In one region, it was noted that in a given year, there had been 3,500 cases of influenza identified in the territory. For the following year, we had a vaccine. We chose 3,000 people who were inoculated with this vaccine. Another 3,000 people were also given placebos. It was found that in the first group, the number of people with the flu decreased by 30 each year, while it decreased by 1% per year in those who took the placebo. The experiment lasted 5 years.

During these 5 years, how many fewer patients had the flu among those who had taken the vaccine compared to those who had taken the placebo? Round your calculations to the nearest person.
