Flu Vaccine May Offer Limited Protection Against New strain, experts Warn
London – Health officials are urging individuals eligible for a flu vaccine to get it as soon as possible, despite warnings that this year’s formulation may not be a perfect match for a newly circulating, mutated strain of the influenza virus. Experts say this could lead to a more challenging flu season, with a focus shifting towards mitigating severe illness rather than preventing infection altogether.
this year’s vaccine was designed and approved for production in February, based on the strains circulating at that time. Though,a new viral mutant emerged in june,creating a mismatch. While the vaccine will still stimulate antibody production, offering some protection, experts anticipate a lower level of efficacy compared to years with a closer strain match. “Some protection is better than no protection, but this year is likely to be one of the years were the amount of protection is less than it is in years when the match is better, it’s not an ideal situation,” stated Professor Fraser.
Professor Lewis emphasized the importance of vaccination, calling this “absolutely the most crucial year” to get the flu shot, and specifically urging those contacted by their General Practitioner to schedule an appointment promptly. The focus, officials say, will be on lessening the severity of the illness and reducing the risk of complications.
Alongside vaccination, doctors have been reminded of the benefits of early antiviral treatment, which can significantly reduce the risk of complications from the flu.
The situation is already impacting other parts of the world. Japan is currently experiencing an early flu season and has implemented temporary school closures to help curb outbreaks – measures distinct from the widespread lockdowns seen during the COVID-19 pandemic. These closures are part of the country’s established strategy to disrupt viral spread.
While the future trajectory of the flu season remains uncertain, Professor Lewis acknowledged the possibility of a swift decline in cases, stating, “It might all go away by next week,” but added, “I don’t think it will.” Health officials continue to monitor the situation closely and advise the public to prioritize preventative measures.
