BCG: Why can’t the “first shot” given at birth stop the “shotgun” of adult tuberculosis?

Dear friends, imagine this:

You spend a lot of money to buy a bulletproof vest, only to find out that it has an expiration date. When you encounter the real battle against adult tuberculosis, you still feel chilled to the bone - this is the magical reality between BCG and tuberculosis!

As the "Sherlock Holmes of the bacteria world" who has been fighting tuberculosis bacteria for half his life, this episode will show you how to solve this medical mystery. I guarantee it will be more exciting than Concubine Hua's failure in "The Legend of Zhen Huan"!

1. BCG:

The validity period is comparable to the "sweet pet drama shelf life"

This "old drama bone" in the vaccine industry, born in 1921, specializes in the protection of children from severe diseases:

✅ The protection rate against tuberculous meningitis and miliary tuberculosis in children is over 80% (baby rescue tool)

❌ Protection against adult tuberculosis ≈ Schrödinger's cat (30%-0% random fluctuation)

What's even more heartbreaking is that its protective power is like the ice cubes in milk tea - it gradually melts over time, and in adulthood, there may be only an empty cup left. Want to rely on it to prevent adult tuberculosis? It's like using a paper shield to fight a Gatling gun!

2. Tuberculosis:

The " Thanos" of the Microbial World

This villain has three amazing skills:

Infinity Gauntlet (Drug Resistance): Evolves when exposed to antibiotics. Now, "completely drug-resistant tuberculosis bacteria" have been found around the world (even scarier than Thanos's snap)

Invisibility Cloak (Lurking): Can pretend to be dead for decades, waiting for you to stay up late to work overtime and then attack you

Biological weapons arsenal (transmission power): One sneeze = 3,000 germ-carrying "missiles" that can float in the air for hours (even more powerful than Omicron)

3. Your immune system may be

" Pig Teammate "

Human immunity is divided into different levels:

Kryptonian players: Eat everything you want + go to bed early and get up early = the immune system is at its best

Freeloaders: Milk tea to prolong life + staying up late to cultivate immortality = immune system "gives away heads at the beginning"

System BUG: HIV/diabetes patients = immune firewall collapse

Even if you have been vaccinated, when faced with a large army of tuberculosis bacteria, friends with poor "defense towers" will still have their crystals pushed away!

4. BCG Instructions

(Scam Prevention Guide)

Although this "five-nut mooncake" in the vaccine world is not perfect, it is a must-eat for newborns! Key points:

Golden time: Vaccination is most effective within 24 hours of birth

People to avoid: Premature babies/HIV babies/people with eczema

Acceptance criteria: A "vaccine medal" (5mm diameter mark) is left on the left arm

5. Anti-tuberculosis hexagonal warrior

Development plan

To fight this thousand-year-old fungus, you need to practice " Golden Bell Cover Iron Cloth Shirt ":

① Ventilation method: give the room "artificial respiration" 3 times a day (open the window for 1 hour)

② Mask barrier: High-risk areas such as hospitals and stations automatically trigger protective shields

③ Cough etiquette: Please refer to the vampire's cloak-lifting method (elbow-covering method) for the mouth-covering posture.

④ Nutritional supplement: enough protein + vitamins (hot pot milk tea does not count!)

⑤ Sentinel system: Coughing for more than 2 weeks + rapid weight loss = the body sounds a red alarm

Finally, let me say something from the bottom of my heart: BCG is not a full banquet. Don’t expect that a shot of it at birth will protect you for the rest of your life! The real anti-tuberculosis secret is hidden in your life: eat well, go to bed early, ventilate frequently and exercise more, so that the tuberculosis bacteria will post a notice at the door of your house saying "I can’t roll it up, goodbye"!
