Monkeypox Coverage:
In Africa, monkeypox infections in children have been more common, and doctors have noted higher proportions of severe cases and deaths in young children.
One reason may be that many older adults were vaccinated against smallpox as kids, likely giving them some protection against monkeypox, said Dr. James Lawler, an infectious disease doctor at the University of Nebraska Medical Center.
Smallpox vaccinations were discontinued when the disease was eradicated about 40 years ago. So, children since then have not been vaccinated against smallpox and wouldn't have any such protection against the related monkeypox virus, Lawler said.
