Bolstered immunity refers to having an enhanced immune system that is better prepared to fight off infections and diseases. This can be achieved in several ways:
Herd Immunity occurs when a large portion of the population is immune to a contagious disease, providing indirect protection to those who aren't immune. For example, if 95% of people are vaccinated against measles, a measles outbreak likely won't spread because there aren't enough vulnerable hosts.
During a pandemic like COVID-19, using tools like social distancing, masks, and proper hygiene habits bolsters community immunity. These measures slow disease transmission rates so healthcare systems aren't overwhelmed caring for the severely ill at once. Flattening the curve saves lives.
Once effective vaccines are developed, widespread vaccination further controls a pandemic by bolstering immunity in individuals and communities. Herd immunity against the SARS-CoV-2 virus is estimated to be achieved with 60-90% of the population immunized, either from natural infection or vaccination. Achieving this would allow resuming normal activities safely.
In summary, strengthened individual and community immunity is crucial for defending public health and providing the best protection from infectious disease threats like the coronavirus. Practicing healthy habits, getting recommended vaccines, treating immunodeficiencies, and following pandemic guidance bolsters immunity. Achieving herd immunity with COVID-19 immunization will be key to ending this pandemic.
