Stepping Up the Pace in Vaccine Development and Production
Vaccinations help protect against diseases and are one of the most important and effective preventive health measures available. The principle behind vaccination is to boost the individual’s own immune defences: vaccines expose the body to a minute quantity of pathogen-derived materials. The immune system responds by developing the appropriate immune cells and stores these protective cells as a kind of ‘immunological memory’. Not only does the vaccinated patient build up protection against the disease through vaccination, but in some cases, high vaccination rates among the general population make it harder for the individual pathogens to spread (called herd immunity), which may ultimately even result in their elimination.
