Sunrise host Natalie Barr made a disturbing reveal while receiving her Covid vaccination live on air about misleading comments she has copped on Instagram.
Barr and her co-host David Koch received the jab during the program on Thursday and discussed some of the questions surrounding it with GP Ginni Mansberg.
The TV host said she was shocked by some of the confronting feedback she received ahead of the vaccination.
The pair received the AstraZeneca vaccine as they are eligible under phase 2a for all adults over 50 years of age.
The GP said on the program the first jab had an 81 per cent efficacy against most strains while the second dose boosted it to 86 per cent.
In the first myth debunked, Barr asked the GP whether or not moving your arm around following a vaccination would make it hurt less.
The GP said shaking your arm had no impact before answering questions about possible side effects.
She said people can expect to feel feverish, a bit tired, or a develop a headache.
"About 80 per cent have a side effect, even if it is just a sore arm," Dr Mansberg said.
"There are reasonably high rates of side effects, but that's also how you know that is is working."
Barr called an 'idiot' on Instagram for getting jab
Barr then told the GP she had received disturbing feedback from people on her Instagram account, with some saying the vaccination had not been tested and she was an "idiot" for getting the jab.
Dr Mansberg quickly refuted claims the vaccination hadn't been tested for use in Australia.
"The Australian Therapeutic Goods Administration is possibly the best and most rigorous standard of evaluating drugs and vaccines in the world, but it has also been evaluated by the World Health Organisation, European Medicines Agency and the UK," she said.
"We have reasonably good data because there was so much Covid around when we were doing the initial studies.
"The numbers were big. If you have a mumps vaccine you need to wait until you have enough mumps cases to test it but in the case of Covid there were so many cases around, sadly, that we got to those numbers very quickly."
Monitoring for vaccine side-effects
Dr Mansberg said people who received the jab would be monitored by their GP for 15 minutes to ensure there is no rare case of an allergic reaction.
"We have not seen [an allergy] but that is a theoretical thing, and some people just feel quite faint. Getting needles is quite stressful for a lot of people."
Koch then addressed another conspiracy theory the vaccination contained microchips or tracking technology.
"No, that is just bizarre," Dr Mansberg said.
The Department of Health also wrote on its website that none of the Covid-19 vaccinations contained software or microchips and could not be used to track people.
It added the vaccines had met the Therapeutic Goods Administration's rigorous standards for safety, quality and efficacy.
