How did the discovery of an effective vaccine by Louis Pasteur lead to the growth of the Europe's population?

I believe the answer is
Vaccines reduced the number of diseases in the world, so fewer people suffered illness.

I hope this helps :)

The discovery of an effective vaccine by Louis Pasteur lead to the growth of Europe's population because the study of microorganisms and how they lead to fermentation also spurred the growth of other industries.

Due to the invention or discovery of Louis Pasteur, industries such as pasteurization, beer production, wine production silk production, and the production of drugs that helped to cure diseases such as rabies and anthrax expanded thus creating an increase in population.

It is to be noted that Louis Pasteur's discovery was in the year 1881.
