Query: No flu this year!!

My family and I work with the public everyday and we have been using oscillococcinum since the flu outbreak of 2012/2013. With all the hacking, sniffling, and body aches coming through our door, we are convinced that our healthy habits and this product aided us in keeping our immune system working to fight-off all the germs coming our way! I will purchase again and recommend others do as well.
