Put another way, there is no right under the FMLA âto be left aloneâ or be allowed to skirt the employerâs âdiscrete inquiries.â But if looks like work, itâs gonna be work, and an employee shouldnât be doing work while on FMLA leave.
Adjuvants are agents or drugs that have few or no antigenic effects or properties but may have the potential to increase the efficacy or potency of vaccines or other drugs when given at the same time (see Chapter 9). Some of the most common adjuvants used in vaccine preparations are aluminum salts and monophosphoryl lipid (MPL)/QS21 cocktails. The response to potential pandemic flu vaccines has been shown to be much improved by the addition of MF59 (Nicholson et al., 2001; Stephenson et al., 2003; Atmar et al., 2006; Bresson et al., 2006; Baldo et al., 2007).
Prior to licensure, as part of FDAâs evaluation, FDA takes all of the ingredients of a vaccine into account, including the active ingredients as well as other substances. After FDA approves a vaccine, FDA continuously monitors its safety. Why is aluminum in some vaccines? Aluminum salts are incorporated into some vaccine formulations as an adjuvant. An adjuvant is a substance added to some vaccines to enhance the immune response of vaccinated individuals. The aluminum salts in some U.S. licensed vaccines are aluminum hydroxide, aluminum phosphate, alum (potassium aluminum sulfate), or mixed aluminum salts.
