A Review of the Impact of the COVID-19 Pandemic on Health Workers’ Sentiment towards Influenza Vaccination

During the COVID-19 pandemic, immunization of health workers (HWs) has become a top priority. According to the Centers for Disease Control and Prevention (CDC), reducing the risk of patients catching influenza from health professionals, protecting healthcare staff and their families against influenza, and reducing health professionals’ absenteeism and consequently costs on the National Health Service are key reasons for the cost-effectiveness of influenza vaccination strategies among HWs. Although healthcare professionals are cognizant of the significance of immunization for protection against infectious diseases, there are various obstacles and factors that impede the uptake of influenza vaccines. Vaccine hesitancy among HWs is one of the major hurdles to optimum immunization practices.

In an article published by the researchers of the WFPHA and its International Immunization Policy Taskforce, they investigated the impact of the COVID-19 pandemic on the sentiment of influenza vaccination among HWs through the identification of relevant determinants, barriers, and interventions to counteract vaccine hesitancy.

Determinants of Vaccine Hesitancy

According to the article, age, gender, comorbidities, profession cadres, and vaccination history are the determinants of vaccine hesitancy among healthcare staff. Within the COVID-19 context, physicians and residents were more willing than nurses to adhere to influenza vaccination. Young HWs, particularly males and those with chronic comorbidities, demonstrated the highest acceptance of the influenza vaccine. HWs’ immunization history is associated with higher influenza vaccine adherence.

Enablers of Vaccine Acceptance

There are several factors that influence the acceptance of influenza vaccines by healthcare staff. According to the article, healthcare staff’s knowledge of the influenza vaccine, concerns about protecting themselves or others, and the rising perception of risk and fear from COVID-19 infection are among the main factors.

Barriers to Vaccine Acceptance

According to the article, the main barriers were negative perceptions about vaccine safety and effectiveness, insufficient time for vaccine uptake, and confidence in natural or acquired immunity.

Interventions for Vaccine Hesitancy

Interventions adopted during the COVID-19 pandemic to increase HWs’ influenza vaccine acceptance ranged from: awareness campaigns alongside education and training to target hesitancy; mandatory HWs’ influenza vaccination; promotion of vaccine culture in workplaces; the incentive approach; and increasing vaccine affordability and accessibility.

According to the article, the COVID-19 pandemic had a critical impact on the success of influenza campaigns among HWs. In the context of COVID-19, confidence in influenza vaccines and the perception of risk from COVID-19 infection have increased among HWs.
