At the start of the COVID-19 pandemic, Machouf encouraged young people to get the vaccine, saying "while younger adults are less likely to get seriously ill from COVID-19, it’s important that they get vaccinated in order to prevent the transmission of the virus, especially because they tend to have a lot of contacts."
