Senior citizens must get high-dose flu shots;

The high-dose flu vaccine has proven to be far more effective in keeping the elderly healthy, a study by the Oregon Health Authority said. The state public health institute collects data on flu hospitalizations every year. Researchers there tracked more than 144,000 Portland residents aged 65 years and over during last year's flu season.

They found that older people who received high-dose flu shots were 30 percent less likely to be hospitalized. High-dose injections are four times stronger than standard, because they contain more antigens that trigger an immune response to the virus. Parents often have a weaker immune system and can be susceptible to flu even with standard vaccines.

Steve Robison, lead author of the study and epidemiologist in the Oregon Immunization Program, said seniors must get the most appropriate flu vaccine to increase their immune response. High-dose vaccines are the best choice.

This study does not take into account adjuvanted vaccines – which contain extra chemicals to create a stronger reaction to the antigen. Robison said it was a better choice than the standard flu vaccine. The study focused on people who received the flu attack before December 11, 2016. The flu outbreak became the worst in mid-January, so that this period allows vaccinated people to develop antibodies to fight the virus.

Oregon is one of several countries that tracks flu hospitalization, which allows research. This research takes place during a bad flu season. All age groups tracked by the federal government have a large number of people who visit clinics and emergency departments and are hospitalized. The length of time and geographic distribution of these reports is very high.

Children die at the highest number ever. From autumn 2017 to spring 2018, 180 children die of flu – the highest in the US. About 80 percent of children who die do not receive the flu vaccine. For those who receive the vaccine, it helps reduce the need for medical attention by up to 40 percent.

The flu vaccine is covered by insurance and Medicare.

Pharmacy vaccination programs tend to charge around $ 30 for trivalent standards, and other types are slightly more expensive.
