Immunological imprinting is another road block added to the many obstacles and side effects, including some very serious including deaths), concerning the effectiveness and safety of the modRNA based Covid-19 vaccines. Together, they make it highly unethical and difficult to support/ promote the widespread vaccination of children and adults with these vaccines.
