The pediatric formulation of the immunizer is of the tenth of that applied to adults. According to preliminary data from Pfizer, the vaccine is innocuous and produces an immune response. However, when verifying that his two-dose scheme turned out to be less effective in preventing Covid-19 among children aged 2 to 5 years, other possibilities began to be studied.

According to AP, the two-dose authorization process could mean that children in this age group would receive the vaccine. more than a month earlier than previous estimates indicated, provided the FDA and the Centers for Disease Control and Prevention give the green light to the request.
