Start by listing what each option claims about herd immunity so you can compare them clearly.
Option 1: 'It keeps cattle healthy' — This is misleading for herd immunity in humans. Herd immunity concepts apply to human populations and vaccination coverage to protect people, not livestock health. The statement conflates animal health with human public health and is generally incorrect in the context of human disease prevention.
Option 2: 'It protects vulnerable populations (babies, elderly, immunocompromised) from diseases that they cannot be vaccinated against' — This is true. Herd immunity reduces the likelihood of disease spread in the community, lowering exposure for those who cannot be vaccinated or who have weaker immune responses, thereby protecting them.
Option 3: 'It slows or stops the spread of disease in a population' — This is also true. When a large portion of the community is immune, the transmission chain is disrupted, reducing or halting outbreaks.
Option 4: 'Both answers 2 and 3' — This is correct because it accurately combines the two valid statements above: herd immunity protects vulnerable groups and slows or stops disease spread.
To finish, consider the overarching logic: herd immunity functions to reduce transmission and shield those who cannot be vaccinated or mount an adequate immune response, which directly aligns with options 2 and 3. Option 1 misapplies the concept to cattle and thus is not aligned with human public health principles, making it inaccurate in this context.
