Infanrix is the 3 in 1 just for Diptheria, Tetanus and Whooping Cough.
There is also Infanrix-IPV This is a 4 in 1 for diptheria, tetanus, whooping cough and polio.
Infanrix-IPV+Hib is a 5 in 1 vaccine against diphtheria, tetanus, whooping cough, polio and Hib infection aswell.
Pediacel is the 5 in 1. It's patient information leaflet can be found on here It's for diptheria, tetanus, whooping cough, polio and Hib.
Pediarix is another 5 in 1. This one is for diptheria, tetanus, whooping cough, polio and hepatitis B. It does not contain thimerosal as a preservative. Thimerosal is used during the early stages of production, and subsequently removed, leaving only a clinically insignificant trace.
This is it's patient information leaflet.
Pentacel This one is also for diptheria, tetanus, whooping cough, polio and hib.
All of the above vaccines contain aluminium and traces of formaldehyde which both have similar concerns to thimerosal. When they say traces they say it is clinically insignificant however they mention if you are allergic to formaldehyde not to have it
Slight contradiction there!
