Side effects of the AstraZeneca vaccine can include changes to the heartbeat, shortness of breath and swelling of the lips, face or throat, according to the UK government.
From May 2021, the jab was no longer offered to adults under 40 due to a link with rare blood clots.
Research into why that happens suggests a part of the vaccine can trigger a complex chain reaction involving the immune system which results in clots developing.
The UK medicines safety regulator, the MHRA, continues to monitor the effects of the vaccine.
More than 1,300 suspected deaths due to the AZ Covid jab have so far been reported to the regulator out of more than 50 million first and second doses given out. The MHRA has always said that the benefits of any vaccines or medicines must outweigh their risks.
The UK government estimates the vaccine programme prevented more than 80,000 deaths from Covid during the first six months after it was rolled out in 2021.
According to a study in the Lancet, Covid vaccinations – many of which would have been AZ jabs – prevented 14 million deaths in 185 countries between December 2020 and December 2021.
Speaking to the BBC last year, Mrs Wright said of her husband: “Being in the profession he was in, I truly believe that if he had been told all of the possible reactions, he would have still taken it [the vaccine] because I am aware it is a rare situation.”
