Publication number: 20210048247Abstract: Methods for preparing dried pellets of biological materials are described. The pellets can have a substantially spherical shape and are prepared by freezing droplets of a liquid composition of a desired biological material on a solid surface followed by microwave vacuum drying the frozen droplets. These methods are useful for preparing dried pellets having a high concentration of a desired biological material, in particular a therapeutic protein or vaccine, and which have a faster reconstitution time than lyophilized powder cakes prepared in vials.Type: ApplicationFiled: October 27, 2020Publication date: February 18, 2021Applicant: Merck Sharp & Dohme Corp.Inventors: Akhilesh Bhambhani, Robert K.

Patent number: 10350289Abstract: The present invention relates to a method of vaccinating a patient against varicella zoster virus (VZV) by delivery of an effective amount of a live attenuated VZV vaccine to the epidermis or the dermis of a patient's skin at a depth of between about 100 and about 700 microns from the surface of the skin, which is useful for preventing herpes zoster or reducing the severity or duration thereof. In embodiments of the invention, the patient is 50 years of age or older and has been previously exposed to VZV. The invention also relates to a method of preventing VZV infection in an individual who was not previously infected with VZV comprising administering an effective amount of a live attenuated VZV vaccine to the epidermis or the dermis of the individual's skin at a depth of between about 100 and about 700 microns from the surface of the skin.Type: GrantFiled: September 2, 2014Date of Patent: July 16, 2019Assignee: Merck Sharp & Dohme Corp.Inventors: Brian K.
