The Centers for Disease Control and Prevention have changed its definition of a “close contact,” which impacts the agency’s recommendation on who should quarantine amid the coronavirus pandemic.Previously, the CDC recommended that those who were within 6 feet for 15 minutes of someone infected with the coronavirus should quarantine for two weeks. Now, the CDC recommends that those who are in contact with someone infected for 15 minutes over a 24-hour period should quarantine.The CDC offers the following recommendations for those who have been in contact with someone recently infected with the coronavirus:Stay away from others, especially people who are at higher risk for getting very sick from COVID-19, such as older adults and people with other medical conditions, if possible.If you have been around someone with COVID-19, stay home and away from others for 14 days (self-quarantine) after your last contact with that person and monitor your health.If you have a fever, cough or other symptoms of COVID-19, stay home and away from others (except to get medical care or testing, if recommended).If you need support or assistance while in self-quarantine, your health department or community organizations may be able to provide assistance. 1258

The Food and Drug Administration released updated safety standards Tuesday for makers of COVID-19 vaccines despite efforts by the White House to block them, clearing the way for requirements that are widely expected to prevent the introduction of a vaccine before Election Day.In the new guidelines posted on its website, the FDA said vaccine makers should follow trial participants for at least two months to rule out any major side effects before seeking emergency approval. That standard had been a sticking point between the FDA and White House officials, who said it could unreasonably delay the availability of COVID-19 vaccines.President Donald Trump has repeatedly insisted a vaccine could be authorized before Nov. 3, even though top government scientists working on the effort have said that timeline is very unlikely. On Monday Trump said vaccines are coming “momentarily,” in a video recorded after he returned to the White House.Former FDA officials have warned that public perception that a vaccine was being rushed out for political reasons could derail efforts to vaccinate millions of Americans.A senior administration official confirmed Monday that the White House had blocked FDA’s plans to formally publish the safety guidelines based on the two-month data requirement, arguing there was “no clinical or medical reason” for it.But on Tuesday, the FDA posted the guidance on its website, making clear that regulators plan to impose the safety standards for any vaccine seeking an expedited path to market.FDA Commissioner Stephen Hahn said in a statement that he hoped the guidelines would help “the public understand our science-based decision-making process that assures vaccine quality, safety and efficacy.”The requirements are aimed at companies seeking rapid approval through the FDA’s emergency authorization pathway. That accelerated process, reserved for health emergencies, allows medical products onto the market based on a lower bar than traditional FDA approval. But FDA has made clear only vaccines that are shown to be safe and effective will be authorized for coronavirus.Former FDA acting commissioner Dr. Stephen Ostroff said the requirements seem reasonable given the agency is in largely “uncharted territory” in terms of considering emergency use of a vaccine. The agency has only previously cleared one vaccine through the method — a decades-old shot that was authorized to prevent anthrax poisoning in 2005.“There really is no margin for error here,” Ostroff said. “Even when you’re talking about limited use of a vaccine there has to be some level of assurance that there isn’t a risk here that would far outweigh the benefit.”Dr. Peter Marks, the head of FDA’s vaccine division, said Tuesday that the two-month follow-up requirement was chosen to be “something reasonably aggressive, but not too conservative — right in the middle.” He spoke at a symposium organized by Johns Hopkins University.Initial doses of vaccines for emergency use would likely be reserved for medical workers and people with health conditions that make them particularly vulnerable to coronavirus. Full FDA approval for the general population will require significantly more data and is not expected until mid-2021.The White House attempt to block the guidance followed a string of instances in which the Trump administration has undercut its own medical experts working to combat the pandemic. FDA’s Hahn has been attempting to shore up public confidence in the vaccine review process for weeks, vowing that career scientists, not politicians, will decide if the shots are safe and effective.Pfizer CEO Albert Bourla has stoked excitement by saying that he expects data on whether the company’s candidate works to be ready in late October. But a number of variables would still have to align for the company to submit, and the FDA to review and greenlight, a vaccine application before Nov. 3. Pfizer’s competitors Moderna, AstraZeneca and Johnson & Johnson are working on longer research timelines.Vaccine development typically takes years, but the U.S. government has invested billions in efforts to accelerate the process and help multiple drugmakers prepare multiple candidates. All the doses will be purchased by the federal government for use vaccinating the U.S. population.Beyond exposing the rift between the White House and FDA, the delay in releasing the guidelines may have had limited practical effect.FDA scientists have been discussing the guidelines publicly for weeks and have made clear that the recommendations have already been shared with each of the vaccine developers.Former FDA Commissioner Scott Gottlieb said Tuesday that drugmakers depend on the FDA’s science-based endorsement to vouch for the safety and effectiveness of their products.“I can’t imagine a circumstance where a sponsor would challenge or seek to undermine the FDA’s role here,” Gottlieb said at the COVID-19 symposium. “This is precisely the moment when we need an objective, neutral arbiter.”Last week, Gottlieb and six other former FDA commissioners blasted the Trump administration for “undermining the credibility” of the agency in a op-ed calling for the release of the then-stalled vaccine guidelines.“Scientists should make decisions based on data, unfettered by political pressure or the intrusions of ideology or vested interests,” the officials wrote.___AP Medical Writer Lauran Neergaard contributed to this report.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

The founder of the Women's March is calling for the movement's current co-chairs to step down for allowing bigotry into their mission.Teresa Shook, a lawyer and educator who founded the Women's March movement, accused the group's current co-chairs -- Bob Bland, Tamika Mallory, Linda Sarsour and Carmen Perez -- of associating with bigoted outside groups and tarnishing the Women's March's initial goals in a post on her Facebook page Monday.The co-chairs "have steered the Movement away from its true course. I have waited, hoping they would right the ship," Shook wrote. "But they have not. In opposition to our Unity Principles, they have allowed anti-Semitism, anti-LBGTQIA sentiment and hateful, racist rhetoric to become a part of the platform by their refusal to separate themselves from groups that espouse these racist, hateful beliefs.""I call for the current Co-Chairs to step down and to let others lead who can restore faith in the Movement and its original intent," Shook added. "I stand in Solidarity with all the Sister March Organizations, to bring the Movement back to its authentic purpose."The Women's March leaders swiftly shot back, crediting Shook for "creating a Facebook event named the Million Women's March" and lambasting her for not working to support the movement's ongoing growth."Today, Teresa Shook weighed in, irresponsibly, as have other organizations attempting in this moment to take advantage of our growing pains to try and fracture our network," the Women's March wrote in a post on its Facebook page. "Groups that have benefited from our work but refuse to organize in accordance with our Unity Principles clearly have no interest in building the world our principles envision. They have not done the work to mobilize women from diverse backgrounds across the nation.""Our ongoing work speaks for itself. That's our focus, not armchair critiques from those who want to take credit for our labor," the statement continued.The 2019 Women's March is slated for January, two years after the initial march that followed President Donald Trump's inauguration, and inspired countless sister marches nationwide.Shook's critique comes following longstanding criticism of the group's association with Louis Farrakhan, the leader of the black nationalist group Nation of Islam, who has made numerous anti-Semitic and homophobic comments.Mallory and Perez have both posted photos on Instagram of themselves with Farrakhan praising the National of Islam leader, and Sarsour spoke at the Justice or Else rally headlined by Farrakhan in 2015. Mallory, an African-American leader of the Women's March and anti-gun violence activist, attended a large event in February where Farrakhan stated that "the powerful Jews are my enemy."Mallory declined to denounce Farrakhan after the event. The Women's March released a statement emphasizing that Farrakhan's statements were "not aligned with the Women's March Unity Principles" and that "our external silence has been because we are holding these conversations and are trying to intentionally break the cycles that pit our communities against each other."Sarsour said that following the shooting at the Tree of Life synagogue in Pittsburgh, critics suddenly called on the Women's March to denounce Farrakhan."There was nothing new that happened between Women's March and the Minister," Sarsour wrote in an online essay. "Folks decided to rehash 8 months ago."MPower Change, a Muslim organization that Sarsour co-founded, helped raise over 0,000 to cover the funeral expenses for the Tree of Life victims"This is not a letter in defense of Minister Farrakhan," she added. "He can do that for himself. We have been CRYSTAL CLEAR in BOTH of our statements that we REJECT antisemitism and all forms of racism. We have been CLEAR that Minister Farrakhan has said hateful and hurtful things and that he does not align with our Unity Principles of the Women's March that were created by Women of Color."A week before the Tree of Life shooting, Farrakhan made public anti-Semitic remarks, saying, "I'm not an anti-Semite. I'm anti-Termite." 4113
