But those vaccines target the original coronavirus strain and their effectiveness against any infection dropped markedly when the super-contagious omicron mutant emerged.<\/p>\n<p>Now with omicron&#8217;s even more transmissible relatives spreading widely, the Food and Drug Administration is considering ordering a recipe change for the vaccines made by both Pfizer and rival Moderna in hopes that modified boosters could better protect against another COVID-19 surge expected this fall and winter.<\/p>\n<p>Pfizer and its partner BioNTech studied two different ways of updating their shots\u2014targeting just omicron, or a combination booster that adds omicron protection to the original vaccine. They also tested whether to keep today&#8217;s standard dosage\u201430 micrograms\u2014or to double the shots&#8217; strength.<\/p>\n<p>In a study of more than 1,200 middle-aged and older adults who&#8217;d already had three vaccine doses, Pfizer said both booster <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>roaches spurred a substantial jump in omicron-fighting antibodies.<\/p>\n<p>&#8220;Based on these data, we believe we have two very strong omicron-adapted candidates,&#8221; Pfizer CEO Albert Bourla said in a statement.<\/p>\n<p>Pfizer&#8217;s omicron-only booster sparked the strongest immune response against that variant.<\/p>\n<p>But many experts say combination shots may be the best approach because they would retain the proven benefits of the original COVID-19 vaccine while adding new protection against omicron. And Pfizer said a month after people received its combo shot, they had a 9 to 11-fold increase in omicron-fighting antibodies. That&#8217;s more than 1.5 times better than another dose of the original vaccine.<\/p>\n<p>And importantly, preliminary lab studies show the tweaked shots also produce antibodies capable of fighting omicron&#8217;s genetically distinct relatives named BA.4 and BA.5, although those levels weren&#8217;t nearly as high.<\/p>\n<p>Moderna recently announced similar results from tests of its combination shot, what scientists call a &#8220;bivalent&#8221; vaccine.<\/p>\n<p>The studies weren&#8217;t designed to track how well updated boosters prevented COVID-19 cases. Nor is it clear how long any added protection would last.<\/p>\n<p>But the FDA&#8217;s scientific advisers will publicly debate the data on Tuesday, as they grapple with whether to recommend a change to the vaccines&#8217; recipes\u2014ahead of similar decisions by other countries.\n                                                                                                                        <\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                                                                        Moderna says updated COVID shot boosts omicron protection\n                                                                                    <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<p class=\"article-main__note mt-4\">\n                                                \u00a9 2022 The Associated Press.
