A petition calling for young people to be given leftover coronavirus vaccinations has gained thousands of signatures, as under 40s chase unused doses of AstraZeneca jabs. The plea has been launched by Melbourne woman Sarah Moran, 36, who also wants the government to reveal just when it plans to officially rollout vaccinations to that age group. She turned up at the city's Royal Exhibition Buildings and "begged" for a dose of AstraZeneca, which is being reserved for over 50s because of the rare risk of blood clots, two weeks ago. Young people in Sydney are also managing to get appointments for unused jabs.
