Circadian misalignment refers to the body''s own natural biological clock which regulates when we want to sleep, eat and wake, reports The Telegraph.

Washington, March 3 : Scripps research scientists say that a new vaccination method they have developed may be used to provide instantaneous protection against diseases caused by viruses and bacteria, cancers, and even virulent toxins.

Professor Carlos Barbas, III, says that tests on mice suggest that the vaccination method called covalent immunization can overcome a major drawback of vaccinations - the lag time of days, or even weeks, that it normally takes for immunity to build against a pathogen.

He revealed that his team tested the vaccination method on mice with either melanoma or colon cancer.
