Australia has not banned the AstraZeneca vaccine, despite claims from anti-vaccine campaigners and social media users. The AstraZeneca vaccine was the only vaccine available in large amounts in Australia because the local biotech company CSL manufactures it. However, the Australian government failed to prioritize deals with other vaccine manufacturers, and the AstraZeneca vaccine was only available by request from October 2021 onwards. The Australian Department of Health and Aged Care confirmed that the vaccine was phased out due to the availability of newer options, and not because of safety concerns. The vaccine has been linked to a rare but serious side effect called thrombosis with thrombocytopenia syndrome (TTS), which involves blood clotting combined with low platelets. AstraZeneca has admitted in court documents that its Covid-19 vaccine may, in rare cases, cause TTS.

What You'll Learn
Australia did not ban the AstraZeneca vaccine
Australia did not ban the AstraZeneca Vaxzevria COVID-19 vaccine. On the Australian Department of Health's website, it states that from Monday, 20 March 2023, Vaxzevria (AstraZeneca) is no longer available. However, it does not mention that the vaccine has been banned due to safety concerns. Instead, it was phased out like an old car model being replaced by a newer and better model. The removal of the vaccine was expected as it had been superseded by other vaccines, such as Novavax, which is a more traditional-style vaccine that has been proven to be safe and effective.
The Australian government's decision to stop using the AstraZeneca vaccine was influenced by the availability of newer and better vaccines, as well as the shifting official advice on the vaccine, which fuelled hesitancy among Australians. The AstraZeneca vaccine was once the only vaccine available in large amounts in Australia because it was manufactured locally by CSL. However, under advice from the Australian Technical Advisory Group on Immunisation (ATAGI), it is not the preferred vaccine for people under 60, and most Australians, including those over 60, are now waiting for the Pfizer vaccine.
The reputation of the AstraZeneca vaccine has been wrongly tarnished due to the ATAGI advice, which has been influenced by Australia's low COVID infection rate. The advice does not seem to consider the societal benefits of a rapid vaccination rollout with a safe and effective vaccine, such as the AstraZeneca vaccine. Instead, Australia is now rapidly commandeering more Pfizer doses, pushing other nations further down the vaccine queue and exacerbating global vaccine inequity.
It is important to note that the AstraZeneca vaccine is safe and highly effective, and the World Health Organization (WHO) has insisted that it is safe despite facing setbacks. The vaccine may cause rare side effects, such as thrombosis with thrombocytopenia syndrome (TTS), which involves blood clotting combined with low platelets. However, these side effects are very rare, and the benefits of vaccination far outweigh the risks.

AstraZeneca vaccine linked to rare side effects
Australia has not banned the AstraZeneca vaccine. However, the vaccine has been linked to rare side effects, and this has fuelled hesitancy in the country.
The AstraZeneca vaccine, developed in collaboration with Oxford University and manufactured by the Serum Institute of India, has been the subject of a class-action lawsuit. The lawsuit, which includes 51 cases in the UK seeking damages of up to £100 million, alleges that the vaccine has caused serious injuries and fatalities.
In court documents, AstraZeneca has admitted that its Covid-19 vaccine may, in rare cases, cause Thrombosis with Thrombocytopenia Syndrome (TTS). TTS is characterised by blood clots and low platelet counts and can prove fatal. According to the Department of Health and Aged Care, Government of Australia, TTS involves blood clotting combined with low platelets, with blood clots appearing in different parts of the body such as the brain or abdomen. The department claims there is a link between the AstraZeneca vaccine and TTS, with a higher risk in younger people.
Symptoms of TTS include severe and persistent headaches, blurred vision, confusion or seizures, weakness of the face or limbs, shortness of breath or chest pain, severe abdominal pain, leg swelling, and an unexplained pin-prick rash or bruising away from the injection site. These symptoms typically occur between 4 and 42 days after the first dose of the AstraZeneca vaccine.
Despite the rare occurrence of TTS, the emergence of this side effect has prompted regulatory scrutiny and legal action. AstraZeneca has denied claims of widespread vaccine defects or overstated efficacy, and independent studies have shown the vaccine's effectiveness in combating the pandemic. The World Health Organization (WHO) has stated that "in countries with ongoing SARS-CoV-2 transmission, the benefit of vaccination in protecting against Covid-19 far outweighs the risks".

Australia's hesitancy to use AstraZeneca
Australia has not banned the AstraZeneca Covid-19 vaccine, despite claims on social media to the contrary. From 20 March 2023, the AstraZeneca Vaxzevria vaccine was no longer available in Australia, but this was not because it was deemed unsafe. Instead, the vaccine was phased out as better alternatives became available, such as the Novavax vaccine.
The AstraZeneca vaccine was developed in collaboration with the University of Oxford and manufactured in India by the Serum Institute of India. It was once the only vaccine available in large amounts in Australia, as the local biotech company CSL manufactures it. However, the Australian government failed to prioritise deals for other vaccines, and the country's low Covid infection rate influenced the Australian Technical Advisory Group on Immunisation (ATAGI) to advise against its use for people under 60. This shifting official advice fuelled hesitancy among Australians, who increasingly viewed the vaccine as ""not good enough". As a result, Australia began to commandeer more Pfizer doses, pushing other nations further down the vaccine queue and exacerbating global vaccine inequity.
The perception of AstraZeneca as unsafe was further perpetuated by reports of serious side effects, including blood clots and fatalities. In April 2024, AstraZeneca admitted in court documents that its Covid-19 vaccine may, in rare cases, cause Thrombosis with Thrombocytopenia Syndrome (TTS). This admission came in response to a lawsuit filed by Jamie Scott, a father of two who suffered a permanent brain injury from TTS after receiving the AstraZeneca vaccine in April 2021. Several other families have also filed complaints alleging that the vaccine caused serious injuries and deaths.
Despite these reports, the World Health Organization (WHO) has insisted that the AstraZeneca vaccine is safe and effective. While some countries, including Denmark, Norway, and Thailand, have paused or banned the use of the vaccine due to concerns over blood clots, Australia continued its rollout as it found no reason to alter course.

AstraZeneca was the only vaccine available in large amounts in Australia
Australia has not banned the AstraZeneca vaccine. In fact, AstraZeneca was the only vaccine available in large quantities in Australia because the local biotech company CSL manufactures it. However, the Australian government failed to prioritise its other deals last year. The shifting official advice on AstraZeneca has fuelled hesitancy among Australians, who are now largely waiting for Pfizer.
The AstraZeneca vaccine is safe and highly effective, although almost all medicines carry some risks. The Australian Technical Advisory Group on Immunisation (ATAGI) advised that it is not the preferred vaccine for people under 60. This advice was influenced by Australia's low COVID infection rate. ATAGI's mandate is to assess risks on an individual basis, which is not entirely suitable for a pandemic affecting all of society.
The perception of AstraZeneca as unsafe has had unintended consequences for global vaccine supply, further disadvantaging those in poorer countries. Australia has come under criticism for its failure to address global vaccine inequity, especially as it has been "queue-jumping" for Pfizer doses. While Australia has donated millions of doses to countries in South-East Asia, it has also wasted millions of vaccines due to their expiration.
The COVID-19 vaccines developed by Pfizer and Moderna use mRNA technology, which is easier to scale up production for than the AstraZeneca vaccine. AstraZeneca is a DNA-based vaccine that does not need to be stored at extremely low temperatures like mRNA vaccines. However, it is less effective than the mRNA vaccines, with 62% effectiveness compared to 94% and 95% for Moderna and Pfizer, respectively.

AstraZeneca vaccine rollout paused in multiple European countries
Australia has not banned the AstraZeneca vaccine. However, the country's shifting official advice on the vaccine has fuelled hesitancy among its population. This has negatively impacted global vaccine supply, especially for poorer countries.
In March 2022, the Federal Court of Australia dismissed a case filed by an anti-vaccine group seeking to scrap the approval of the AstraZeneca, Pfizer, and Moderna vaccines. Australia continues to recommend Covid-19 vaccination for healthy children aged five and above.
Now, to address the topic of AstraZeneca vaccine rollout being paused in multiple European countries:
In March 2021, several European countries paused the rollout of the AstraZeneca vaccine due to concerns about blood clots. The chaos began when Norway and Denmark suspended the vaccine, citing reports of blood clots forming after inoculation. Denmark announced a two-week suspension of the vaccine, which was soon followed by Iceland and Norway. Austria also suspended a batch of AstraZeneca vaccines after a person was diagnosed with multiple thrombosis and died ten days post-vaccination. Another individual in the country was hospitalized with pulmonary embolism. There were also seven reported cases of cerebral blood clot formations in Germany.
The European Medicines Agency (EMA) investigated these incidents but emphasized that there might not be a link between the vaccine and the illnesses. The EMA stressed that the benefits of the vaccine in preventing COVID-19 outweighed the risks of side effects. Despite this, Germany's decision to suspend the rollout caused a domino effect, with Spain, the Netherlands, Ireland, and Italy also temporarily halting the distribution of the AstraZeneca vaccine.
The suspension of the AstraZeneca vaccine rollout in Europe was a cautious approach to ensure the safety of those being vaccinated. However, it is important to note that the number of thromboembolic events in vaccinated people was not higher than that of the general population. The challenge of distinguishing causal effects from spontaneous reports of suspected adverse reactions to a vaccine also complicates the situation.
