Imagine if wealthy nations gave out 50% of their stockpile of COVID-19 vaccines.

In light of these findings, the wealthier countries who have been
stockpiling COVID-19 vaccines are being sent a strong warning. While this
may help in the short term, it makes everyone more susceptible to illness
in the long run.
Across a five-year scenario, scientists found that when rich countries
handed away 46 percent of their COVID-19 vaccine supply to low and
middle-income countries (LMICs), it not only lowered the death rate in
those countries but also reduced the probability of new virus strains
appearing.
