There are some examples for the benefit of people?

Hi! I wrote an essay and I don’t know how to express and idea so i quote: “First of all there are some examples for the benefit of people, such as scientific experiments, medical researches, drugs, vaccines, etc. that show us fight against severe diseases” Is that expression correct?

.
First of all, progress has benefited people with scientific and medical research, drugs and vaccines that help us fight against severe diseases.
