Két adag Pfizer / BioNTech vakcina legalább 95% -os védelmet nyújt a covid-19 fertőzés, kórházi kezelés vagy halál ellen. Ezt állítja az izraeli lakosság körében gyűjtött adatokon alapuló tanulmány.
Egy adag Pfizer / BioNTech vakcina 58% -os védelmet nyújt a koronavírus fertőzés ellen. A kórházi kezelés kockázata 76 százalékkal, a covid-19 okozta halálozás kockázata 77 százalékkal csökken az első adag után. A The Lancet című rangos tudományos folyóiratban megjelent tanulmány szerzői szerint kutatásaik megerősítik a második adag fontosságát.
Hét nappal a második adag után a fertőzés elleni védelem 95,3 százalékra emelkedik. A teljesen beoltott betegek halálozásának kockázata 96,7 százalékkal csökken. A kórházi kezelés kockázata is csökken, 97,2 százalékkal. Tizennégy nappal a második adag után ezek az értékek kissé növekednek.
"Az oltóanyag egyetlen adagjára való hivatkozás valószínűleg nem teljesen bölcs" - vonják le a szerzők. A vakcinát többadagosként fejlesztették ki, és az embereknek tiszteletben kell tartaniuk ezt a rendszert. Az Egyesült Államokban például az orvosok megjegyezték, hogy több mint ötmillió amerikai elmulasztotta a második dózis covid-19 vakcina beadásának határidejét.
Az izraeli lakosság körében gyűjtött adatokon alapuló új tanulmány azonban megerősíti, hogy a második adag bevétele valóban kulcsfontosságú a magas védelem megszerzéséhez. "Ezenkívül keveset tudni arról, hogy a teljes oltáshoz képest mennyi ideig tart a védelem egyetlen adag után. Lehetséges, hogy az egyetlen dózis utáni védelem kevesebb időre ad védettséget, különösen egy olyan környezetben, ahol új koronavírus mutációk jelennek meg ”- tették hozzá a kutatók.
"Eddig a világ egyetlen országa sem írta le a covid-19 elleni országos oltási kampány népegészségügyi hatásait. Ezek a megfigyelések rendkívül fontosak, mert bár sok kihívás továbbra is fennáll, valódi reményt kínálnak arra, hogy az oltások végül legyőzik a járványt "- kommentálta vezető írója és orvos, Sharon Alroy-Preis a The Guardian-nak.
A tanulmány szerzői azonban rámutatnak, hogy sok olyan ország van, amelyiknek alig van reménye Izrael sikereinek megismétlésére. A Pfizer / BioNTech vakcina globális használatát korlátozzák az ellátási problémák, a magas költségek és az anyag rendkívül alacsony hőmérsékleten történő tárolásának szükségessége.
Izrael csak a Pfizer vakcinával oltja be, amelyet a vállalat szállított, az ország pedig közzétette egy olyan nemzeti oltási program eredményeit, amely a való életben bizonyítja hatékonyságát. Az ország a legmagasabb oltási rátával büszkélkedhet a világon. A World of Data adatai szerint az izraeliek 62 százaléka már megkapta a vakcina mindkét adagját.
Összegzés a tanulmány alapján
Az 1. adag Pfizer / BioNTech vakcina után :
- a vakcina 58% -os védelmet nyújt a SARS-Cov-2 fertőzés ellen
- a kórházi kezelés kockázata 76 százalékkal csökken
- halálozás kockázata 77 százalékkal csökken
Az 2. adag Pfizer / BioNTech vakcina után:
- 7 nappal a 2. adag után a fertőzés elleni védelem 95,3 százalékra emelkedik
- a kórházi kezelés kockázata csökken 97,2 százalékkal
- a halálozásának kockázata 96,7 százalékkal csökken
- További 14 nap után még tovább enyhnén emelkedik a védettség
- Fontos mind a két adag beadása.
