Prospects for new viral vaccines.

Area of Science:

• * Veterinary and Human Medicine
• * Vaccinology and Virology

Background:

• * Animal virology has historically driven significant advancements in preventive medicine for both humans and animals.
• * Vaccine development has led to substantial cost savings in healthcare by controlling diseases like smallpox, poliomyelitis, yellow fever, and measles.

Purpose of the Study:

• * To review the contributions of animal virology to vaccine development.
• * To identify areas for future vaccine development, including influenza, herpes viruses, respiratory syncytial virus, rotavirus, and hepatitis viruses.
• * To discuss vaccine formulation strategies, particularly those utilizing viral genetics for tailored vaccine viruses.

Main Methods:

• * Review of existing literature on animal virology and vaccine development.
• * Analysis of cost-benefit data for established vaccines.
• * Case study approach examining the development of inactivated hepatitis B vaccine.
• * Assessment of molecular cloning techniques for vaccine production.

Main Results:

• * Established vaccines have demonstrated significant economic benefits through disease control.
• * Key areas for future vaccine research include influenza, herpesviruses, RSV, rotavirus, and hepatitis A, B, and non-A/non-B.
• * Viral genetics offers promising approaches for creating safer and more effective 'tailor-made' vaccines.
• * Progress in cloning hepatitis B virus DNA has enabled the assessment of purified viral polypeptide vaccines.

Conclusions:

• * Animal virology remains a critical field for developing new and improved vaccines.
• * Genetic engineering holds significant potential for designing next-generation vaccines with enhanced properties.
• * The development of hepatitis B vaccines serves as a model for future vaccine innovation.
