AstraZeneca and Oxford coronavirus vaccine volunteer dies from causes still under investigation

2020-10-21T18:45:57.113Z


It is not clear that there is a link between his death and the drug, one of the most advanced but whose tests are stopped in the US for another incident.


A volunteer in AstraZeneca and Oxford University's coronavirus vaccine trials died in Brazil, although

it is not yet clear whether the death is related to the drug development process.

Brazil's health surveillance agency Anvisa said in a statement that the death occurred on October 19 and that an investigation will be carried out.

So far it is unknown if the volunteer of the tests had an adverse reaction to the vaccine or if the death was due to another cause.

The person may even have been receiving a placebo, used in clinical trials to contrast the results of those who are being injected with the formula.

Bloomberg reports that a source familiar with the case says the death was not due to the vaccine itself.

"Based on national and international regulations, data on clinical trial volunteers must be kept secret due to principles of confidentiality, human dignity and protection of the participants," Anvisa said.

The Brazilian agency stressed that

the International Committee for Evaluation and Safety, which monitors vaccine studies around the world, "suggested continuing with the tests" 

in Brazil, in order to determine whether there is a link between death and the injection.

The

vaccine from AstraZeneca and the University of Oxford is one of the few that are in a very advanced stage of development

: the tests are in phase 3, which consists of injecting it into thousands of people to study adverse effects.

Some vaccines already approved for use in certain countries, such as two inoculations developed in Russia, were endorsed without having this phase of analysis.

A few weeks ago, clinical trials for AstraZeneca and Oxford were put on hold around the world when another volunteer, in studies conducted in the UK, developed transverse myelitis-like lesions, which arise when there is inflammation in the spinal cord.

The European health authority later indicated that it was safe to resume the studies, which resumed in the United Kingdom and in Brazil.

However,

in the United States the tests of that vaccine against COVID-19 continue to be paused

, although the Food and Drug Administration (FDA) has already given the go-ahead for them to restart.
