Conform INSP, vaccinurile con\u0163in forme modificate de virusuri sau bacterii care nu cauzeaz\u0103 boala, dar care \u00ee\u0163i „\u00eenva\u0163\u0103” sistemul imunitar ce s\u0103 fac\u0103 \u00een caz c\u0103 e\u015fti atacat vreodat\u0103 de virusurile sau bacteriile reale, poten\u0163ial periculoase.  C\u00e2nd e\u015fti vaccinat, sistemul imun r\u0103spunde prin crearea anticorpilor care s\u0103 lupte cu virusul sau microbul respectiv. Dup\u0103 vaccinare, corpul p\u0103streaz\u0103 memoria intruziunii specifice. Dac\u0103 vine vreodat\u0103 \u00een contact cu microbul sau virusul real, anticorpii potrivi\u0163i \u00eel distrug rapid, \u00eenainte de-a putea s\u0103 produc\u0103 \u00eemboln\u0103virea.<\/p>\n\n\n\n

Conform OMS, COVID-19 Vaccines Modern<\/strong>a<\/strong> \u015fi Pfizer<\/strong> ac\u021bioneaz\u0103 preg\u0103tind organismul s\u0103 se apere \u00eempotriva COVID-19. Con\u021bin o molecul\u0103 numit\u0103 ARNm care cuprinde instruc\u021biuni pentru producerea proteinei virale de suprafa\u021b\u0103. Aceasta este o protein\u0103 de pe suprafa\u021ba virusului SARS-CoV-2, de care virusul are nevoie pentru a p\u0103trunde \u00een celulele organismului. C\u00e2nd se administreaz\u0103 vaccinul la o persoan\u0103, anumite celule din organismul s\u0103u citesc instruc\u021biunile ARNm \u0219i produc temporar proteina viral\u0103 de suprafa\u021b\u0103. Sistemul imunitar al persoanei va recunoa\u0219te apoi aceast\u0103 protein\u0103 ca fiind str\u0103in\u0103, va produce anticorpi \u0219i va activa limfocitele T (globulele albe) pentru a o ataca. Dup\u0103 vaccinare, virusul vaccinului p\u0103trunde \u00een c\u00e2teva celule umane. Acestea folosesc gena pentru a produce proteina spike. Sistemul imunitar recunoa\u0219te acest lucru ca un corp str\u0103in \u0219i reac\u021bioneaz\u0103 form\u00e2nd anticorpi \u0219i celule T, care protejeaz\u0103 \u00een mod ideal \u00eempotriva infec\u021biei cu coronavirusul Sars-Cov-2.<\/p>\n\n\n\n

Dac\u0103, ulterior, persoana intr\u0103 \u00een contact cu virusul SARS-CoV-2, sistemul s\u0103u imunitar va recunoa\u0219te virusul \u0219i va fi preg\u0103tit s\u0103 apere organismul de acesta. Molecula ARNm din vaccin nu r\u0103m\u00e2ne \u00een organism, ci se descompune la scurt timp dup\u0103 vaccinare.<\/p>\n\n\n\n

Vaccinul \u00eempotriva COVID-19 dezvoltat de AstraZeneca<\/strong> con\u021bine un adenovirus non-uman care nu se poate replica \u0219i nu poate provoca boli. Adenovirusul a fost modificat pentru a con\u021bine informa\u021bia necesar\u0103 producerii proteinei spike (cea care se g\u0103se\u0219te pe suprafa\u021ba virusului SARS-CoV-2). Odat\u0103 ce vaccinul este administrat, adenovirusul furnizeaz\u0103 aceast\u0103 informa\u021bie c\u0103tre celulele umane, care \u00eencep s\u0103 produc\u0103 proteina spike. Sistemul imunitar al persoanei va trata aceast\u0103 protein\u0103 spike ca fiind str\u0103in\u0103 \u0219i va produce un r\u0103spuns imun \u2013 anticorpi \u0219i celule T \u2013 \u00eempotriva sa. Dac\u0103 persoana vaccinat\u0103 intr\u0103 \u00een contact cu virusul SARS-CoV-2, sistemul imunitar \u00eel va recunoa\u0219te \u0219i va fi preg\u0103tit s\u0103-l atace: anticorpii \u0219i celulele T vor lucra \u00eempreun\u0103 pentru a elimina virusul. C\u00e2nd sistemul imunitar ia contact pentru prima dat\u0103 cu un vaccin, acesta activeaz\u0103 dou\u0103 tipuri importante de celule albe din s\u00e2nge. Primele sunt celulele B din plasm\u0103, ale c\u0103ror principal rol este s\u0103 produc\u0103 anticorpi. Din p\u0103cate, acest tip de celul\u0103 are o durat\u0103 scurt\u0103 de via\u0163\u0103. De aceea, chiar dac\u0103 organismul va \u201edeborda\u201d de anticorpi \u00een doar c\u00e2teva s\u0103pt\u0103m\u00e2ni, f\u0103r\u0103 al doilea vaccin (rapel), acest efect este de multe ori urmat de un declin rapid.<\/p>
