Reflection question: Immunization programs are highly effective and are a critical component of the OHS program. Do you think immunizations should be mandatory for health care workers? Discuss why or why not with evidence to support your position.

Immunization programs are a key part of Occupational Health and Safety (OHS) because they protect both healthcare workers (HCWs) and the patients they care for. In my view, immunizations should be mandatory for HCWs, with exceptions for valid medical reasons, because they reduce the spread of infectious diseases and improve patient safety.
HCWs are at higher risk of exposure to infections like influenza and can unknowingly transmit them to vulnerable patients. This creates an ethical responsibility to minimize harm. Evidence from Gualano et al. (2021) shows that vaccination rates among HCWs are often low when policies are voluntary, but mandatory programs significantly increase uptake. Higher vaccination coverage has been associated with reduced illness and better patient outcomes.
Influenza is a highly contagious respiratory infection that presents with symptoms such as fever, cough, sore throat, runny nose, and muscle or joint aches. The severity can vary from mild illness to serious complications that may lead to death. Seasonal vaccination remains the most effective method of prevention. The World Health Organization (WHO) recommends annual influenza vaccination for high-risk groups, including pregnant women at any stage, children aged 6 months to 5 years, adults over 65 years, individuals with chronic health conditions, and healthcare workers (Gualano et al., 2021).
The study also found that about 61% of HCWs support mandatory influenza vaccination, suggesting moderate acceptance of such policies. Although some oppose it due to personal autonomy but in healthcare settings, patient safety must take priority because mandatory immunization is an effective and justified strategy to protect both HCWs and patients.

Hi Ochuko, I appreciate you adding in references to add to the validity of your well-written post! The evidence is strong indicating that mandatory vaccine programs do result in higher vaccination rates which to help to keep our most vulnerable safer. I think it is important that this is something future and early nursing students are taught, that this will be an expectation of the profession, and to ensure the understanding is there as to why vaccinations are so important.

Healthcare workers aren’t just making personal health choices; they’re working with vulnerable people—elderly residents, immunocompromised patients, newborns—who can face serious harm from infections that might be mild for others. Vaccines like influenza, COVID-19, hepatitis B, and measles aren’t just about self-protection; they reduce the risk of transmitting disease within care settings. From a patient safety standpoint, mandatory programs can be justified. I do acknowlegde medical expemptions (e.g. allergies, contraindications) in which some health care workers can’t be vaccinated . According to World Health Organization( WHO) health workers as a group are at greater risk of exposure to some communicable diseases than the general population because of their contact with patients or infective material in their working environment. There is also a risk that infected health workers could contribute to nosocomial transmission of disease to vulnerable patients at higher risk for severe illness, complications and death. Protection of health workers through vaccination is therefore an important part of patient safety and infection prevention and control programmes in health-care settings, as well as a cornerstone of occupational health and safety. (WHO,2026).

Hi Maame,

You are absolutely right; immunizations protect those who are vulnerable, like older adult patients, who can have serious negative health complications from infections if acquired. As a health care worker, it’s important to stay up to date with my immunizations to reduce the risk of infecting myself and exposing vulnerable people I contact daily to harmful microorganisms. Thanks for sharing ~Melissa

According to Public Health Ontario, immunization is one of the greatest public health achievements of the twentieth century and a fundamental part of Ontario’s health care system. Public Health Ontario indicates that immunizations not only save lives but also reduce the transmission of diseases, which in turn decreases the cost of health care services (Public Health Ontario, 2026). For this reason, I believe all health care workers should be immunized because they have the responsibility to protect the patients or residents they care for. Furthermore, when health care workers are immunized, they do their part in preventing the spread of infection, which decreases outbreaks and interrupts the chain of transmission. All these factors contribute to a healthier workplace and environment and help keep the public safe.
