Definitely true, but if the vitamin deficiencies hadn’t shown up yet in children the repair couldn’t have an affect. So it caps the onset time at the age of the children involved, and shows that repairs can occur after some significant effect of deficiency occurs.
Also, vitamins deficiency might set in at different times for adults and children. Children grow a lot, so their nutritional needs are probably different from adults.
