INTRODUCTION: This is an update from our earlier report (Part II) regarding the use of the SARS-CoV-2 spike protein with two different adjuvants. The Phase I clinical trial results were presented in The Lancet by Richmond et al1. This was the first human trial of this subunit vaccine and was used to find the proper […]
INTRODUCTION: Shingles, or herpes zoster (HZ), is an acute, viral infection that occurs after the reactivation of the varicella-zoster virus (VZV). The virus usually remains dormant within dorsal root ganglia after the virus’s primary infection presentation in the form of varicella. HZ is thought to appear when the immune system is under stress due to […]
INTRODUCTION: In the last several years, a new approach to viral vaccine design has shown great promise. Vaccine makers are looking to see if the success can be replicated with other vaccines. Shingles is a viral infection that is caused by reactivation of varicella zoster virus (VZV), causing chickenpox upon primary exposure. The incidence of […]
INTRODUCTION: In this follow-up report, we discuss several adjuvanted SARS-CoV-2 subunit vaccines in development. In general, subunit vaccines exhibit low immunogenicity and require assistance from an adjuvant to enhance a robust vaccine-induced immune response. The S glycoprotein of SARS-CoV-2 is the preferred viral protein to induce neutralizing antibodies due to its known immunogenic properties. The […]
INTRODUCTION: Over the last several decades, subunit vaccines have shown consideration for vaccines. About 30 years ago, scientists developed a potential subunit vaccine for the varicella-zoster virus (VZV).1 A subunit vaccine’s advantage is several-fold, including not needing to grow and inactivate live viruses (or create an attenuated virus strain) and use the most antigenic portion […]
INTRODUCTION Herpes zoster (HZ) is caused by reactivation of latent varicella-zoster virus (VZV) within the cranial nerve or dorsal root ganglia after primary infection. There is a lifetime risk, ~10% to 30%, of HZ in adults, but is rare in healthy children. Immunocompromised individuals have an increased risk of other diseases, including HZ. Risk of […]
INTRODUCTION: In the first nine months of 2020, it is becoming increasingly clear that being infected with the severe acute respiratory syndrome Coronavirus 2 (SARSCoV-2), now commonly referred to as COVID-19, may lead to the reactivation of varicella-zoster virus (VZV), causing herpes zoster (HZ).
