But on Thursday night Roberts turned the spotlight to the importance of vaccines in a video for Red Nose Day.

The video follows Roberts as she delivers polio and rotavirus vaccines to children in a remote area of Kenya with Bear Grylls. Roberts also talks to mothers who have lost their babies to pneumonia, another sickness that is preventable with vaccines.

In a poignant exchange, Roberts comforts a mother, Lilian, who lost her baby just a week before their meeting.

“Nicholas fell sick when he was 8 months old,” Lillian said. “We took him to the hospital for admission. He was discharged. But after three days, he became unwell again. I fed him and I placed him down. But when I came back, he’d passed away.”

“I cannot believe that my baby left me. If I had taken him for the vaccination, he would not have died,” Lillian said.

Red Nose Day, an annual fundraising campaign run by Comic Relief Inc., is a day to raise awareness about children in need around the world using the power of entertainment. It’s about ending child poverty “one nose at a time.”

Roberts was just one of the many celebrities involved in spreading the word.

The importance of vaccines cannot be underestimated. Polio is 99.9% eradicated as a result of a global eradication effort. But it is just one of many preventable illnesses.

As long as one child is infected, all children remain at risk.

Global Citizen is campaigning for more funding for polio vaccines so we can eradicate the disease once and for all. Take action now.
