Just seven injections of vaccines or the aluminum salt added to vaccines caused alarming behavioral changes linked to a fatal nervous system disorder in sheep, a new study from Spanish veterinary researchers shows.
Vaccinated lambs and lambs that received injections of aluminum that is used in human vaccines as well, began aggressively biting the wool from other sheep, pacing restlessly and overeating, according to the study published this week in the journal Pharmacological Research.
