Covid-19: Does vaccination completely prevent infection?

If you are wondering whether the vaccination of Covid-19 completely prevent infection, then the answer is definitely NO. Vaccination definitely protects you but when you get vaccinated, you can still catch the virus but you won’t fall sick very seriously.

Remember, vaccination protects you from the disease but not from the infection.

We all know that every person’s immune system is different and functions differently. So, when a vaccine is 95 per cent effective then it means 95 per cent of people, who receive the vaccine won’t fall ill. These people, who gets vaccinated, could be protected completely from the infection or else they can get infected but remain asymptomatic because their immunity systems erases the virus verry quickly.

And the remaining five per cent of vaccinated people can become infected and even fall sick but they are extremely unlikely to be hospitalized.

Finally, one can say that vaccination doesn’t protect you from getting infected but improves your immune system to fight against the Coronavirus. So, it is always good to get vaccinated.
