Doctors' opinions on the reason for the 4th wave of COVID-19 in South Korea 2021

According to a survey conducted amongst doctors in 2021, around 28.4 percent of respondents stated that an imbalance of vaccine supply and demand was a reason for the fourth wave of coronavirus (COVID-19) in South Korea. South Korea began buying vaccines later than many other countries, and subsequently struggled to keep up with the demand, leading to initial slow rollout and low vaccination rates. Relaxed guidelines despite the spread of mutated strains, such as the delta variant, and societal expectations for the pandemic to end were also commonly given as reasons. The fourth wave of COVID-19 in South Korea began in July 2021.
