A person who take 1 dose of a vaccine is protected 95%.

If the same person take two doses of the same vaccina, what is the protection he gets?

Update:

I need calculus and if possible formulas.

Update 2:

This is a simple Math problem. Just need toknow how to accumulate two times of 95%

    Vaccines do not work like that. Assuming you mean CV19, it takes TWO doses of vaccine given 1 month apart to kick start the immune system response. If you stop at one dose, you'd get 0% protection.

    Depends on the vaccine, some are one dose and immune for life, some need to be repeated.

    Do you believe every commercial? 

    If you learn a bit more about this subject, you never would consider a vaccine again.

    Between 95-99%.
