Final answer:
The public service announcement likely aims to encourage vaccine uptake among pregnant women and young children, and to educate the public on the health risks associated with whooping cough, in order to prevent disease spillovers and ensure public health.
Step-by-step explanation:
The most likely motives behind the public service announcement related to whooping cough would include:
- Encourage pregnant women to take a vaccine because they are at high risk and vaccination can help prevent serious complications such as pneumonia if they get sick with the flu or whooping cough.
- Educate the public on the dangers of whooping cough, as understanding the potential severity of the disease can motivate individuals to get vaccinated.
- Promote the idea of vaccinating young children because they are particularly vulnerable to the effects of whooping cough, and vaccinating them helps prevent the spread of the illness within the population.
In light of recent outbreaks due to declining vaccination rates, these motives work together to combat the resurgence of diseases like whooping cough. Considering the economic perspective, immunizations prevent spillovers of illness to others as well as protect the individuals, making it a matter of public health and safety.
