But don’t dismiss the benefits of a booster dose of Johnson & Johnson’s vaccine. Despite the comparatively lower levels of antibodies, it may build up over a greater time period.<\/p>\n
And overall, a second dose of Johnson & Johnson’s coronavirus vaccine is likely beneficial to recipients, the Food and Drug Administration (FDA) said Wednesday, though the data is extremely limited.<\/p>\n
In a briefing document released ahead of an advisory panel meeting later this week, the FDA said it relied heavily on studies conducted by Johnson & Johnson and could not independently confirm many of the findings because data from the trials were not submitted in time.<\/p>\n
While the vaccine provides protection against severe disease for at least six months, the company said a decrease in protection over time against cases that include moderate COVID-19 was observed globally, which could be driven by waning protection or reduced efficacy against emergent SARS CoV-2 variants.<\/p>\n
Johnson & Johnson said a booster is recommended “at 6 months or later, based on the strength of the immune responses” for people ages 18 and older. But it also suggested a booster may be administered as early as two months after the initial dose; the advisory panel will discuss that evidence during the meeting.<\/p>\n
Significance:\u00a0<\/strong>Taken together with the NIH study, the data could finally provide a path forward for the 15 million recipients of Johnson & Johnson’s vaccine. But it leaves the FDA panel to grapple with a similar question they faced when the J&J vaccine was first authorized: what is the role of a booster to a vaccine that’s less effective than others that are widely available?<\/p>\n","protected":false},"excerpt":{"rendered":" But don’t dismiss the benefits of...<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[16],"tags":[],"class_list":["post-41147","post","type-post","status-publish","format-standard","hentry","category-health"],"_links":{"self":[{"href":"https:\/\/lapost.us\/index.php?rest_route=\/wp\/v2\/posts\/41147","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lapost.us\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lapost.us\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lapost.us\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lapost.us\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=41147"}],"version-history":[{"count":1,"href":"https:\/\/lapost.us\/index.php?rest_route=\/wp\/v2\/posts\/41147\/revisions"}],"predecessor-version":[{"id":41148,"href":"https:\/\/lapost.us\/index.php?rest_route=\/wp\/v2\/posts\/41147\/revisions\/41148"}],"wp:attachment":[{"href":"https:\/\/lapost.us\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=41147"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lapost.us\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=41147"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lapost.us\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=41147"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
