Which of the following is used as a preservative in most vaccines? Correct Answer Thimerosal
Thimerosal is a preservative used in majority of vaccines worldwide. It is a mercuric-based compound which helps in prevention of growth of bacteria or fungus. The basic principle of preservatives is to keep the vaccines away from contamination by any external or chemical factors. This preservative is so strong in its activity that it even kills the contaminant.
