Flu vaccine made by faster method is also effectiveFebruary 23rd, 2011 - 2:15 am ICT by Aishwarya Bhatt
London, Feb 22 (THAINDIAN NEWS) A new research published in the online journal The Lancet claims that speeding up flu vaccine development does not make the final product less effective compared to the current ones.
The research was led by P. Noel Barrett from Baxter BioScience, Biomedical Research Centre, in Orth/Donau, Austria.
The researchers claim that using a new method that involves sell culture method actually improves the strain selection process and it reduces the chance of strain circulation.
The researchers studied 7250 healthy American adults in 36 centers all over the country. The participants were all aged between 18 and 49 years. During the flu season between 2008 and 2009, the participants were randomly given either a placebo or a vaccine.
It was found that those that were given the vaccine had 78.5% protection from the flu.
The researchers after the study explained that, “Comparison with previously published meta-analyses shows that the Vero-cell-derived seasonal influenza vaccine is at least as immunogenic and efficacious as traditional egg-derived vaccines. Our data also provide the first evidence that correlates of protection established for egg-derived influenza vaccines are also appropriate for cell culture-derived vaccines.”
They conclude that vaccines created in that way are safe.
