Nova Scotia health officials are urging people to be cautious about some anti-flu vaccine literature being distributed by a chiropractor in Clayton Park.

The Capital District Health Authority recommends people get flu shots every year. Children under the age of five need it especially because they are in a high-risk category, according to the health authority.

However, some literature available at the Genesis Chiropractic and Wellness Centre on Lacewood Drive suggests flu shots increase the risk of a child ending up in hospital. The literature also links Alzheimer's disease to flu shots.

No one from the clinic returned calls from CBC News on Monday.

Brad Lohrenz, the chair of the Nova Scotia College of Chiropractors, said the author of the pamphlet did his homework.

"Chiropractic is really pro information. Look at the positive, look at the negative, look at both sides, get your information and make the appropriate decision that's right for you," he said.

Dr. Robert Strang, Nova Scotia's chief public health officer, said the message is wrong. He said the pamphlet is not based on medicine and is confusing to the public.

"It's discouraging, but unfortunately there are a range of what I call alternative-medicine practitioners who espouse a whole bunch of views which aren't evidence based," he said.

Nova Scotia's flu shot campaign began on Monday.
