In April, during the height of the coronavirus lockdown, Trump administration health experts hailed a test that would confirm if someone had already had the virus and therefore couldn’t get sick again. The antibody test would show who might have “the wonderful, beautiful immunity,” President Donald Trump said was needed to get the nation working again. Months later, the tests exist but haven’t fulfilled their promise of allowing Americans to reclaim their lives, said Dr. Jennifer Rakeman of New York City’s Public Health Laboratory. In fighting off the virus, the body makes antibodies, which the tests measure. Unfortunately, scientists are still figuring out how well and for how long antibodies provide the immunity that protects against another infection by the coronavirus.

Long-term human or animal studies are usually needed to reach answers about immunity. Much of that work is done by the National Institutes of Health and universities, but they are occupied developing a vaccine against the coronavirus. Until more is known, antibody tests should not be used to determine when it is safe to return to work or school, says the Centers for Disease Control and Prevention and the American Medical Association. But the tests are useful in large studies to see how widely the coronavirus has spread and to screen people who have recovered and could donate their blood plasma for use as a treatment for those in the throes of COVID-19, the disease caused by the coronavirus.

Morrison said Monday that CSL will manufacture that vaccine as well for distribution in Australia, and that he expects 3.8 million doses to be available in January or February 2021. Israel is beginning partial nighttime lockdowns in 40 cities and towns with the country’s highest infection rates. Schools in those areas will also be closed, and gatherings will be limited to 10 people inside and 20 outdoors. “I know that these restrictions are not easy but in the current situation there is no avoiding them,” Prime Minister Benjamin Netanyahu said in a statement.
