Course Description

This course will introduce the attendee to the historical development of vaccines, the different types (classes) of vaccines in use today, and will orient the attendee to the laws (PHSA, FD&CA) and regulations (ICH, FDA Guidance’s) required for vaccine development and commercialization. The separate roles of FDA and CDC in the US will be discussed, and the regulatory pathways for marketing authorization (MAA) of vaccines in the EU will be presented.

 

The basic bioprocess steps to produce bacterial and viral vaccines will be discussed with a focus on global regulatory guidance (ICH) and FDA Guidelines of importance. Requirements imposed on vaccine CMC development and commercialization by the Public Health Service Act (PHSA) and the Food, Drug and Cosmetic Act (FD&CA) will be discussed. Quality control strategies for classes of vaccines will be presented. 

 

An overview of the elements of the immune system will be presented and factors affecting the immune response to vaccines will be discussed. Immunological assays applied to certain vaccines in the measurement of quantity and potency will be highlighted. 

 

We will conclude with an overview of therapeutic vaccine development strategies (vaccine types) regulated by CBER’s Office of Therapeutics and Advanced Therapies, followed by a more in-depth look at some vaccines developed globally to address the COVID-19 pandemic, with an examination of the unique production methods and drug product formulation requirements for the new class of mRNA vaccines and a view of the associated control testing of these products.

Who Should Attend

This 20 hour course is designed for senior management, directors, managers, supervisors, project planners and professional staff seeking to obtain a broad understanding of vaccines and the regulation/Regulatory Guidelines, CMC development and quality assurance/control of vaccines for infectious disease or therapeutic indications. Typical attendees would include Regulatory Affairs, Quality, Product/Process Development and Project Management functions and Business Decision Makers.


The course can be customized to address specific organizational, departmental, or functional issues and delivered on site.

  • Learning Objectives

    This course provides a solid foundation to understand scientific, global regulatory principles and approval strategies of Cell & Gene Therapies. It allows to coAt the end of the three-day course attendees will:

    • Gain a solid understanding of the regulatory framework for vaccines for prophylactic (infectious disease) and therapeutic indications, incidents that have prompted regulation, and an understanding of the differences and commonalities of vaccine regulation versus small molecule drugs and other biologics. 
    • Understand the structure of CBER within FDA and its historical evolution, and the processes in place in EU for review and authorization of new vaccines. 
    • Understand the fundamental bioprocess steps in production of bacterial and viral (cell-based) vaccines and control testing requirements/strategies, including a basic understanding of Master Cell Banks, Master Viral Seeds, upstream and downstream processes, and testing/characterization of process- and product-related impurities and adventitious agents.
    • Gain an understanding of the elements of the immune system and its response to vaccines, and the use of basic immunological methods used in the quality control and characterization of vaccines.
    • Gain an understanding of the different types (classes) of prophylactic vaccines in commercial use, including live attenuated vaccines, inactivated bacterial and viral vaccines, subunits/toxoids, recombinantly produced vaccines and gene-based (mRNA) vaccines, and an understanding of approaches (vaccine types) being evaluated as potential therapeutic vaccines for conditions such as cancer.  
    • Understand the rapid development of COVID-19 vaccines through government funding (OWS, BARDA) and the current FDA requirements for Emergency Use Authorization (EUA) and full approval (BLA) of COVID-19 vaccines. Gain an understanding of different approaches undertaken by companies globally to develop COVID-19 vaccines and real-word safety experience, and understand the quality control strategies applied to these vaccines.

  • Agenda


    Historical Development of Vaccines

    • From smallpox vaccination to today’s new mRNA vaccines for COVID-19
    • Classes of vaccines (live attenuated, inactivated bacteria and viruses, toxoids and subunit vaccines, recombinant proteins/viruses, gene-based vaccines)
    • High level view of vaccines in commercial distribution today
    • Progression of vaccines recommended for routine use: 4 pediatric vaccines (1940s) to 15 vaccines today.

    Development of Vaccine Regulation

    • Early regulation of vaccines/biologics in the US – a horse named Jim 
    • Regulations evolve in parallel with traditional drugs: The Public Service Health Act (PHSA) and the Food Drug and Cosmetic Act (FD&CA)
    • The “Cutter Incident” and other disasters spur regulation
    • Vaccine regulatory authority moves from NIH to FDA; more than just an administrative shift
    • What is a vaccine, anyway?
    • Current organization of CBER within FDA; Office of Vaccines Research and Review, Office of Tissues and Advanced Therapies 
    • MAA pathways in EU for vaccines (Centralized Procedure, Decentralized and Mutual Recognition procedures)

    Immunization policy in the US and EU

    • Roles of CDC and ACIP, and FDA and VRBPAC in the US
    • Decentralized vaccination policy within the EU (vaccines used, routes of administration, vaccination schedules)

    Vaccine Production Overview – Basic Production Processes for Bacterial and Viral Vaccines 

    • Fundamental process steps for vaccine production
    • Upstream and downstream vaccine production processes – a high level view 
    • Examples of manufacturing process flows for a bacterial conjugate vaccine and an inactivated influenza vaccine
    • Master Cell Banks and Master Virus Banks for vaccine production; ICH Q5B and Q5D, FDA Guidance on Viral Vaccines
    • Cell substrates used to produce licensed vaccines
    • Vaccine purity/impurities:  process related impurities, product related impurities and adventitious agents; regulatory and quality considerations; ICH Q5A    

    Vaccine Production Overview – Basic Production Processes for Bacterial and Viral Vaccines - continued
