I avoid all vaccines, They use an aluminum compound as an adjuvant to aggravate the immune system. Aluminum is not good from a weak brain much less any brain. My supplement regimen has kept me free of colds and flu for at least 15 years. If I get a cold, it lasts a few days max of sinus congestion. I also use a Chloraseptic type of spray on my throat before going to bed and a saline nose spray to help clear my sinuses.

A study done some time ago showed an increase in Alzheimer's like symptoms for seniors who have had a history of repeated flu shots.

Maybe the skin prick flu shot or nasal spray flu vaccine has less of the aluminum.

Not for me.
