FDA scientists have given their stamp of approval and said that Johnson & Johnson’s vaccine is safe and effective in fighting Covid-19. This could lead to its emergency-use authorization very soon. The vaccine reduced moderate to severe cases by 66%, does not require cold storage and is most importantly only a single shot. Matthew Herper, senior writer at STAT News, joins us for more on the J&J vaccine which can also help protect against new variants.

Next, the latest Gallup poll shows that adults who identify as LGBTQ has risen about one percentage point since the last update we got in 2017. 5.6% of adults identify this way with 1 in 6 adults in Generation Z considering themselves LGBTQ. The majority of LGBT Americans also say they are bisexual. Jeffrey Jones, senior editor at Gallup, joins us for more.

Finally, a team of scientists with the WHO are exploring the origins of Covid-19 and are focusing on two animal types for possible vectors where the illness jumped to humans. Investigators say that ferret badgers and rabbits, which were sold at the Wuhan market could have played a role in the spread. Drew Hinshaw, reporter at the WSJ, joins us for more on the WHO investigation into Covid-19.
