Hep A vaccine can last up to 25 years. Maybe you are still covered???
Ask your health provider for a copy of the manufacturers ingredient list before you take the shot.
The whole cell pertussis vaccine (DPT), which is not used in the U.S. anymore but is still used in other countries, contains whole B. pertussis bacteria that have been inactivated with heat and chemicals, as well as an aluminum adjuvant and mercury preservative (thimerosal). The purified DTaP/Tdap vaccines packaged in single dose vials given to American babies since the late 1990’s, contain reduced bioactive pertussis toxin, less endotoxin and either no or reduced (trace amounts) of mercury, along with an aluminum adjuvant.
Depending upon the vaccine manufacturer, shots containing pertussis vaccine may contain varying amounts of inactivated pertussis toxin, filamentous hemagglutinin (FDA), pertactin, fimbriae, formaldehyde, polysorbate 80 (Tween 80), gluteraldehyde, 2-phenoxoyethanol, aluminum and thimerosal (mercury).
Other ingredients are included in larger combination shots that bundle pertussis, tetanus and diphtheria vaccines with polio, hepatitis B and/or HIB vaccines.
