PIERS Morgan says his mum has had a "bad reaction" to the coronavirus vaccine.

Speaking on Good Morning Britain today, the Newick-born broadcaster said his parents had been given the jab near their home in Sussex on Saturday.

The 55-year-old said: "So my parents had the jab on 'Glorious Saturday', as it now is, with 600,000 other people.

"One per cent of the entire population of this country got vaccinated on Saturday including my parents at their local place in East Sussex.

"They said it was very efficient, very quick, very painless - all very happy.

"But my mum has then got quite a bad reaction to her jab.

"Now, I say bad, like a sort of flu-y reaction, and she is in bed."

Piers said there had been reports of "quite a few people" reacting similarly, but resident health expert Dr Hilary Jones was quick to reassure him that this was nothing to worry about.

He said: "What we do know from the trials is that most people might get a slight reaction of the injection site.

"A bit of redness, a bit sore, a bit of tenderness, some warmth and some heat.

"It will probably be a little bit sore when you move the arm and this will probably last, what, a few hours and no more.

"It will certainly be gone overnight by the next day. That is not uncommon at all. And it is common with any vaccination - whether it is flu or whatever.

"The second thing people are reporting and registering is a bit of fatigue, a headache, muscle pains - these may last a little bit longer.

"Some people are getting chills. Some people are getting a very slight temperature. Again, this can happen with other vaccinations too.

"If you are asking me about percentages, I think some reports say about 50 per cent of people will get that fatigue for a few hours - maybe 24 hours.

"It does not last longer than two or three days. Take a paracetemol or an ibuprofen - these symptoms are not anything to worry about.

""What they mean is that your body is creating an immune response. Now, that is what you want."

Dr Hilary said the side effects are common, and are often seen with other vaccines such as the flu jab and generally last for a short time.

Piers has previously spoken on the show about his parents experiences with Covid-19 on the show.

In November last year, he detailed how someone within his parents' support bubble had caught the illness, and it had spread "like dominoes".

His parents are both "in their mid-to-late 70s".

Boom, boom, boom; they had one lunch together and within three days both my mum and dad had Covid-19," he said.

"It's been a long two weeks for our family. It's long for us because we can't get in there, but incredibly long for my parents and anyone that goes through this."
