@sonuujjawal26 That’s a classic question 😄 — and the answer is quite interesting.
Here in Brazil, that little mark on the arm comes from the BCG vaccine, which protects against severe forms of tuberculosis.
💉 Why does the BCG leave a mark?
Because it causes a local reaction in the body.
...
@sonuujjawal26 Not all countries give BCG to everyone.
In countries where tuberculosis is rare (like the United States and Germany), the vaccine is not routinely given to all babies
It’s limited to risk groups.
As a result, many people simply never received the BCG, so they don’t have the mark
@sonuujjawal26 It’s usually on the right arm because that’s the standard application site.
🤔 Why don’t other vaccines leave a mark?
Because BCG is applied in a different way (intradermally, very superficially), which creates a more visible local reaction than most other vaccines.
@sonuujjawal26 it’s like a “mini battle” of the immune system happening in the skin.
🧠 Interesting facts
The mark usually appears weeks after the vaccination.
Not everyone develops a scar — and that doesn’t mean the vaccine failed.
@sonuujjawal26 The vaccine uses a weakened bacterium (the Calmette–Guérin bacillus).
When it’s applied, the body reacts to “learn” how to defend itself.
This causes inflammation at the site, which turns into a small sore and then heals.
The remaining scar is exactly that little mark.
In short:
@peXada@JessiqueOfc@Tumultobracervo Numa briga de um Pitbull e um caramelo, dei um mata leão no Pitbull, demorou para soltar. Uma dedada seria mais eficiente.
@adeptababayaga@maconhi1da Uma vez apartei uma briga entre uma Pitbull e uma vira lata (nenhum meu... Aliás, prefiro gatos). Mantive a calma, esperei, me posicionei e dei um mata-leão na Pitbull. Precisou de uns 40s para ela soltar. Mas foi a única solução viável naquele momento.
@BarbaridadeCass@guilhermeas001@confissoeszxxx Cobrar menos, relaxar e deixar acontecer... já é muita coisa pra pensar. Ele precisa tirar o estigma de broxar. Ele já está carregando esse fardo
