Question

Explain why vaccinations and social-distancings in times of the Corona pandemic are both

examples of positive externalities.

Answer 1

Vaccinations are a type of positive externalities because those who are vaccinated are protected and if enough people are vaccination then others are less likely to contract that disease.

Answer 2

as they prevent further spreading of the virus. vaccinations create phagocytes which will ingest the virus cells. and self isolation will prevent the virus (which are droplets) from passing onto one another.
