Abstract:
Description The world is in the midst of a pandemic from COVID-19, a disease caused by the virus SARS-CoV-2. Despite broad mitigation efforts, new cases continue with 74 million cases and 1.6 million deaths worldwide. Regardless of previous research efforts, there is no commercially available vaccine for any coronavirus. Novel vaccine development has historically taken at least 10 years from discovery to availability with only a 6% market entry probability. With the global impact, there is an urgency to expedite a vaccine to protect the population. The U.S. government launched Operation Warp Speed with the goal to produce and deliver 300 million doses of safe and effective vaccines by January 2021. Efforts toward this goal have included coordinated government agency support, parallel clinical trial deployment, de-risking manufacturing earlier in the development process and real-time U.S. Food & Drug Administration evaluation of the safety and efficacy data. Safety is a priority and key analysis has not been eliminated during the compressed timeframe. The two frontrunner candidates show promising efficacy rates for preventing COVID-19 with Moderna reporting 94.1% efficacy and Pfizer reporting 95.0% efficacy. Despite the herculean efforts by scientists to develop an effective vaccine in such a short timeframe, several national surveys suggest that public confidence in these vaccines is low with less than 50% of the survey respondents willing to be vaccinated. According to experts, the U.S. needs the vaccine to be at least 70-80% effective and a 70-80% vaccination rate in order to return to normal. Significant education and promotion is planned in coordination with the Centers for Disease Control.

Cancer Vaccines
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.

Conjugated Proteins
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...
