There is \u201climited data on efficacy\u201d of the vaccines beyond that interval, according to the guidance, but if the second dose is administered later \u201cthere is no need to restart the series.\u201d<\/p>\n\n\n\n<p>Both vaccines authorized for emergency use in the U.S. were cleared based on trials of two doses weeks apart. A grace period of four days ahead of schedule would be considered valid for a second dose, but people shouldn\u2019t receive the second dose earlier than that.<\/p>\n\n\n\n<p>The CDC made the change in response to feedback on earlier guidance, agency spokeswoman Kristen Nordlund said in an email. It\u2019s intended to provide flexibility in situations where patients can\u2019t return on a specific date or their circumstances change, for example if they enter or leave a nursing home, she said. The CDC doesn\u2019t want guidance \u201cto be so rigid that it creates unintended barriers,\u201d she said.<\/p>\n\n\n\n<p>Analysis of the Pfizer shot included some people who got the second dose as late as 42 days after the first, she said. The agency isn\u2019t recommending the change to stretch the supply of doses \u201cbut rather to address feasibility issues,\u201d she said.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Not Interchangeable<\/h3>\n\n\n\n<p>The CDC also reiterated that doses from the two vaccines are not interchangeable and people should get a second dose of the same product. In \u201cexceptional situations\u201d when the initial vaccine is unknown or unavailable, \u201cany available mRNA COVID-19 vaccine may be administered at a minimum interval of 28 days,\u201d the agency said.<\/p>\n\n\n\n<p>The CDC said the Covid-19 vaccines generally should be administered alone, not simultaneously with other inoculations, such as for the flu.<\/p>\n\n\n\n<p>The need for follow-up doses at specified intervals is one layer of complication in the national vaccination campaign. Shortages of doses and confusion over supply has led to long waits and frustration, even as the incoming Biden administration pledges to accelerate the delivery of vaccines.<\/p>\n\n\n\n<p>A single-dose Covid vaccine from Johnson &amp; Johnson is in late-stage trials now, with data expected to be analyzed in the weeks ahead.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">FDA Stance<\/h3>\n\n\n\n<p>The FDA earlier this month&nbsp;resisted pressure&nbsp;to stretch supply by adding time between the two shots.<\/p>\n\n\n\n<p>Then-FDA Commissioner Stephen Hahn and Peter Marks, head of the agency\u2019s office that oversees vaccines, signed on to a statement that said extending the time between shots hadn\u2019t been studied and \u201cmay ultimately be counterproductive to public health.\u201d<\/p>\n\n\n\n<p>While Hahn has left the agency, Marks, a career employee, remains.<\/p>\n\n\n\n<p>Biden\u2019s plan for combating the pandemic released Thursday includes some wiggle room for alternative dosing schedules.<\/p>\n\n\n\n<p>\u201cThe federal government will explore dose-sparing strategies that have the potential to substantially expand vaccine supply, while maintaining a commitment to abiding by FDA recommendations,\u201d according to the plan.<\/p>\n","protected":false},"excerpt":{"rendered":"<div class=\"mh-excerpt\"><p>The guidance posted in a Jan.
