AstraZeneca`s antibody fails in protecting exposed patients from COVID-19

The KDCA said a total of 10 million doses of vaccines from four pharmaceutical firms -AstraZeneca, Pfizer, Moderna and Johnson & Johnson's Janssen - are scheduled to arrive in the country in July. Health minister Greg Hunt described the decision on Thursday as conservative and reflecting the relatively low risk of catching the virus in Australia.

"Are we on track to offer every Australian a vaccine, who is eligible, during the course of 2021?"

He said the government would move immediately to open Pfizer vaccines to anyone aged between 40 and 59.

"So people over 60 should still be rolling up to their GP and get that first dose".

"I would strongly encourage everyone to get that full protection".

"Anyone who has had a first dose of AstraZeneca without problem should feel very confident to have their second dose", Professor Kelly said.

"Vaccinating general members of the population kicks off in full-scale in the third quarter", KDCA chief Jeong Eun-kyeong said, urging people to receive vaccines during their designated period to help the country achieve the goal of herd immunity by November.

"For most people, they've been diagnosed early, there was a large proportion of those with a less severe form of this of this rare syndrome, and most of those have been discharged from hospital already".

The KDCA said while many studies are ongoing globally, there is no safety issue and some studies even suggest such a mix and match schedule may create higher antibody levels than two doses of a single vaccine. There are now a total 37 confirmed and 23 probable cases of TTS in Australia. "Cases overseas have been reported at all ages". These cases concerned women aged 55 and 65, and probable cases of another 69-year-old as well as 50 and 56-year-old men from Victoria, and a confirmed case of a 53-year-old woman from NSW and a probably case of a 67-year-old woman from the same state.

The KDCA said it will also allow combining AstraZeneca and Pfizer vaccines in two-shot regimens among some groups starting next month to boost efficacy.

"Australia does not have enough back up options and now we're paying the price with not enough supply".

Australia has only a few locally transmitted cases of Covid-19 and has closed its borders to all but a handful of foreign travellers.

More than 6.2 million doses have been administered nationwide since the rollout started in February.
