One of the first people to trial the new coronavirus vaccine has listed some of the concerning side effects.

Speaking to Piers Morgan and Susanna Reid on Good Morning Britain this morning, novelist and former kid's TV presenter Simeon Courtie explained why he volunteered to trial the vaccine and revealed some of the potential side effects, the Mirror Online reports.

Human trials for the vaccine in the UK are set to get underway today at the University of Oxford.

Watch the video above to see what Simeon had to say.

The side effects to the vaccine can include flu-like symptoms, aches and pains, and at worst a fever for several days, Simeon revealed.

"It shouldn't be too disruptive," he added.

Simeon explained that he is one of 500 people assisting with the trial in Oxford, and he called himself "just a very small part of this thing".

He added: "We are the safety part of this process to see if it's safe, and after my trial there will be an efficacy trial in the community to see if it works on thousands of people."

Susanna Reid asked Simeon if there was a control group, and Simeon replied that there was not.

There are two groups in the trial, one is receiving the new vaccine for the coronavirus, and the other is receiving the vaccine for meningitis, and they would not be told which group they were in, because both vaccines cause similar side effects.

Piers Morgan thanked Simeon for his bravery and stepping forward to help out in the time of crisis.

Simeon also answered some questions on social media about the human trials.

Simon explained on Twitter: "Nope. In fact that excludes people. Volunteers are screened and need to be healthy".

He also tweeted: "Very happy to be invited onto @GMB with @susannareid100 and @piersmorgan today to talk about volunteering on the Oxford Vaccine Trial which starts today. Good luck to the amazing scientists at @JennerInstitute ".

Good Morning Britain airs weekdays from 6am on ITV.
