Children ages 5 to 12 years old are being recruited in the U.K. for Phase II and Phase III COVID-19 vaccine clinical trials. The vaccine is being fast-tracked even though there are gaps in scientific knowledge about the origin of the new coronavirus and the way it infects and causes disease.
Persons aged 56 to 69, and those over 70 have also been added to the clinical trials to allow researchers to assess how these cohorts’ immune systems respond to the vaccine. One problem with small, quick clinical trials like this is that vaccine adverse reactions often don’t get noticed until after the vaccine is offered to the public, according to Shamez Ladhani, a pediatric infectious disease consultant at St. George’s Hospital in London, and consultant epidemiologist for Public Health England.
