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. By taking frequent samples the researchers discovered that the peak viral load was reached three days after the monkeys were infected.
