BRISBANE, Australia (AP) — Australian swimmer Cate Campbell has incorporated something new into her fine-tuning as she prepares for a fourth Olympics. The two-time Olympic gold medalist lined up among the first of Australia’s athletes to get her first shot of a vaccine for COVID-19. The 28-year-old Campbell says “We’re going into a pretty unknown situation over in Tokyo so to have this little (injection ) is a huge weight off everyone’s shoulders.” Australia’s national vaccination rollout is behind schedule and Olympic participants needed to get special government approval to access vaccines this month.
