Monkeys Infected with Novel Coronavirus Developed Short-Term Immunity
Test monkeys infected with the novel coronavirus responsible for the COVID-19 pandemic were protected from reinfection for up to 28 days later, a Chinese study out Thursday in the journal Science said. While the monkeys displayed initial immunity, it’s unclear how long such immunity will last in humans – it will be necessary to wait months, or even years, to know if the millions of people infected at the start of the pandemic are protected from re-infection. Scientists from Peking Union Medical College performed an experiment on rhesus macaques, often used because of their similarities to humans, to find out if they have a short-term immunity to the virus. Six rhesus macaques were infected in their trachea with a dose of the SARS-CoV-2 virus. They developed mild to moderate symptoms, and took about two weeks to recover.

A Chinese study found that asymptomatic individuals have less antibodies than symptomatic ones, a fact that could have significant bearing on vaccines.

Yet these orders contained no guidance on how to protect essential workers who are at increased risk for poor outcomes because of advanced age or chronic conditions.
