The age group should have high doses of influenza, says a study in Oregon Northwest News


A high-dose influenza vaccine has proven to be far more effective in maintaining healthy older people, according to a study by the Oregon Health Authority.

Every year, the National Public Health Agency collects data on hospitalization of influenza. Last year, the researchers followed more than 144,000 Portland residents aged 65 years or more. They found that elderly people who received a high-dose flu were 30% less likely to end up in the hospital.

The high dose is four times stronger than the standard, as it contains several antigens that trigger an immune response to the virus. Retirees often have a weaker immune system and may also be susceptible to influenza with a standard vaccine.

Steve Robison, lead author of the study and epidemiologist in the Oregon immunization program, said teenagers should receive an influenza vaccine that best adapted to strengthening their immune response. High-dose vaccines are the best bet.

The study did not take into account adjuvanted vaccines – which contain an additional chemical intended to create a stronger response to antigens – but Robison said that this is also a better option than a standard flu.

The study focused on people who received flu before December 11, 2016. Influenza outbreaks have become the worst in mid-January, and this timeframe has allowed vaccinated people to develop anti-virus antibodies.

Oregon is one of the few countries to monitor hospitalization due to influenza, which made the study possible.

This study was conducted during a particularly poor season of flu. All age groups, monitored by the federal government, had a large number of people who visited clinics and emergency departments and were hospitalized for influenza. The period and geographical distribution of these reports was also unusually high.

Children died at the highest level. From autumn 2017 to spring 2018, 180 children died of flu – the highest in the US, where in 2013, 171 children.

Approximately 80 percent of children who died died of an influenza vaccine.

For those who received the vaccine, they helped reduce the need for medical care by 40 percent.

The flu vaccine covers insurance and Medicare. Drug-stopping programs usually charge around $ 30 for a standard trivalent shot, while others are slightly more expensive.
