Given that antibody titers are key, with an igG half life of 27 days, a standard coronavirus reinfection period of 90 days, and using the half life equation, we find the vaccine lifetime to be 157 days after the 2nd dose.

Find the antibody critical threshold:

Nt = No × (0.5) ^ ( t / tHalf)

Nt = 100 × (0.5) ^ (90 / 27)

Nt = 10 (10% of antibodies provided by natural infection)

Find the vaccine lifetime, given 4x antibodies induced by vaccine:

10 = 400 × (0.5) ^ (t / 27)

(10 / 400) = (0.5) ^ (t / 27)

log(10 / 400) = (t / 27) × log(0.5)

t = 143 days (after 2nd dose) + 14 days = 157 days
