[2011 May] UK Government Documents on Aluminium in Vaccines by John Heptonstall  It has been found that Calcium Gluconate solution in glass vials contains almost 200 times more aluminium than Calcium Gluconate in plastic vials; this is due to the solution leeching aluminium from the glass.....Many vaccines are packaged, and stored for long periods, in glass vials with rubber stoppers, and aluminium is a commonly used adjuvant at specific concentrations, the MHRA findings suggest that these concentrations of aluminium may have been heavily contaminated by leeched aluminium at levels which should cause concern.      
....Meningitec manufactured by Wyeth is also stored in glass vials. The recently hyped H1N1 vaccine issued in millions of doses prepared in glass vials each containing 10 individual patient doses; in Chicago alone more than 100,000 persons were inoculated with that vaccine; will Chicago experience an associated increase in mental deterioration as neurological effects take hold amongst that vaccinated group?
