The measles outbreak in Bangladesh has led to significant health challenges, prompting the government to respond with a new vaccination campaign aimed at reaching 3.4 million children previously missed. This comes amid ongoing scrutiny regarding the effectiveness of public health measures given that first-dose vaccination coverage has dropped to 90% and second-dose coverage to 86%, below the 95% threshold needed for herd immunity, reports BritPanorama.
In the wake of political upheaval that saw Prime Minister Sheikh Hasina ousted, health workers went on strike, causing delays in vaccine orders and disrupting routine immunization programs. These disruptions have raised concerns over the quality and accuracy of vaccination data, with reports indicating inaccuracies as high as exceeding 100% of those targeted.
An emergency vaccination initiative with an initial uptake of almost 20 million children led to a temporary decline in new measles cases. However, deficiencies in the program quickly emerged, revealing that the outreach had not covered all children in the intended age group, highlighting a gap in the immunization strategy.
Prime ministerial adviser Hyder acknowledged these gaps on September 14, attributing rising cases to vaccine hesitancy and parental neglect. Additionally, documents detailing government meetings with the World Health Organization (WHO) outlined how the hastily launched vaccination program may have overlooked essential readiness checks.
Emergency program missed millions
Despite an apparent initial victory against measles, the reality proved different as it became clear that not all districts were adequately prepared for vaccination efforts. Preparatory checks were reduced from the typical four rounds to one due to time constraints, which likely contributed to the shortcomings observed during the campaign.
Professor Mahmudur Rahman, an epidemiologist in Bangladesh, warned that lacking thorough preparedness often results in the most vulnerable populations—particularly low-income and hard-to-reach children—missing out on essential vaccinations. The urgency of the campaign’s launch left little time for strategic planning, as noted by former immunization chief Tajul Islam Abdul Bari, who emphasized that vaccination drives usually require extensive preparation.
By August, it was evident that coverage gaps persisted, with a report stating that the proportion of unvaccinated children among confirmed measles cases remained alarmingly high. WHO’s deputy representative in Bangladesh, Dr. Rajesh Narwal, reinforced the need for a more resilient and effective routine immunization program moving forward.
In Sylhet, where reports indicate 180 children have succumbed to measles, many families reported a lack of health worker outreach prior to these tragic occurrences. In late September, the government launched a new campaign to address this, promising community involvement to ensure no child is left unvaccinated.
Reaching every child, however, presents ongoing challenges, not least of which is an estimated 40% of children going unregistered. Compounding these issues, nearly a third of health worker positions remain unfilled, while there are calls for extending vaccination efforts to include older children, who account for a significant portion of the current measles cases.
Scientific inquiries are also under way to understand why children’s immunity is diminishing more rapidly than expected, presenting another layer in a complex public health scenario. Adding to the urgency is the concurrent fight against a dengue epidemic, straining resources and healthcare facilities throughout the nation.
At a local hospital dealing with the measles crisis, capacity challenges are already evident, complicating what is an already fraught health landscape.
