AbstractBangladesh is located in Southeast Asia that has a high population density. It is a lower‐middle‐income country. The COVID‐19 pandemic severely impacted the nation that slowed its economic growth. It halted major industries, crippling the nation's economy. The students were uncertain after the declaration of school closures. Hospitals could not treat other patients properly due to the vast health burden of COVID‐19. Bangladesh put up a solid fight during COVID‐19 as a lower‐middle‐income country. Prompt action, early vaccination drives, effective awareness campaigns, and widespread public involvement have enabled Bangladesh to bring more than 90% of its population into COVID‐19 vaccination coverage. It was possible by the effective diplomatic and local health strategy implemented by the Bangladeshi government, the country's extensive prior experience, and its long history of achieving a high success rate in other vaccination campaigns. Bangladesh was able to flatten the curve sooner than other developed countries. Therefore, the cogs of everyday social life and the economy begin to turn once more. The strategy Bangladesh used to combat the COVID‐19 pandemic through vaccination and diplomatic policy by calling on its prior experience has the potential to serve as a model for other low‐ and middle‐income countries and an example for developed nations.
