Paragraph: "Gov. Rick Perry marked the 38th anniversary of what he called ""the tragedy"" of the U.S. Supreme Court's landmark Roe v. Wade decision by speaking to fellow abortion opponents at the Jan. 22 Texas Rally for Life outside the Capitol building. Perry said that since the 1973 decision, which established abortion as a constitutional right, ""50 million, 50 million children have lost their chances. That is a catastrophic number."" PolitiFact Texas readers asked us to check Perry's statement. But before diving in, we noted two issues with Perry's use of ""children"" -- a flash point in the political, moral and scientific national debate over abortion. One, abortion rights supporters dispute calling unborn fetuses ""children."" Second, an unknown share of the 50 million aborted pregnancies referenced by Perry would not have resulted in live children, due to the natural risk of miscarriages and stillbirths. For our inquiry, we focused on the number of U.S. abortions since Roe was decided. The Roe v. Wade ruling, issued Jan. 22, 1973, struck down a Texas law prohibiting nearly all abortions and held that the right to privacy ""is broad enough to encompass a woman's decision whether or not to terminate her pregnancy."" It said states could not prohibit a woman from having an abortion before viability, the time at which a fetus can survive outside a woman's body. It noted that viability ""is usually placed at about seven months (28 weeks) but may occur earlier, even at 24 weeks."" After fetal viability, the court said, states could limit abortions provided that their policies met certain requirements, including an exception to protect the life of the woman. Since then, other Supreme Court rulings have affirmed states' rights to approve further restrictions. During the early 1960s, every state except Pennsylvania allowed abortions when needed to protect a woman's life, according to a March 2003 article published by the universally respected Guttmacher Institute, which studies and advocates on issues related to reproductive health. At the time Roe was decided, 17 states allowed abortions in certain other situations such as when pregnancy was the result of rape or incest. In 1972, the year before the Roe ruling, about 587,000 legal abortions were reported to the federal Centers for Disease Control and Prevention, according to a 2005 CDC report. And since 1973? Perry spokeswoman Catherine Frazier pointed us to a January 2010 report from the National Right to Life Committee, a Washington-based group that opposes abortion, that says about 52 million abortions took place from 1973 through 2009. According to the report, the group arrived at the total using figures from the Guttmacher Institute for 1973 through 2005; estimating a number for the next four years; and finally adding 3 percent to account for under-reporting. The National Right to Life publication says 3 percent is the under-reporting rate estimated by Guttmacher. Using a similar methodology, National Right to Life has since updated its numbers. The new report says that more than 53 million abortions took place from 1973 through 2010. Rachel Jones, a senior research associate at Guttmacher, told us the institute doesn't adjust its numbers — which are estimates based on surveys of facilities where abortions are performed, including hospitals and clinics — for under-reporting. She said a 1994 Guttmacher study had found that some small facilities weren't included in the institute's survey, which indicated that the number of abortions in 1992 was actually 3 percent to 4 percent more than reported. Our attempts to reach officials at National Right to Life were unsuccessful. Next, we sought the most up-to-date abortion data from Guttmacher. Spokeswoman Rebecca Wind provided us with a 2011 report that includes annual data on abortions from 1973 through 2008. The total: 49.3 million. We also sought abortion numbers from other sources. Data from the CDC indicate that there were 37.8 million abortions from 1973 through 2006. However, according to the CDC's website, states are not required to report abortion information to the agency, so in some years, the numbers are incomplete. For example, the CDC's 2006 data do not include information on abortions in California, Louisiana or New Hampshire. Representatives of abortion rights organizations Planned Parenthood and NARAL Pro-Choice Texas told us that the Guttmacher Institute is the best source for this information. Summing up: Perry's statement indicating that there have been 50 million abortions in the United States since 1973 appears to be on target. The Guttmacher Institute estimates that there were 49.3 million abortions in the U.S. through 2008 — 700,000 shy of 50 million. Considering that Guttmacher says there were more than 1 million abortions in both 2007 and 2008, it's reasonable to conclude that the United States has reached the 50 million mark." Claim: Rick Perry Says there have been 50 million abortions since Roe v. Wade was decided.

Paragraph: Moncef Slaoui, a former GlaxoSmithKline executive, will lead “Operation Warp Speed,” Trump’s push to accelerate the vaccine development process for COVID-19, according to an administration official. Slaoui is to serve in a volunteer capacity, and will be assisted by Army Gen. Gustave Perna, the commander of United States Army Materiel Command. The move comes as the president and White House aides hope to produce vaccines for the coronavirus faster than what many scientists believe is realistic. The administration is aiming to have 300 million doses to distribute to Americans by the end of the year, believing a reliable vaccine is the only way to promote an economic rebound. “Operation Warp Speed” is operating largely independently of the existing White House coronavirus task force, which is also shifting its focus toward vaccine development. The initiative is being promoted by White House senior adviser Jared Kushner, and involves officials from the Defense Department and the Department of Health and Human Services. On Tuesday, Dr. Anthony Fauci, the government’s top infectious disease expert, said a vaccine would not be available by the beginning of the next academic year. “The idea of having treatments available or a vaccine to facilitate re-entry of students into the fall term would be something that would be a bit of a bridge too far,” he said, “even at the top speed we’re going.” Claim: Trump to name former pharma exec as vaccine czar.

Ex Output:
President Donald Trump is set to name a former pharmaceutical executive to lead his administration’s all-out effort to produce and distribute a coronavirus vaccine by the end of the year.

Paragraph: "Since the mass shooting at Sandy Hook Elementary School in Newtown, Conn., supporters and opponents of gun control have thrown out statistics to support their point of view. Here’s one that caught our eye, offered by liberal commentator Mark Shields on the Dec. 21, 2012, edition of the PBS NewsHour. Shields told host Judy Woodruff, ""You know, Judy, the reality is -- and it's a terrible reality -- since Robert Kennedy died in the Ambassador Hotel on June 4, 1968, more Americans have died from gunfire than died in … all the wars of this country's history, from the Revolutionary through the Civil War, World War I, World War II, in those 43 years. ... I mean, guns are a problem. And I think they still have to be confronted."" Is the death toll that high? Let's examine each half of his comparison. Deaths from warfare  We found a comprehensive study of war-related deaths published by the Congressional Research Service on Feb. 26, 2010, and we supplemented that with data for deaths in Iraq and Afghanistan using the website icasualties.org. Where possible, we’ve used the broadest definition of ""death"" -- that is, all war-related deaths, not just those that occurred in combat. Here’s a summary of deaths by major conflict:  4,435 2,260 13,283 525,000 2,446 116,516 405,399 36,574 58,220 383 2,175 4,486 1,171,177 Another 362 deaths resulted from other conflicts since 1980, such as interventions in Lebanon, Grenada, Panama, Somalia and Haiti, but the number is not large enough to make a difference. Gunfire deaths  The number of deaths from gunfire is a bit more complicated to total. Two Internet-accessible data sets from the Centers for Disease Control and Prevention allow us to pin down the number of deaths from 1981 to 1998 and from 1999 to 2010. We’ve added FBI figures for 2011, and we offer a number for 1968 to 1980 using a conservative estimate of data we found in a graph in this 1994 paper published by the CDC. Here is a summary. The figures below refer to total deaths caused by firearms: We should note that these figures refer to all gun-fire related deaths -- not just homicides, but also suicides and accidental deaths. In 2011, about one-quarter of firearm-related deaths were homicides, according to FBI and CDC data. Using total firearm-related deaths makes the case against guns more dramatic than just using homicides alone. When we rated a previous Facebook post, we lowered an otherwise  claim because it said that ""nearly 100,000 people get shot every year."" We found that the number of gun deaths and non-fatal injuries added up to 104,852, but we concluded that the term ""get shot"" could suggest victims who got shot by someone else rather than by their own hand. We don’t see a similar problem with the way Shields’ comment was phrased -- namely, ""died from gunfire."" Our ruling Since Shields’ comparison was otherwise accurate, with about 1.4 million firearm deaths to 1.2 million in war." Claim: "Since 1968, ""more Americans have died from gunfire than died in … all the wars of this country's history."
