O mare parte din proiectele privind dezvoltarea unui vaccin contra COVID-19\u00a0 presupun injectarea solu\u0163iei \u00een bra\u0163. \u00cens\u0103, majoritatea oamenilor de \u015ftiin\u0163\u0103 descoper\u0103 acum c\u0103 eficien\u0163a medicamentului ar putea fi sporit\u0103 dac\u0103 \u00eel aplic\u0103m pe zonele-cheie: \u00een nas \u015fi \u00een g\u00eet.<\/p>\n
Majoritatea vaccinurilor care se afl\u0103 acum \u00een faza de testare presupun injectarea a dou\u0103 doze de serum \u00een bra\u0163. Speciali\u015ftii sper\u0103, \u00eens\u0103, c\u0103 r\u0103spunsul sistemului imunitar va fi mai rapid dac\u0103 medicamentul este aplicat direct pe zona cea mai afectat\u0103 de virus, aparatul respirator.<\/p>\n
Vaccin\u0103rile prin pulverizare\u00a0se afl\u0103 deja \u00een curs de dezvoltare \u00een SUA, Marea Britanie \u015fi Hong Kong \u015fi ar putea ajuta statele grav afectate s\u0103 scape de restric\u0163iile impuse, care nu fac dec\u00eet s\u0103 dea peste cap economia \u015fi via\u0163a de zi cu zi. Totodat\u0103, vaccinarea prin pulverizare ar putea ajuta la prevenirea cre\u015fterii agentului patogen \u00een nas, ceea ce ar putea limita \u015fi transmiterea rapid\u0103 a virusului.<\/p>\n
Cercet\u0103torii s-au concentrat pe dezvoltarea vaccinului cu aplicare prin injec\u0163ie, fiind considerat\u0103 cea mai rapid\u0103 form\u0103 de contact cu serul. \u00cens\u0103, premisa de la care pleac\u0103 grupurile de cercetare \u00een vaccinuri prin inhalare \u015fi pulverizare este c\u0103 aparatul respirator este c\u0103ptu\u015fit de mucoas\u0103, cu un con\u0163inut ridicat de\u00a0proteine imune, numite IgA, care ofer\u0103 o protec\u0163ie mai bun\u0103 \u00eempotriva virusurilor respiratorii. Activarea acestor proteine ar putea duce la protejarea zonelor ad\u00eenci din pl\u0103m\u00eeni, zone \u00een care virusul SARS-CoV-2 provoac\u0103 cele mai multe daune.<\/p>\n
Cei de la Altimmune pl\u0103nuiesc s\u0103 fac\u0103 test\u0103ri cu vaccinul nazal, aflat \u00een al patrulea stadiu de testare, pe un grup de bolnavi COVID-19. Instrumentul de administrare al medicamentului va sem\u0103na cu un inhalator folosit de bolnavii de astm.<\/p>\n","protected":false},"excerpt":{"rendered":"
