Thiomersal is an organomercury compound known for its antiseptic and antifungal properties and used as an antibacterial agent in pharmaceutical products, including vaccines and other injectable biological products. In recent years, concerns about the possible link between immunization with thiomersal-containing vaccines and autism development have grown. Many case-control and cohort studies have been conducted on a number of populations, and none of them have confirmed the hypothetical relation between thiomersal and increased risk of autism spectrum disorders (ASDs) development. It is also confirmed by the fact, that since 1999, number of thiomersal-containing vaccines used worldwide is decreasing year by year, while the prevalence of ASDs cases is rising. There are no contraindications to the use of vaccines with thiomersal in infants, children and non-pregnant women. The risk of serious complications associated with the development of diseases in unvaccinated individuals far outweighs the potential risk of adverse consequences associated with immunization with thiomersal-containing vaccines.
