Who Should Get the Annual Flu Shot, and How Effective Is It?
The Annual Flu Shot is recommended for nearly everyone Aged six months and older, especially those who are at higher risk for complications from the flu. This includes young children, older adults, pregnant women, and people with chronic health conditions such as asthma, diabetes, or heart disease. These individuals are more vulnerable to serious health complications from the flu, such as pneumonia or hospitalization. Health professionals, caregivers, and those who are in close contact with vulnerable populations should also get the vaccine to help prevent spreading the flu. For most people, the flu shot is safe and beneficial, providing protection against the seasonal flu virus.
The effectiveness of the Flu Shot can vary from year to year, depending on how well the Vaccine matches the circulating virus strains. On average, the flu vaccine reduces the risk of illness by 40% to 60% when there is a good match between the vaccine and circulating flu strains. While it’s not perfect, the flu shot still significantly lowers the likelihood of severe flu-related outcomes, such as hospitalization or death. Even if the flu shot doesn’t prevent illness entirely, it can make symptoms less severe and shorten the duration of the illness. Annual vaccination remains the most effective way to reduce the burden of flu on both individuals and communities.
