Moderna to work for children coronavirus vaccine

The drugmaker Moderna said on Wednesday that it might soon begin testing its coronavirus vaccine in children aged 12 years through 17 years. The study is to incorporate 3,000 children, with one-half receiving two shots of vaccine 4 weeks apart, and one-half getting placebo shots of salt water.

The study isn’t yet recruiting, and Colleen Hussey, a spokeswoman for Moderna, said it’s not certain when the testing sites are going to be listed or start accepting volunteers. No vaccine are often widely given to children until it’s been tested in them. Moderna’s vaccine has not yet been studied in children or pregnant women. within the new clinical test in adolescents, girls past puberty are going to be tested before each injection to form sure they’re not pregnant.

Children have more active immune systems than adults, and should have stronger reactions, including more fever, muscle and joint aches, and fatigue, said William Schaffner, MD, an communicable disease specialist at Vanderbilt University and an adviser on vaccines to CDC. Paul Offit, MD, a vaccine expert at Children’s Hospital of Philadelphia, said that vaccines “for the foremost part” work equally well in children and adults. Occasionally, different doses are required, he said. Moderna will study an equivalent dose in children that it’s tested in adults.
