Senior citizens should do high-dose flu vaccine, says Oregon study | Northwest News


In a study conducted by the Oregon Health Authority, the high-dose flu vaccine has been shown to be much more effective to keep the elderly healthy.

The state health institution collects data on influenza per year. The researchers followed the residents of the Portland region for more than 144,000 during last year's flu season. They found that 30% less likely to be hospitalized for high-dose flu vaccines.

A high dose shot is four times stronger than the standard because it contains more antigens that trigger an immune response to a virus. Elderly people usually have a weak immune system and can be flu-sensitive even with a standard vaccine.

Steve Robison, lead author of the study and epidemiologist in the Oregon Immunization Program, said the elderly should get an optimal flu vaccine to boost immune responses. High-dose vaccines are the best choice.

In the study, adjuvanted vaccines containing an extra chemical to create a stronger response to antigens have not been taken into account, but Robison said they are a better option than a standard influenza vaccine.

The study focused on influenza vaccines before December 11, 2016. The influenza epidemics worsened in mid-January, so this time allowed humans to develop antibodies to fight viruses.

Oregon is one of the few states that make it possible to study and monitor the influx of influenza.

This work was particularly bad during the flu season. All age groups followed by the federal government had a large number of people visiting the outpatient and emergency departments and hospitalized for the flu. The length and geographic spread of these reports were also exceptionally high.

Children have died at the highest rate ever. From the fall of 2017 to 2018, 180 children died from the flu – the highest in the United States in 2013, increased to 171.

Approximately 80 percent of children who died had not received a flu vaccine.

It reduced the need for medical care by 40 percent for vaccines.

Influenza vaccination is covered by insurance and Medicare. Pharmacy vaccination programs tend to demand around $ 30 for a standard trivalent shot, and other species are a little more expensive.
