There is a lot of misinformation circulating online about this idea of “immunity debt”, so it’s important that you get your facts right. #ScienceUpFirst [1/10]

The term “immunity debt'' was coined and first mentioned in an opinion paper published in August 2021. The author discusses the possibility of an immunity gap from the COVID-19 sanitary measure and the importance of vaccination to prevent outbreak. #ScienceUpFirst [2/10]

Misinformers are now using this idea of “immunity debt” to suggest that the COVID-19 public health measures have weakened people’s immune systems by preventing them from being exposed to pathogens. There are 2 problems with how they use this idea. #ScienceUpFirst [3/10]

#1 Your immune system was not off duty for the past 2 years. It was still exposed everyday to a multitude of microbes. #2 Our immune system does not weaken if it is not challenged for a while like muscles do. #ScienceUpFirst [4/10]

However, our immune system might have limited exposure to certain pathogens that cause seasonal illnesses and this is especially true for children. Right now, many children are struggling with RSV, a common cause of respiratory infection in infants. #ScienceUpFirst [5/10]

Pre-pandemic, children were mainly exposed to RSV throughout the fall/winter. Now that most sanitary measures are lifted, many children are being exposed to RSV: - For the 1st time. - All at once #ScienceUpFirst [6/10]

High hospitalization rates in children are potentially due to a combination of different factors. #ScienceUpFirst [7/10]

There is a shortage of over the counter pain & fever reducing medicine for children right now in Canada. Without these medications to manage the symptoms of viral infection, concerned parents turn to hospitals and clinics for help instead. #ScienceUpFirst [8/10]

COVID-19 infections have been associated with disruption in the innate and adaptive immune responses in some populations, which could increase the susceptibility for subsequent infections. #ScienceUpFirst [9/10]
