In a recent article titled, “COVID-19 vaccine uptake and vaccine hesitancy in Indian patients with cancer: A questionnaire-based survey,” Noronha et al.[1] demonstrated a high hesitancy rate (59%) toward COVID-19 vaccination among oncologic patients in Mumbai. This finding is consistent with studies conducted in other regions,[2],[3] demonstrating that vaccine hesitancy persists as a critical impediment to prevent severe COVID-19 among cancer patients. Notably, the vaccine acceptance rate reported by Solís Arce et al.[4] among the general population in India (84%) presents a stark contrast. However, the absence of a validated instrument for assessing vaccine hesitancy and the use of a convenience sample by Noronha et al.[1]] limit the direct comparison of the results of these reports.

The most common reasons for not having received a COVID-19 vaccine were fear of its impact on cancer treatment and lack of information. Consequently, the authors recognized that educational campaigns are key to increasing vaccine acceptance. However, two other strategies could further enhance vaccination rates: (1) encouraging oncologists to routinely provide information on COVID-19 vaccines and promote vaccination and (2) implementing a priority program to facilitate access to COVID-19 vaccines among cancer patients at a particularly high risk of presenting severe disease.

Noronha et al.[1] reported that nearly half of the patients who had already received a vaccine against COVID-19 had accepted it based on their physicians' advice. Furthermore, one in four hesitant patients reported that they could be convinced to receive a COVID-19 vaccine if their treating physician recommended it. The importance of healthcare professionals in promoting vaccination has also been discussed in previous reports,[2],[3] and the findings of this study reinforce the need for oncologists to routinely assess for vaccine hesitancy and actively endorse vaccination. Nonetheless, the proportion of healthcare workers who counsel their patients to get vaccinated against COVID-19 has been poorly explored and should be considered an area for future research. Furthermore, addressing vaccine hesitancy among healthcare professionals (estimated to be 19% worldwide[5]) should be considered an urgent priority.

Despite the authors stating that COVID-19 vaccines were widely available for the population studied, a substantial proportion of patients (18%) declared that they had not received a COVID-19 vaccine due to unavailability. Access to COVID-19 vaccines might be inadequate in resource-constrained settings; while it is desirable to give priority to all cancer patients, this might not be feasible. Hence, some countries with a restricted vaccine supply have opted to deny cancer patients a priority status, while others have conceded early vaccine to oncologic patients but report high levels of vaccine unavailability. Hence, it is essential to optimize immunization strategies and prioritize patients according to the risk of severe disease. Among the oncologic population, factors such as age, comorbid diseases, malignancy type, treatment status, and level of immunosuppression may place some patients at a higher risk of infection and severe COVID-19. Thus, if the vaccine supply is limited, some oncologic patients could be given preference to receive a COVID-19 vaccine over others. The development of clinical guidelines that establish vaccination priority protocols could optimize vaccine allocation.
