The US Centers for Disease Control and Prevention (CDC) are investigating whether a boy child’s death is directly related to vaccinations. The perfectly healthy teenager with no underlying causes died in the US state of Michigan within just three days of receiving a second dose of the Pfizer coronavirus vaccine.

13-year-old Jacob Clynick lived in Zilwaukee in Saginaw County, Michigan, US. On 13 June, he received a second dose of the Pfizer vaccine and died in his sleep three days later, according to Newsweek.

‘CDC is aware of a 13-year-old boy in Michigan who died after receiving a COVID-19 vaccination. This case is currently under investigation and until the investigation is complete, it is premature to assign a specific cause of death,’ Martha Sharan, a public affairs officer for the CDC’s COVID-19 vaccine task force said.

According to his aunt, Jacob was healthy and did not have any chronic illnesses. The woman also said that the teenager had complained of general post-vaccination symptoms for two days, fatigue and fever after taking the shots.

On 15 June, Jacob had a slight stomach ache, but not enough to raise serious concerns, aunts said. The boy fell asleep and never woke up.
