CORONAVIRUS RESEARCH HIGHLIGHTS: 1-MINUTE READS
Vaccine shields monkeys from lung damage
An experimental vaccine from a US–UK team protected monkeys from pneumonia and prompted a strong immune response in the animals. Researchers injected six rhesus macaques (Macaca mulatta) with the vaccine before giving the animals high doses of virus. All vaccinated monkeys developed neutralizing antibodies — which can prevent a virus from entering cells — against SARS-CoV-2. Two of the three control monkeys developed pneumonia; none of the vaccinated monkeys did.

‘Superspread’ at a choir practice infects dozens
A single ill person who attended a choir practice in Washington State led to the probable infection of more than 50 choir members, including 2 who died. This superspreading event emphasizes the importance of avoiding crowds and close interactions to keep the virus at bay, the authors say.

Youngest children are most likely to enter hospital
Children with COVID-19 are at a lower risk of death than are adults with the disease, according to the largest study of infected children in Europe. Researchers analysed data from children under the age of 18 who turned up at hospitals and clinics with COVID-19 symptoms. All 168 who tested positive for the coronavirus recovered fully. Nearly 80% of infants under the age of one were hospitalized, compared with 53% of those between the ages of 11 and 17 (the overall hospitalization rate for infected children in Italy is much lower — around 4%). Two-thirds of the children had at least one infected parent, whose symptoms often appeared before the child’s did.
