Millions of people in dozens of countries have received the AstraZeneca Covid-19 vaccine with few reports of ill effects.

A "vaccine-induced brain haemorrhage" was listed in his post-mortem as a contributing factor to his "unnatural" death, according to assistant coroner Dr Julian Morris.

The primary cause of death was registered as brain stem herniation, which occurs when brain tissue, blood, and spinal fluid shifts from its normal position inside the skull.

Bleeding, also called haemorrhage, is the name used to describe blood loss.

It can refer to blood loss inside the body, called internal bleeding, or to blood loss outside of the body, called external bleeding.

One study published in the National Library of Health investigated fatal cerebral haemorrhage from the COVID-19 vaccine.
