INTRODUCTION

The vaccines sector is undergoing a period of growth, making it a more attractive market to pharmaceutical companies. In addition, changing population demographics, competition and new technologies are further transforming this area. Indeed, novel vaccines are anticipated to provide protection against a much wider spectrum of conditions, including infection by the major nosocomial pathogens.

SCOPE OF THE REPORT

• Overview of the current vaccine market, describing the key drivers and resistors of growth
• Descriptions of key players and new contenders in vaccines sector, detailing their current portfolios and commercial strategies
• Characterization of the clinically-significant nosocomial pathogens and information regarding the potential vaccine market size for each
• Profiles of pipeline nosocomial vaccines and an evaluation of their market potential and likely impact

REPORT HIGHLIGHTS

The growth rate for the global vaccines market currently outpaces other infectious diseases sectors with predicted year-on-year growth of 10-12%, equating to a market size of approximately $17 billion in 2010, on a par with antivirals. Datamonitor believes a large proportion of these sales will fall outside the existing four-company oligopoly.

Within the dominant high-volume pediatric segment, declining birth rates, uncertain market access and intense competition forces vaccine players to consider a range of new product strategies with a varying levels of commercial risk. Examples include monoclonal antibodies, therapeutic vaccines, newer adjuvants and delivery systems.

The niche sector of nosocomial infection vaccines has seen investment by numerous pharmaceutical companies in recent years, with many products in clinical development. Datamonitor predicts that peak global sales of an S. aureus prophylactic vaccine and therapeutic monoclonal antibody could reach $1.8 billion and $2.6 billion respectively.

KEY REASONS TO BUY THIS REPORT

• Gain insight into the current vaccine market, and identify the key players and emerging novel technologies
• Identify the companies leading the development of nosocomial vaccines and their strategies and pipeline products
• Recognize the market potential for nosocomial vaccines

CHAPTER 1 EXECUTIVE SUMMARY

Scope of the analysis

Datamonitor insight into the global vaccines market

The growth rate for the global vaccines market currently outpaces other infectious diseases sectors with predicted year-on-year growth of 10–12%. In 2010, this will equate to a market size of approximately $17 billion on a par with antivirals. Bearing in mind current dynamics, Datamonitor believes a large proportion of these sales will fall outside the existing four company oligopoly

Within the dominant high-volume pediatric segment, declining birth rates, uncertain market access and intense competition forces vaccine players to consider a range of new product strategies with varying levels of commercial risk. Examples include monoclonal antibodies, therapeutic vaccines, newer adjuvants and delivery systems

Along with smaller players, GSK and Wyeth have recognized growing unmet medical need within the treatment of nosocomial bacterial infections, especially those caused by drug-resistant Staphylococci and Enterococci. Significant global numbers of immunocompromised �eat-risk�f groups and limited antibacterial R&D increase the commercial attractiveness of this newer segment

With clear assumptions on pricing, coverage and target groups, Datamonitor commercial analyses reveals that peak global sales of a S. aureus prophylatic vaccine and therapeutic monoclonal antibody could reach $1.8 billion and $2.6 billion respectively. Market access is likely to be more feasible for the monoclonal product, as the current likelihood of mandated mass vaccination with a S. aureus vaccine is low
