This is what I found on RabAvert. I don't see any mercury and such. I might have missed it but I didn't see anything.

DESCRIPTION
RabAvert® (Rabies Vaccine) produced by Novartis Vaccines and Diagnostics GmbH & Co. KG is a sterile
freeze-dried vaccine obtained by growing the fixed-virus strain Flury LEP in primary cultures of chicken
fibroblasts. The strain Flury LEP was obtained from American Type Culture Collection as the 59th egg
passage. The growth medium for propagation of the virus is a synthetic cell culture medium with the addition
of human albumin, polygeline (processed bovine gelatin) and antibiotics.
The virus is inactivated with ß-propiolactone, and further processed by zonal centrifugation in a sucrose
density-gradient. The vaccine is lyophilized after addition of a stabilizer solution which consists of buffered
polygeline and potassium glutamate.
One dose of reconstituted vaccine contains less than 12 mg polygeline (processed bovine gelatin), less
than 0.3 mg human serum albumin, 1 mg potassium glutamate and 0.3 mg sodium EDTA. Small quantities
of bovine serum are used in the cell culture process. Bovine components originate only from source countries
known to be free of bovine spongiform encephalopathy. Minimal amounts of chicken protein may be present
in the final product; ovalbumin content is less than 3 ng/dose (1 mL), based on ELISA. In the final vaccine,
neomycin is present at < 1 ?g, chlortetracycline at < 20 ng, and amphotericin B at < 2 ng per dose.
RabAvert® is intended for intramuscular (IM) injection. The vaccine contains no preservative and should be
used immediately after reconstitution with the supplied Sterile Diluent for RabAvert® (Water for Injection).
The potency of the final product is determined by the US National Institute of Health (NIH) mouse potency
test using the US reference standard. The potency of one dose (1.0 mL) RabAvert® is at least 2.5 IU of
rabies antigen.
RabAvert® is a white, freeze-dried vaccine for reconstitution with the water for injection diluent prior to use;
the reconstituted vaccine is a clear to slightly opaque, colorless solution.
