporate greed no public need.
While childhood vaccines remain an essential revenue driver, the success of vaccines for rarer conditions like MEN, driven by fear-based marketing strategies (dinner programs featuring amputees), is a reminder of the power—and the potential ethical risks—of how these products are marketed to healthcare providers.
