Children who have received years of season-specific flu vaccines, develop antibodies that also provide broader protection against new strains, according to a new study led by researchers at McMaster University. These anti-bodies also provide protection against strains capable of causing pandemics. The same ability, however, does not exist in adults.The findings were reported in the journal 'Cell Reports Medicine'.These findings could inform the design of a universal influenza virus vaccine for children, who are especially vulnerable to serious complications from flu, such as pneumonia, dehydration, and, in rare cases, death."Little is known about how seasonal flu vaccination impacts the immune responses in children, who are a major source of flu transmission and a very high-risk group," explained Matthew Miller, lead author of the study and Associate Professor at the Michael G. DeGroote Institute for Infectious Diseases Research. "Understanding how seasonal vaccination and different vaccine formulations shape childhood immunity is critical for effective prevention."Children and adults are fundamentally different in their immune responses to the influenza virus, explained Miller, whose lab is part of McMaster's Global Nexus for Pandemics and Biological Threats. Unlike small children, most adults have been infected with and vaccinated against flu many times throughout their lives."When we give adults vaccines, they make a very specific immune response against seasonal strains," said Miller. "Adults simply don't generate immune responses to seasonal flu vaccines capable of protecting them from pandemic viruses like children can."The researchers spent three years studying immune responses in children between the ages of 6 months and 17 years. They found that as the children grew older, they became less capable of producing broadly protective antibodies, because of their repeated exposure to influenza, through infection or vaccination.While COVID-19 related measures such as distancing and masking have resulted in lower rates of influenza, Miller warned that the flu will return, possibly in dangerous forms.Influenza has caused five pandemics in the last 100 years. The Spanish Flu of 1918-19 killed roughly 50 million people worldwide at a time when the global population was about 1.8 billion -- less than a quarter of what it is today.For the study, researchers also compared two forms of vaccine: the conventional flu shot and a nasal spray vaccine that works in the upper respiratory tract, where the infection first takes hold.Both worked equally well at generating broadly protective antibodies, which is welcome news for parents seeking a painless alternative to needles."This is an important finding because it means we have flexibility in terms of the type of vaccines we can use to make a universal vaccine for children. We now know that children's immune systems are much more flexible than adults when it comes to being able to teach them how to make these broadly protective responses," said Miller.( With inputs from ANI )Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
