Sorry but you are wrong. 95% effective means that in a situation where 100 people who are not vaccinated get sick, only 5 with vaccine get sick. Think of it this way. If seat belts are 60% effective at reducing crash deaths, it does not mean that 40% of seat-belt wearers will die in a car crash.
More technically, start with 10000 people. Give 5000 the shots. Watch them for 3 months. If out of the vaccinated 5000 you get 5 sick people and out of the not vaccinated group you get 100 sick people the vaccine was 95% effective. It reduced cases by 95%
Your statement that 5% of the vaccinated group gets sick is wrong. In my example 5% of the 5000 people would mean 250 get sick using your misunderstanding. As you can see that is not how the statistic is calculated. 95% efficacy does not mean that 5% of the vaccinated people will get sick.
