Twitter later said the account had been locked in error and reinstated it.
According to a Twitter spokesman, the platform took enforcement action on the National File's account in error. That action has been reversed and the account has been reinstated.
The National File's report was about Twitter user Tami Burages, who said her teenage nephew had died shortly after receiving a second dose of the Pfizer vaccine.
"Our family is devastated," said Burages "I struggled with putting this out on twitter. I am pro-vaccine. We vaccinated my own 14-year-old son as soon as it was available. I know it is *mostly safe*. But Jacob is dead now."
"I do believe that the vaccine is saving millions of lives," continued Burages subsequent tweets. "But should any innocent child be a sacrificial lamb in this endeavor? There are moral, ethical and health questions that need to be answered. If Jacob had not received the 2nd shot, we believe he would be alive today."
