Vaccines will not cause chemicals to be present in the eggs. The vaccine should leave NO chemical trace in the chicken after 48 hours or so. The vaccines themselves are not chemically based--at least in the way you are thinking--and the solution they are suspended in is (basically) salt water.

Whaaaaaat??? They put formaldehyde in human vaccines, but saline in the ones for poultry? There is something so not right about that. Next you are going to tell me that none of the chicken vax were developed on the cell lines of aborted babies like some of the human ones. I mean chicken pox was developed on an aborted baby, so chicken vax would be too, right? JK. Oh well, thanks for the info. Now I need to figure out how to vaccinate. I hate to buy 1,000 doses for 16 chickens.
You are both correct, and you are both incorrect. Different vaccines are developed differently. I cannot verify it, but would be surprised if human embryos were used for animal vaccinations. The purpose is to have the vaccine work on the target species.
Likewise, the preservatives for all vaccines vary. Not all human vaccines use formaldehyde. (And slightly off topic, but do you have any idea how most olives are processed?)
Man, but not all vaccines shed the virus for up to 30-50 days. Most poultry shows and some states specifically have rules against exhibiting poultry that have been vaccinted in the past month or two.
Most vaccines were developed because the illness they prevent are so devastating. In a world where most people are vaccinated, we really have no clue how much of a blessing many vaccines are. That said, I do not believe that all vaccines currently available or recommended are against devastating illnesses.
