Alternate vaccines unlikely ‘available’ until late in the year

Infectious diseases expert Peter Collignon says the government should and does have contracts with other vaccine producers other than Pfizer and AstraZeneca, but those supplies won't be "available" until the second half of this year. “That’s why the government originally put out four different contracts”, he told Sky News host Peta Credlin. “We do have other vaccines on order in contracts – but realistically, a lot of those are not going to be available in numbers before the second half of this year."
