It found the booster dose increased neutralizing antibody responses against the original virus as well as B.1.351 and P.1, two variants that have since spread to other countries, including the U.S.<\/p>\n<p>The company also said a booster shot of its other vaccine, which it is calling mRNA-1273.351, generated an even better immune response over its current vaccine against the B.1.351 variant from South Africa. The new vaccine is a variant-specific booster shot intended to target B.1.351.<\/p>\n<p>The preliminary results, which Moderna says will be published online, have not yet been peer-reviewed.<\/p>\n<p>&quot;As we seek to defeat the ongoing pandemic, we remain committed to being proactive as the virus evolves,&quot; Moderna CEO Stephane Bancel said in a press release. &quot;We are encouraged by these new data, which reinforce our confidence that our booster strategy should be protective against these newly detected variants.&quot;<\/p>\n<p>Moderna said side effects were similar to those observed after the second dose of the vaccine in the previously reported studies. Side effects included pain at the injection site, fatigue and headache as well as muscle and joint pain.<\/p>\n<p>The new data comes as drugmakers and scientists now say people will likely need a booster shot of the Covid-19 vaccines and possibly additional shots each year, just like for the seasonal flu.<\/p>\n<p>Moderna&#x27;s vaccine requires two doses given four weeks apart. Like Pfizer&#x27;s and Johnson &amp; Johnson&#x27;s, the shot is highly effective against Covid, though company executives and officials now say they expect that strong protection to wane over time. Pfizer&#x27;s vaccine is also a two-dose regimen while the J&amp;J immunization is just one jab.<\/p>\n<p>White House chief medical advisor Dr. Anthony Fauci has previously said Americans may need to get booster shots to better protect against variants.<\/p>\n<h2>CNBC Health &amp; Science <\/h2>\n<p>Read CNBC&#x27;s latest coverage of the Covid pandemic:<\/p>\n<p>India foreign minister self-isolating after Covid scare at UK&#x27;s in-person G-7 summit<\/p>\n<p>Why India \u2014 the world&#x27;s biggest producer of Covid vaccines \u2014 has a major shortage of doses\u00a0\u00a0\u00a0<\/p>\n<p>Biden&#x27;s new Covid vaccination goal is for 70% of adults to have at least one shot by July 4 <\/p>\n<p>Pfizer scientist expects elderly, people with underlying conditions to be first to get Covid booster\u00a0shots<\/p>\n<p>Earlier Wednesday, U.S. health officials said highly contagious variants remain a &quot;wild card&quot; in their nationwide campaign to get most American adults vaccinated by the Fourth of July.<\/p>\n<p>A Centers for Disease Control and Prevention\u00a0report published Wednesday projected Covid-19 cases would surge through May \u2014 due to the highly contagious B.1.1.7 variant first identified in the U.K. \u2014 before sharply declining by July as vaccinations drive down infections. Still, variants threaten to reverse the nation&#x27;s progress, officials said,<\/p>\n<p>&quot;We are seeing that our current vaccines are protecting against the contaminant variants circulating in the country. Simply put, the sooner we get more and more people vaccinated, the sooner we will all get back to normal,&quot; \u00a0CDC Director Dr. Rochelle Walensky said during a White House Covid news briefing.<\/p>\n<p>Moderna is evaluating three approaches to increasing immunity. The first approach would use variant-specific booster shots, such as mRNA-1273.351, but at a lower dose than the original vaccine. The second one would combine the original vaccine with a variant-specific vaccine into a single shot at 50 micrograms or lower, Moderna said. The third would test a third shot of the original vaccine at a lower dosage.<\/p>\n<p>Bancel told CNBC last month that the company\u00a0hopes to have a booster shot\u00a0for its two-dose vaccine available in the fall.<\/p>\n<p>Source: <a href=\"https:\/\/www.cnbc.com\/2021\/05\/05\/covid-booster-shot-moderna-says-vaccine-generates-promising-immune-response-against-variants.html\" target=\"_blank\" rel=\"noopener\">Read Full Article<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Moderna is testing a 50-microgram dose of<\/p>\n","protected":false},"author":3,"featured_media":123914,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23051],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v21.7 -
