At the beginning of the COVID-19 pandemic, Vietnam was considered one of the most vulnerable countries to the pandemic crisis due to its long border with other countries, especially China, dense population, and limited medical infrastructure. Yet, with a national response plan consisting of strict anti-epidemic measures being timely introduced and rigorous early implementation, Vietnam has managed to keep the number of cases at just over 1,500 among a population of ~100 million people at the end of 2020, second among the countries with the most effective response to the pandemic (1).
As new strains of the virus [including Delta variant B.1.617 and Alpha variant B.1.1.7 with 50–70% higher transmission capacity compared to the original strain (2)] continue to emerge and threaten even the countries with a high percentage of people being vaccinated, the challenges posed for Vietnam as the fourth wave of COVID-19 are much greater than before. Instead of mostly isolated cases as in 2020, the current reemergence of COVID-19 involves cases escalating in number at a pace never seen before, forming large clusters that spread quickly from district to district, then city to city. One of the main case clusters in the current wave of COVID-19 in Vietnam is found in industrial zones, where workers crowded in poorly ventilated factories, canteens, and living quarters near their factories. The rapid level of spread is demonstrated at Hosiden Bac Giang Company, with nearly 1,000 infected workers out of 4,800 (3). Another rapidly expanding cluster of cases involves a religious group meeting that draws a large number of participants, resulting in an outbreak that spread quickly into the community, resulting in a partial lockdown of Ho Chi Minh City and a number of provinces. These clusters pose a significant challenge to the government in terms of activity control, tracing, zoning, and isolating work. With nearly 65% of COVID-19 identified cases in the fourth wave have no clinical symptoms in the first 10 days (10), it is difficult to detect positive cases based on screening, making it more likely to occur outbreaks in the surrounding community (10).
Vietnam has made major adjustments across a variety of sectors in response to the fourth wave, as the population and virus strains have changed. Table 1 outlines and compares the variations in each reemergence's characteristics and policies implemented by Vietnam.

Vietnam has significantly increased its testing capacity and immunization coverage during the fourth outbreak. Following the efforts during the third wave to improve testing, the Ministry of Health continues to allow 10–16 samples to be pooled in one test. It is confirmed that combining many samples in one test is completely feasible and accurate with high sensitivity and specificity (11). This method also enables health workers to test more individuals with the same amount of resources (11), allowing the Ministry of Health to promote testing at optimal costs. From April 29th to June 1st, 1,374,503 samples have been tested for a total of 2,703,103 people (12). The testing capacity at hospitals has gone up by 1.7 times compared to the peak of the second epidemic (13).
In early March, nationwide training for health workers was set up to organize the COVID-19 vaccination campaign (14). Nearly 23% of the population over the age of 18 had received at least one dose of vaccine by August 30th (15), with a normal response rate of about 30% after vaccination, lower than the report (16). According to the plan, Vietnam will vaccinate 75 million people in 2021, making it the largest vaccination campaign ever (17).
Maintaining present measures, particularly stakeholders engagement and community mobilization, are critical in the fight against COVID-19. While the military has been in charge of managing the isolation centers from the beginning of the pandemic, the interdisciplinary task force set up contacts tracing to stop community spread. The media agencies were constantly updating information about the pandemic situation to the public. Although Vietnam has only 98 million people, social platforms have sent ~20 billion warning messages about measures to prevent epidemics. It is also vital to maintain introducing social security packages in these challenging times, which had a profound impact by supporting people, enterprises, and organizations to survive, especially in the time of social isolation (18).
Disease control criteria must remain fundamental, and it is up to each locality to develop adaptation plans to the outbreak. Some provinces can continue to isolate F0 from the community, others combine quarantines in a narrow area with an increase in vaccination rates. For the COVID-19 pandemic, ministries, branches, and local governments must have explicit and detailed instructions for implementation and control (19). Moreover, strategies must be flexible and adapt to each wave of the pandemic.
