Read the following passage carefully and answer the given questions.

Vaccination of children over 12 years of age has been allowed in some countries, but the pandemic’s course has remained unpredictable. In Israel, one of the most vaccinated countries with an estimated 78% coverage of the over-12 population, the Delta variant swiftly caused a spike in infects as distancing norms, the mask mandate and travel bans were eliminated. In one instance, an entire class of students was infected by one unvaccinated child who had been on vacation. This cautionary tale serves to emphasize the importance of priority vaccination of children, starting with those who may have other health conditions, maintaining safety protocols, and adopting low-cost non-pharmaceutical interventions such as good classroom ventilation and open-air instruction wherever feasible. Credentialed studies in the U.S indicate that these are effective measures, along with vaccination. It is vitally important for the Centre to share information on the school reopening experience with all States and issue alerts in real time to enable decision-making. An empirical approach will also enable organizations such as the National Institute of Disaster Management collate useful insights. Parents must be convinced by transparent official measures that the health and education prospects of their children are in safe hands.
