Check-in staff at hotels and airports, shop assistants, baggage handlers and taxi drivers are among those with the biggest risk of contracting Covid, new data reveals. A survey of vaccination rates for key Australian industries has identified workers on the frontline who are most likely to be under 40 and not had any Covid jab yet. Around three-quarters of food and accommodation staff are under 40, as are almost two-thirds of store workers and four out ten taxi drivers. But just one in 10 Australians under 40 has been able to get fully vaccinated, leaving 90 per cent at potentially increased risk of contracting and spreading the disease.
