What do you understand by this statement?We are fighting against Covid-19 a deadly virus. Research is going on to find a vaccine. Many medicine scientists are on the job. Many medical pharmacies are busy finding a vaccine. Few reputed companies are coming up with a statement that the vaccine is tested and is successful with some percentage. This percentage confuse us.
If a vaccine is said to be 95 percent successful, what does it mean?
Does it mean - if 100 people are vaccinated, 95 people would survive and 5 people would die?
Please clarify this doubt.
