AstraZeneca admits its Covid vaccine can cause rare side effect in court documents for first time

Pharmaceutical giant being sued in class action over claims its vaccine caused death and serious injury in dozens of cases

AstraZeneca has admitted for the first time in court documents that its Covid vaccine can cause a rare side effect, in an apparent about-turn that could pave the way for a multi-million pound legal payout.

The pharmaceutical giant is being sued in a class action over claims that its vaccine, developed with the University of Oxford, caused death and serious injury in dozens of cases.

Lawyers argue the vaccine produced a side effect which has had a devastating effect on a small number of families.

AstraZeneca is contesting the claims but has accepted, in a legal document submitted to the High Court in February, that its Covid vaccine “can, in very rare cases, cause TTS”.

In a letter of response sent in May 2023, AstraZeneca told lawyers for Mr Scott that “we do not accept that TTS is caused by the vaccine at a generic level”.

But in the legal document submitted to the High Court in February, AstraZeneca said: “It is admitted that the AZ vaccine can, in very rare cases, cause TTS. The causal mechanism is not known. 

“Further, TTS can also occur in the absence of the AZ vaccine (or any vaccine). Causation in any individual case will be a matter for expert evidence.”

Lawyers argue that the AstraZeneca-Oxford vaccine is “defective” and that its efficacy has been “vastly overstated” – claims AstraZeneca strongly denies.

Scientists first identified a link between the vaccine and a new illness called vaccine-induced immune thrombocytopenia and thrombosis (VITT) as early as March 2021, shortly after the Covid-19 vaccine rollout began.

Lawyers for the claimants argue that VITT is a subset of TTS, although AstraZeneca does not appear to recognise the term.

In a statement AstraZeneca said: “Our sympathy goes out to anyone who has lost loved ones or reported health problems. Patient safety is our highest priority, and regulatory authorities have clear and stringent standards to ensure the safe use of all medicines, including vaccines.

“From the body of evidence in clinical trials and real-world data, the AstraZeneca-Oxford vaccine has continuously been shown to have an acceptable safety profile and regulators around the world consistently state that the benefits of vaccination outweigh the risks of extremely rare potential side effects.”

The company is pointing out that product information relating to the vaccine was updated in April 2021, with the approval of the UK regulator, to include “the possibility that the AstraZeneca-Oxford vaccine is capable, in very rare cases, of being a trigger for” TTS. 

The company does not recognise claims it has performed an about-turn in acknowledging that the vaccine can cause TTS in court documents.
