Without access to other photos of Tiffany Dover without her face mask covering, it's hard to tell whether the sidebar image is her or not. I did embed the captioned photo of Ms. Dover because it contained a copyright label:

Whose bright idea was that? Nurse who faints when she feels pain is chosen to get Pfizer's vaccine live on air… and collapses moments after the jab

Tiffany Pontes Dover, a 30-year-old mother-of-two and nurse manager at CHI Memorial Hospital in Chattanooga, Tennessee, was among the first staff members there to receive the vaccine on Thursday.

But 17 minutes after getting the vaccine, she was speaking to local news outlet News Channel 9 when she suddenly started feeling unwell...

Her colleagues insisted it had nothing to do with the vaccine.

Dover said afterwards that she felt fine and that she wasn't surprised because it's 'normal' for her to faint after getting an injection

'It is a reaction that can happen very frequently with any vaccine or shot,' said Dr. Jesse Tucker, Medical Director of critical care medicine at CHI Memorial, who also received the vaccine.

They did not explain why she was chosen to go on TV to get the injection if she knew she was prone to fainting.

The condition is known as Vasovagal Syncope.

It is the most common cause of fainting and triggers include pain, the sight of needles, intense heat, standing for too long and dehydration.

Despite her going back on camera after collapsing to insist she was 'fine' and explain she had the condition, videos of Dover fainting went viral.
