The World Health Organization says that children between five and fourteen years old have the highest rate of COVID-19 infections in Europe at the moment.
According to Hans Kluge the WHO's European Director on Tuesday COVID-19 was two to three times higher among young children than the average population in some places.
"This brings me to my triple call today. Number one, to shift from a reactive mode to stabilizing the crisis. Two, to protect children and the schools as part of the response strategy, and three not to mandate without reaching out to the communities first."
Meanwhile, the European Medicines Agency and European Centres for Disease Prevention and Control recommended mix-and-match booster shots 3 to 6 months after primary vaccination.
The ECDC, on its website on Tuesday said the two agencies have "reviewed the available evidence, and provided technical recommendations and advice on heterologous vaccination against COVID-19, either in the primary course or as a booster."
It added that it showed better results when mixing virus vector vaccines such as ones made by AstraZeneca or Janssen with mRNA vaccines such as Pfizer's or Moderna's.
Mixing two types of mRNA vaccines has not been well studied enough to know the safety and efficacy levels BUT it has been studied enough to indicate that such an approach could be used when flexibility or acceleration in the vaccination campaigns is needed under the shortage of supplies.
