In a San Diego hospital, a therapy dog Ollie sits besides children as they get vaccinated for COVID-19 vaccinations. The fluffy, white goldendoodle comforts children as he helps them overcome their fear of needles. "In a couple cases, Ollie could sit right next to them and they didn't need to be held," said Kristin Gist, the owner of Ollie. "They were distracted by fluff next to them."
