moram da podelim sledeću fascinaciju sa cenjenim sagita odijensom: shvatila sam da ogroman broj lekara (a verovatno i ostatak ljudske populacije) smatra da imamo efikasnu vakcinu protiv tuberkuloze.
e pa nemamo.
postojeća vakcina štiti protiv TB meningitisa (u 60-80% slučajeva) koji se javlja kod dece, al slabo štiti bolje rečeno ne štiti protiv respiratornog oblika tuberkuloze koji se primarno manifestuje kod odraslih osoba. meaning: to što ste primili BCG vakcinu vas 99% neće zaštititi od respiratorne tuberkuloze. sreća pa postoje efikasni lekovi, premda već cirkulišu sojevi Mycobacterium tuberculosis koji su rezistentni na postojeće lekove.

Tuberculosis (TB) remains as an important infectious disease and public health concern worldwide. According to the latest World Health Organization (WHO) report, there were an estimated 8.6 million incident cases of TB in 2012 and 1.3 million deaths were attributed to the disease. More than half a million cases occurred in children and 320,000 deaths were reported among HIV-infected persons [1]. However, even more disturbing is the emergence of drug resistance. In 2012, there were an estimated 450,000 cases of multidrug resistant (MDR)-TB and 170,000 deaths were due to it. MDR-TB is caused by strains of Mycobacterium tuberculosis that are resistant to at least rifampicin and isoniazid, two key drugs in the treatment of the disease. Since 2006, it has been recognized the presence of even more resistant strains of M. tuberculosis labelled as extensively drug resistant (XDR)-TB [2,3,4]. These strains in addition to being MDR are also resistant to any fluoroquinolone and to at least one of the injectable second-line drugs: kanamycin, capreomycin or amikacin. More recently, a more worrying situation has emerged with the description of M. tuberculosis strains that have been found resistant to all antibiotics that were available for testing, a situation labelled as totally drug resistant (TDR)-TB [5,6,7]. Early detection of all forms of drug resistance in TB is a key factor to reduce and contain the spread of these resistant strains.


btw, čisto kao crtica: trenutno imamo (licencirane) vakcine protiv 26 infektivnih bolesti. SAMO 26.
That’s how it is with people. Nobody cares how it works as long as it works.

Možda će anti-vakseri konačno da se smire. Ha.

Evo, jedne lepe vesti:

Africa declared free of wild polio in 'milestone'

Naravno, isključivi razlog što je ovo postignuto je da je vakcina razvijena i učinjena dostupnom uz velike napore (članak govori o tome kako je nigerijska vlada uložila mnogo truda da dosegne udaljene oblasti u kojima se, pa, puca),a verovatno ćemo za par decenija slušati nigerijske antivaksere kako vrište da je vakcina prevara, izaziva autizam itd.

It Sure Looks Like Humans Have Found a Way to Reverse Aging

nije dovoljno samo produžiti telomere, najbitnije je sprečiti mutacije koje mogu odvesti kanceru te verujem da se radi i na tome. but who wants to live forever?
