What do we know about Covid-19 vaccines in under 5s?

How researchers and public health officials perceive the risk-benefit ratio of rolling out vaccines to under 5s varies around the world and depends on the impact covid-19 has had on that country. Sweden has had just a handful of fatalities in those aged under 18,6 and vaccines are still not available to children aged 5-11 years. But in Brazil the virus has killed an average of two children under the age of 5 each day7—a rate which equates to around one in every five deaths among under 5s worldwide. Understandably, doctors are keen to boost protection levels, fearful of the impact that future variants might have.
