Several Norwegian scientists have warned that this modern practice of vaccinating healthy people against flu actually wide opens the door for a future "Spanish flu" pandemic, rather than closes that door.
The scientist have the right idea about Flu Shots making the populace susceptible to other flu viruses. Canadian scientist in 2009 published a study in the Science Translational Medicine.
Dr. Danuta Skowronski, a flu expert at the B.C. Centre for Disease Control in Vancouver, spotted a surprising and unsettling trend when she looked at data on people in British Columbia who contracted H1N1 in the spring and summer of 2009. People who had received a seasonal flu shot the previous autumn were more likely to contract the new pandemic strain.
Her findings, which were initially dismissed by many in the global influenza research community, were later replicated in studies done in other provinces as well, leading some to dub the phenomenon “the Canadian problem.”
