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

There is a nationwide voluntary recall of almost 19,000 bottles of hand sanitizer over concerns the mixture contains methanol.The Food and Drug Administration announced Monday the company ITECH361 is recalling their All Clean Hand Sanitizer, Moisturizer and Disinfectant sold in one liter bottles. The 18,940 recalled bottles have UPC Code 628055370130.According to the FDA, substantial exposure to methanol (wood alcohol) can cause nausea, vomiting, headache, blurred vision, and more serious conditions including death. There are no reports at this time of anyone getting sick from the recalled sanitizer.This may sound familiar.

Retailers are encouraged to pull it from their shelves, those who purchased it are asked to stop using it and return the product for a refund.Consumers with questions regarding this recall can contact Corina Enriquez by phone number (888)405-4442 or e-mail at corina@itech361.com, Monday through Friday beginning July 6, 9:00a.m. to 5:00 p.m. (MDT).

This election season, Demetrius Short is hustling to get his people to the polls.“We have the wonderful opportunity as African American men to be here today,” Short said to a group of young African American voters outside a polling site in Nashville, Tennessee. “The next John Lewis might be right here.”Short is the founder and CEO of the Transformation Life Center and Steps of Success 5K, nonprofits mentoring youth living in underserved communities. Now, Short and his team are using physical fitness to inspire political change by leading young Black men on runs and talking about becoming better people afterwards.“Going out, taking your niece and nephew that may not have a father, being that father or mother example to them and just be the change you want to see,” Short said.During this presidential election, Short is reaching out to college students from Fisk University, a private historically Black college in Nashville.“We’re here to come out here and inspire change in our community and inspire young people to really vote,” said Myles Harris, a recent Fisk University graduate.Harris says he is motivated to get more members of African American communities to have their voices heard and their votes counted.“A lot of people don’t vote because they don’t see the point, they don’t understand why it’s so important,” he said.Many members in the local African American community do understand the importance of this election and are calling this political movement inspiring.“Us Black folks are still fighting. It’s time for a change, man,” said Norman T. Wilson. “So, it’s good that they are trying to get them to vote. votes matter, whoever they vote for.”According to the Pew Research Center, the Black voter turnout rate declined in 2016, falling to 59.6% after reaching a record-high 66.6% in 2012.That’s a trend Short wants to change, not by swaying young people’s votes, but through politics, one step and one vote at a time“We don’t have to riot. We don’t have to do it the bad way,” he said. “We can go to the polls and we can do it the democratic way. The way that our country, I believe our country was set up to do."Editor's note: A previous version of this story erroneously said "African Africans" in the headline instead of Africans Americans. It has since been corrected. 2310
