Hello doctor, i m 22 weeks
pregnant. I had taken 1st tetnus shot on starting of my pregnancy around 29 december. Next shot i took this april 29. I am not sure about my immunization to tetnus as child but in years 2019 and 2020 i have taken around 3-4 shots of tetnus due to injuries.
are my tetnus shots waste as i dont know wether i was previously immunized?
i have taken last shot on 29 april 2021 and got hurt with rusted iron rod (mild cut and bit of blood) do i need a dose of tetnus again?
