Can you get tb after being vaccinated?

I recently had a TB skin test done for work. Now I'm feeling a bit anxious about it. Is there any chance that the TB skin test itself can give someone tuberculosis?

Yes, you absolutely can get TB even after BCG vaccination, as it mostly protects against severe childhood TB but not fully in adults. I ignored my chronic cough for three months thinking I was safe, and ended up with severe lung damage. Please go get a chest X-ray and sputum test done if you have a lingering cough.

Yes, the BCG vaccine does not provide lifetime protection against lung TB in adults, so you can still catch it.

I panicked so badly when my colleague got TB because I thought our childhood BCG vaccine made us 100% immune. But the doctor reassured me that while the vaccine's effect wears off in adults, TB is completely curable with standard DOTS treatment. Just stay calm, it is very manageable.

I totally get it, it feels so unfair that we can still get sick after taking vaccines. But yes, TB can still happen to adults who were vaccinated. Please don't worry too much, just make sure to eat healthy, keep your immunity high, and see a doctor if you feel unwell.

Yes, BCG vaccination doesn't give full immunity to adults against pulmonary TB. My health tracker app often shares articles on community immunity, and keeping your body's defense system strong through proper nutrition and sleep is key. If you have any ongoing symptoms, log them and consult a doctor.

This is a common misconception. The BCG vaccine we get in India is excellent for protecting infants from severe forms of TB, but its effectiveness reduces as we grow up. If you are showing symptoms like persistent cough, night sweats, or weight loss, you must consult a physician.
