Hi Kirt and Melissa and Jaloa, Congratulations! Please forget about that polio vaccine. Formaldehyde is one of the ingredients and the only cases of polio found lately were caused by the vaccine. Vaccines are found to destroy immune systems. A cash cow for the medical industry is how vaccinations figure in the scheme of things and population control! No one knows how many brain damaged children and deaths have resulted from vaccinations! But the figure is HIGH! All the best, Susan
