\nO doz\u0103 de rapel a versiunii actualizate a vaccinului Pfizer anti-COVID, modificat special pentru a combate varianta Omicron a coronavirusului, a generat un r\u0103spuns imunitar important.<\/p>\n
\nConsilierii FDA urmeaz\u0103 s\u0103 se \u00eent\u00e2lneasc\u0103 mar\u0163i pentru a discuta dac\u0103 vor actualiza vaccinurile COVID-19 pentru toamn\u0103. Este probabil ca vaccinurile actualizate s\u0103 fie reproiectate pentru a combate varianta Omicron a coronavirusului, spun exper\u0163ii cita\u0163i de Reuters.<\/p>\n
\nPfizer \u015fi BioNTech au declarat c\u0103 dozele de 30 \u015fi 60 de micrograme ale unui ser care vizeaz\u0103 doar subvarianta BA.1 Omicron care a circulat iarna trecut\u0103 au determinat o cre\u015ftere de 13,5 \u015fi 19,6 ori a titrurilor de neutralizare \u00eempotriva acestei subvariante. O versiune a injec\u0163iei care con\u0163inea at\u00e2t vaccinul reproiectat, c\u00e2t \u015fi vaccinul lor original, a determinat o cre\u015ftere de 9,1 \u015fi 10,9 ori, au spus ei.<\/p>\n
\nRezultatele au fost ob\u0163inute \u00een urma unui studiu efectuat pe 1.234 de persoane cu v\u00e2rsta de 56 de ani sau mai mult. Injec\u0163iile au fost bine tolerate de participan\u0163i, au precizat companiile.<\/p>\n
\nAce\u015ftia au precizat c\u0103 primele studii de laborator sugereaz\u0103 c\u0103 serul neutralizeaz\u0103 subvariantele Omicron BA.4 \u015fi BA.5 care au circulat mai recent, de\u015fi \u00eentr-o m\u0103sur\u0103 mai mic\u0103 dec\u00e2t \u00een cazul BA.1, cu titruri de aproximativ 3 ori mai mici.<\/p>\n
\nCompaniile continu\u0103 s\u0103 colecteze date despre c\u00e2t de bine se comport\u0103 boosterele fa\u0163\u0103 de tulpinile care au circulat mai recent.<\/p>\n
\nModerna a realizat, de asemenea, un vaccin reproiectat care vizeaz\u0103 subvarianta BA.1 Omicron. Compania a declarat c\u0103 vaccinul s\u0103u actualizat a func\u0163ionat bine \u00eempotriva subvariantelor Omicron mai recente \u015fi c\u0103 merge mai departe cu planurile de a cere aprobarea autorit\u0103\u0163ilor de reglementare.<\/p>\n","protected":false},"excerpt":{"rendered":"
