Co-Administration of H1N1 Influenza and seasonal Influenza Vaccine

There are still debates weither the H1N1 Influenza and seasonal Influenza Vaccine should be considered into one injectable version, since both vaccines have been well tolerated containing inactivated influenza viruses. Studies have shown that co-administration of the two vaccines does not impair or interact with the immune response to either one. According to an article from the National Institute of Allergy and Infectious Diseases (NIAID), there was a clinical trial on approximately 400 healthy volunteered people aged 18 to 64 years and 400 healthy volunteered people 65 years of age and older who received 2009 H1N1 influenza vaccine at the same time as seasonal influenza vaccine. As a result, among 25 volunteers aged 18 through 64 years, 76 percent showed a robust immune response to the 2009 H1N1 influenza vaccine. Also, among 25 volunteers aged 65 years or older, 80 percent developed a robust immune response to the 2009 H1N1 influenza vaccine. Overall, combining the vaccine wouldn’t be a bad idea for healthy adults, but we still have to take in consideration that the trial only tested healthy adults. The majority of people now in days usually have at least one health problem. What about for children? Would combining this vaccine be too much for a child’s immune sys. to handle, or can it cause an impair immune response in children? It wouldn’t be a bad idea to first over look any outcome before combining the vaccine.
