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 fourth nor'easter in three weeks already is closing schools and canceling thousands of flights Wednesday as it's expected to dump record springtime snow in the Northeast.A day after the official beginning of spring, the storm will bring heavy snow, strong winds and even coastal flooding to some areas. It has potential to be one of the most significant and most disruptive snowstorms this late in the season, CNN meteorologists said."If the current forecast pans out, this nor'easter will dump more snow on Washington, Philadelphia and New York than the three earlier storms combined," CNN meteorologist Brandon Miller said.More than 70 million people are under a winter storm watch, warning or advisory from the southern Appalachians to Boston.The storm will move away from the region by Thursday but not without first hitting coastal New England and Maine.Latest developments? More than 4,100 flights are canceled Wednesday due to the storm, according to the tracking site Flightaware.com.? Public schools in New York City, Philadelphia and the District of Columbia are closed Wednesday.? The storm already dumped 13 inches of snow in Greencastle, Pennsylvania, and blanketed Smith Crossroads in West Virginia with 9.2 inches.Snow disrupting nation's capitalWashington will likely see 4 to 6 inches of snow, with some models hinting at much higher totals for the District. Areas west and north of the city are likely to see close to a foot of snow."It's been 75 years since Washington has had 5 inches of snowfall or greater this late in the season," Miller says.Track the storm with high resolution auto-updating graphicsThe inclement weather caused closures for much of the federal government. The White House and State Department canceled all public events for the day. However, the House and Senate are planning to work Wednesday as Congress tries to finalize a spending deal.Philadelphia could see up to a foot of snow. The City of Brotherly Love may get its biggest snowfall after the first day of spring in more than 100 years.For those in other parts of Pennsylvania, the storm was already well underway Wednesday morning. Thile Kreider posted an Instagram video of the snow blanketing her yard in Manheim.New York could break 1958 recordWind gusts and snow reached New Jersey and New York City on Wednesday morning. Ten inches to more than a foot is forecast in the New York City area before the storm departs early Thursday.But Central Park in Manhattan may only receive 4 to 6 inches of snow, CNN meteorologist Chad Myers said, explaining it's more likely snow will accumulate in areas at higher elevations."If New York gets 12 inches of snow -- the National Weather Service currently has a high-end potential of 13 to 21 inches -- it would be its largest snowfall ever recorded after the first day of spring," Miller says.The current record is 11.8 inches, set on March 21, 1958.With these late winter storms, it is difficult to predict snowfall amounts because of the mixing of warmer air. In some of the earlier nor'easters, the air near the ground has stayed warm enough that places like New York have seen lots of snow fall from the sky but had little accumulation. An urban heat island effect is plausible once again with this spring storm.Boston stayed on the warmer side in the first two nor'easters but then got walloped with snow during the third storm this month. The city is likely to see another 6 to 8 inches of snow, adding to the 20-plus inches it has already received in March.If Boston gets 10 inches, the city would have its third snowiest March on record.These late winter storms are likely to become more frequent with climate change. A study last week in the scientific journal Nature Communications ties extreme winter weather, specifically major snowstorms in the Northeast, to warming Arctic temperatures.Blizzard conditions likelyWith a forecast of heavy snow and winds more than 45 mph, blizzard conditions are possible.New York City could see sustained winds of 20 to 30 mph Wednesday, and coastal areas such as Cape Cod in Massachusetts are predicted to receive gusts up to 60 mph from midmorning Wednesday to Thursday.What is makes a snow storm a blizzardFlooding is a threat along the coast from Virginia to Massachusetts. Some of the worst coastal flooding could occur along the Jersey Shore, with high tides of 2 to 3 feet above normal possible.This will put a strain on already vulnerable coastal areas, which saw dramatic storm surges from the nor'easters over the last three weeks.The-CNN-Wire 4555

The European Union is to propose ending twice-yearly clock changes after a large-scale public survey, European Commission President Jean-Claude Juncker said Friday.According to Juncker, more than 80% of EU citizens want to abolish daylight saving time and instead remain on the time used during summer instead.At the moment, each EU member state puts clocks forward one hour on the last Sunday of March and back again on the last Sunday in October."This debate about summertime, wintertime has been around for many years here," Juncker told German broadcaster ZDF."Many people are contributing to this debate. We did a survey, a public survey. Millions responded and think that in the future we should have summertime all year round. So that's what will happen.""The people want this; we will do this," he said.For any change to go into effect, legislation must be drafted and win approval from the 28 member nations and the European Parliament.One of the chief critics of daylight saving time has been Finland, which has one of the most northerly capital cities in the EU.Over 70,000 Finns signed a petition last October to urge the government to move away from daylight saving time.For Finland, the plan is also complicated by the fact it shares borders with non-EU states Russia, Belarus and Ukraine, all of which scrapped daylight saving time in 2011.Those in favor of the time change say the extra light in the morning during standard time and and additional evening light in summer can help prevent road accidents.The-CNN-Wire 1540

The good news is Americans are getting COVID-19 test results back, on average, a day faster than they were over the summer. The troubling news, according to experts, is that it is still taking three days on average for Americans to find out their COVID-19 status and this is not quick enough to help with contact tracing and quarantine efforts to slow the spread.Researchers from several universities, including Harvard, Northeastern, Northwestern and Rutgers universities, have been collecting data and conducting surveys for months since the beginning of the coronavirus pandemic.“Prompt test results constitute the foundation of a successful COVID-19 containment strategy,” researchers state at the beginning of their paper.Data now shows, of the participants who got a test for the coronavirus in late September, the average wait time was 2.7 days.In early August, the group announced their survey data showed the average wait time nationwide was 4.1 days. More than 30 percent of participants reported, at the time, they didn’t get test results back until four days or longer.The percentage of people getting results within 24 hours is also increasing; the September survey showed 37 percent of people getting results back in one day, compared to 23 percent over the summer.“Rapid turnaround of testing for COVID-19 infection is essential to containing the pandemic. Ideally, test results would be available the same day. Our findings indicate that the United States is not currently performing testing with nearly enough speed,” researchers said.Disparities still exist for Americans who are Black or Hispanic. Although wait times are shorter for these groups as well compared to summer numbers, they are still, on average, a day or more longer than white test takers.In the latest survey, Black Americans reported waiting an average of 4.4 days for results, and Hispanics reported waiting 4.1 days. By comparison, white and Asian Americans reported wait times of 3.5 and 3.6 days on average, respectively.Also troubling for trying to control the spread of the coronavirus, the data shows how many of those who tested positive had some sort of conversation about contact tracing.“Only 56% of respondents who received a positive COVID-19 test say that they were contacted for the purpose of contact tracing,” the survey found.The survey talked to more than 52,000 people across all 50 states and the District of Columbia. 2434
