群體免疫的力量

Herd immunity arises when enough people are vaccinated to halt the spread of disease, protecting even those too vulnerable or young for vaccines. Decades ago, infectious diseases like polio and measles devastated communities, but vaccination campaigns slashed those risks. During the 2009 H1N1 pandemic, hospitals that vaccinated 93 percent of at-risk groups saw cases drop from over 250 to zero. Vaccination is not just self-protection; it is an act that safeguards entire populations.
