Fall 2022 was notably marked as ‘a tsunami for viruses’, says Dr. Jonathan Pinsky, the Medical Director of Infection Control and Prevention at the Edward Hospital in Naperville. The surge in cases wasn’t only exclusive to the COVID-19 virus but also included the highest numbers of influenza and RSV (respiratory syncytial virus) cases seen in the past decade or so. As we look towards another influenza season, amidst an active COVID-19 pandemic, and burgeoning RSV cases in some states, infection prevention professionals have an important role to play.
For the first time in history, we find ourselves equipped with vaccines targeting all three of these viruses, meaning we have a chance to prevent another ‘viral tsunami’. Prompt vaccination for flu and COVID-19 is essential, but it is equally important to explore whether an RSV vaccination could be a necessary addition.
In regards to the influenza vaccine, the Centers for Disease Control (CDC) advises everyone aged 6 months and older to get vaccinated before the month ends, as the shot takes two weeks to offer full protection. The importance of flu vaccination is underscored by the grim statistics from the last season when approximately 360,000 patients were hospitalized due to the flu, and sadly, 97% of them were unvaccinated. Around 21,000 people lost their lives in the same season.
For COVID-19, the CDC recommends a newly reformulated shot for everyone aged 6 months and older. Remember, immunity wanes and the virus evolves, thus a recent shot offers better protection. As for RSV, mostly it gives adults just a common cold, but it is quite risky for babies, young children, and older adults. In fact, it is one of the main reasons for pediatric hospitalizations each year. Vaccination strategies against RSV depend on factors like age, health risks, and the advice of your healthcare provider. However, there are new vaccines specifically recommended for older adults (60 and above) and pregnant women between 32 to 36 weeks gestation when in RSV season.
Vaccinations for these viruses won’t entirely rule out the chance of illness but taking timely, appropriate vaccines will definitely diminish risk and help save lives.
