French pharmaceutical company Sanofi-Aventis said Monday that it was sending experts to Israel to study the deaths of four people who had recently received flu shots.
Sanofi-Aventis said its team in Israel would try to find out more about the people who died. The four people, who were elderly and suffered from chronic illnesses, had received flu shots up to six days before their deaths, company spokesman Alain Bernal said.
"We are taking this seriously, we are studying it seriously, but we have total confidence in the quality of our product," Bernal said. "This is a vaccine that saves thousands of lives every year."
