How protected are we against Covid-19? Scientists search for a test to measure immunity
CNN
As mask mandates are lifted and restrictions removed in a step towards normalcy, having a test that could measure immunity would be a powerful tool to assess individual risk.
"I am on immunosuppressants that make me more vulnerable for serious Covid complications," said Sobieck, 37, who lives in Minnesota. "If you're immunocompromised, you may not have a very good response to the [Covid-19] vaccine."
Seeking evidence that his immune system was working the way it should, Sobieck made an unusual request: He asked his nephrologist to do a blood test that gives a rough measure of antibodies, a type of protein the body creates in response to an infection or vaccine. Antibody titers reveal the concentration of a specific antibody found in someone's blood.

The White House is making clear it views President Donald Trump’s Friday Oval Office showdown with Ukrainian President Volodymyr Zelensky as an overwhelming win underscoring Trump’s “America First” leadership, dispatching top officials and allies on the airwaves to amplify Trump’s handling of the situation even as European leaders are putting on a key show of force of unity for Ukraine and its leader.
