evidence: Here’s the real deal on how risks of the COVID-19 vaccine for children stack up against risks of the disease itself, according to Drs. Chang and Aggarwal. [...] More than 9.6 million eligible children have received at least one dose of a COVID-19 vaccine and 7.1 million of those are fully vaccinated, reports the U.S. Centers for Disease Control and Prevention (CDC). Those under 12 years old cannot yet be vaccinated. [...] Other children with COVID-19 may suffer long-term cardiovascular repercussions, including heart failure and potentially deadly blood clots, he says.
