To end the pandemic, there need to be enough people immune to COVID-19 and there are two ways to do that: immunity through infection or from a vaccine."I think racing to herd immunity is the dangerous thing that I’m concerned about," said Dr. Stuart Ray, a professor of medicine at Johns Hopkins University School of Medicine.Herd immunity is when the spread of the infection cannot be sustained because the number of people who are immune is high enough. Some countries are considering it as a strategy to combat COVID-19.But Ray said it could not work in the US unless much more effective treatments are developed.He says on average, a newly infected person infects two others, so to have herd immunity from COVID-19 about 60 percent of people would have to become immune."We would have something like another 100 million people, maybe more, infected. 150 million more and even if the major complication rate is a fraction of 1 percent, we will still have huge numbers of deaths," said Ray.He said we also don’t know if just having had the infection once will create lasting immunity to control the spread."It possible that you could be immune enough not to get sick and still not immune enough to prevent that spread and so herd immunity is a tough bar for us to aim for because not only do we need 60 percent of people to be immune but we need them to be immune in a way that prevents them from infecting other people," said Ray.The other way to achieve herd immunity would be through a vaccine."Vaccines can work better, provide better immunity than the natural infection does. The new shingles vaccine provides great immunity and protects more than 95 percent of people from getting shingles," said Ray.Several vaccines are still going through the last phase of clinical trials to see if any also creates enough immunity to prevent passing the virus along.This story was first reported by Abby Isaacs at WMAR in Baltimore, Maryland. 1946

Toni Braxton's last album was in 2014 and titled "Love, Marriage & Divorce."These days she looks to be more focused on the first two of those.In a tweeted teaser for the sixth season of her family's WE realty series, "Braxton Family Values," the singer shares some news."I have an announcement to make," Braxton says. "I'm engaged!"She then flashes a massive rock.And while Braxton doesn't say who her fiancé is, fans suspect it's rapper and hip-hop mogul Birdman, whom she has reportedly dated for two years.Braxton, 50, and the Cash Money Records co-founder (who is 49) first went public in 2016 with an appearance at the BET Awards.But the pair have tried to keep their relationship under wraps.The reality show focuses on the lives of Braxton, her sisters and their mother.The new season is expected to focus on the relationship between younger sister Tamar Braxton and music executive Vincent Herbert, who married in 2008 and underwent a very public split last year.Tamar Braxton has been pretty chatty about her older sister and Birdman, telling talk-show host Wendy Williams in September that she believed the pair were secretly married.She said Birdman was present with the family when her mother was hospitalized with heart trouble."I think that's my brother-in-law, I do," she said. "I think they eloped. 'Cause he was there in the way like a brother-in-law."Toni Braxton was previously married to musician Keri Lewis for 12 years, and they have two teen sons together. They split in 2013.Braxton's new album, "Sex & Cigarettes," is scheduled to drop in March.CNN has reached out to reps for her and her beau for comment.  1653

There are many questions and few answers after President Donald Trump announced that he and first lady Melania Trump have tested positive for the coronavirus.One thing is for sure: The ripple effects from Trump’s diagnosis are extensive.The president said he and the first lady will isolate following their confirmed positive coronavirus test. That means Trump’s visit to Florida on Friday for a scheduled Make America Great Again rally is off. He was also scheduled for a roundtable with supporters in Washington on Friday. That is now canceled.Only one event now remains on Trump’s schedule for Friday: A phone call on COVID-19 support to vulnerable seniorsAlso, senior Trump aide Hope Hicks is isolating at home after she is confirmed to have the virus. It is unclear if other staffers who were in contact with Hicks and the president have also come down with the virus. Both Trump and Hicks were seen on Wednesday in Marine One in close contact with other staffers including Jared Kushner.With a now confirmed outbreak of the coronavirus inside the White House, a number of senior staffers, Secret Service agents, aides and others may be required to quarantine. How the White House will function with a president in isolation and senior staff in quarantine remains in question.But the president’s physician showed optimism that Trump can continue his duties as president.Dr. Sean Conley said, "Rest assured, I expect the President to continue carrying out his duties without disruption while recovering and I will keep you updated on any future developments."The CDC says that for those with confirmed coronavirus cases, isolation is necessary for 10 to 20 days.“For most persons with COVID-19 illness, isolation and precautions can generally be discontinued 10 days after symptom onset and resolution of fever for at least 24 hours, without the use of fever-reducing medications, and with improvement of other symptoms,” the CDC said. “A limited number of persons with severe illness may produce replication-competent virus beyond 10 days that may warrant extending duration of isolation and precautions for up to 20 days after symptom onset; consider consultation with infection control experts.”There are also questions on how this impacts Joe Biden’s campaign. Biden shared a stage with Trump on Tuesday, and senior staff of both candidates sat in the audience for Tuesday’s debate.Also, questions on what role Vice President Mike Pence will be forced to play in the coming weeks is in question. 2511

There was a “concerning” increase in the number of drug overdoses in the US in from March through May 2020, the Centers for Disease Control and Prevention said on Thursday.The data were part of an annual analysis of drug overdoses in the US. The data went from June 2019 through May 2020. The CDC noted that pre-pandemic drug overdoses were up in the month preceding the pandemic, but increased further when much of the US economy closed to stop the spread of the virus in March.The CDC previously estimated that 19,416 Americans died from drug overdoses from January through March 2020, which was up nearly 3,000 deaths. Approximately 81,230 drug overdose deaths occurred in the United States in the 12-months ending in May 2020, the CDC reported. For the year ending in May, there were nearly 10,000 additional drug overdose deaths compared to the previous year.The CDC said that synthetic opioids, primarily illicitly manufactured fentanyl likely drove the increase. The American Medical Association says that there has been a 37% drop in prescriptions of opioids since 2014.“The increase in overdose deaths is concerning.” said Deb Houry, M.D., M.P.H., director of CDC’s National Center for Injury Prevention and Control. “CDC’s Injury Center continues to help and support communities responding to the evolving overdose crisis. Our priority is to do everything we can to equip people on the ground to save lives in their communities.”The CDC issued a set of recommendations to help combat drug overdoses:Expand distribution and use of naloxone and overdose prevention education.Expand awareness about and access to and availability of treatment for substance use disorders.Intervene early with individuals at highest risk for overdose.Improve detection of overdose outbreaks to facilitate more effective response.The CDC added that “Measures taken at the national, state, and local level to address the COVID-19 pandemic may have unintended consequences for substance use and overdose, but CDC is working with states, territories, tribes, cities, and counties across the country to continue drug overdose surveillance and prevention efforts.”During the same timeframe of March through May 2020, more than 67,000 Americans died from the coronavirus despite intense mitigation efforts, according to Johns Hopkins University data. The death tolls from the coronavirus and drug overdoses show the challenge public health officials face in keeping the country healthy amid a pandemic.“The disruption to daily life due to the COVID-19 pandemic has hit those with substance use disorder hard,” said CDC Director Robert Redfield, M.D. “As we continue the fight to end this pandemic, it’s important to not lose sight of different groups being affected in other ways. We need to take care of people suffering from unintended consequences.” 2842
