Investigadores de los Centros para el Control y la Prevención de Enfermedades (CDC), tras revisar los datos nacionales sobre tasas de inmunización correspondientes a más de 16.000 menores, revelan que la mayoría de niños de 2 años de edad no han recibido en el momento adecuado alguna de las vacunas recomendadas por las autoridades sanitarias.
Los autores señalan que vacunar a los niños antes de tiempo puede suponer una pérdida de efectividad, mientras que vacunarlos más tarde implica un período de tiempo en que se encuentran desprotegidos frente a la enfermedad.
