Flu Shots for Older Adults During Winters

Flu Shots for Older Adults During Winters. What to Know and What To Do?

The flu is an infectious respiratory ailment that can manifest itself in several ways. It’s riskier now that the COVID-19 pandemic is still a concern.

Flu can attack at any time of year, although outbreaks are most common in the fall and winter. The flu can be recovered in 1 to 2 weeks without causing severe consequences in some persons.

The flu, especially in older persons (aged 65 and up), can have life-threatening consequences. This is why older folks must get a flu shot every year.

Compared to young, healthy adults, people 65 and older are at a more considerable risk of experiencing severe flu complications. This higher risk is partly due to changes in immunological defenses as people get older.

While flu seasons vary in severity, in most cases, those 65 and older are the ones who suffer the most from severe flu illness. In recent years, it’s been estimated that between 70 percent and 85 percent of seasonal flu-related deaths and 50 percent to 70 percent of seasonal flu-related hospitalizations have occurred in those 65 and older.

What are Flu shots? 

According to a study, a flu vaccine/shot protects against the flu viruses that are expected to be the most frequent this season. Flu vaccines for 2021-2022 have been modified from last season’s vaccine to better match circulating viruses. Vaccine immunity takes roughly two weeks to develop fully.

The flu vaccine works by causing your body to produce antibodies that can protect you from the flu virus. Antigens are the substances that cause these antibodies to be built.

A high-dose vaccine is designed to boost an older person’s immune system response, minimizing their chance of infection.

Why are Flu shots necessary in the winter season? 

Simonsen et al. published an ecological analysis in 2005 that found that, despite significant gains in vaccination coverage (VC) in the elderly from about 15% in 1980 to 65 percent by 2001, winter excess morbidity and mortality rates had not decreased over this time.

If the influenza vaccine’s anticipated 50% mortality reduction is accurate, the observed excess mortality rate should have reduced as VC increased. Due to this reason, it is highly advised to get older adults to agree on having flu shots in the winter season.

What to know about Flu shots?

Vaccines against influenza are a safe and effective approach to keeping people healthy, preventing disease, and potentially saving lives. As people get older, they may be more susceptible to influenza complications. 

As a result, seniors aged 65 and up should have an inactivated influenza vaccination or a flu injection every year.

Inactivated influenza vaccination is entirely safe. It contains influenza viruses that have been destroyed and are unable to cause illness. Redness, pain, or swelling where the vaccine was given are common vaccine reactions.

Some people, especially those getting the vaccination for the first time, may experience mild symptoms after being inoculated. But it’s nothing to worry about because those mild symptoms will only stay for 2 to 3 days.

What to Do?

Before the start of the influenza season, seniors should acquire the influenza vaccine.

You should aim to obtain the vaccine as soon as possible for optimum protection, but if you can’t get it soon enough, make sure you have your dose before winter sets in.

This allows your body ample time to establish immunity (approximately two weeks) before the influenza season begins. This immunity lasts typically until the conclusion of the influenza season, which is usually in April.

Seniors should be inoculated against pneumococcal illness in addition to the influenza vaccine. The pneumococcal vaccine prevents infections of the brain, circulation, lungs, and ears.

Who should not get a flu shot?

People who:

  • After receiving an influenza vaccine within eight weeks without another reason being discovered, have had significant oculorespiratory syndrome (red eyes and cough or sore throat or hoarseness).
  • They are being treated for cancer with a checkpoint inhibitor. This could alter when you obtain your immunization.
  • Have had a life-threatening reaction to any part of the influenza vaccination or a previous dosage of the vaccine. The influenza vaccine can be safely administered to those who are allergic to eggs.


Influenza weakens the body’s defenses against other illnesses. The most common flu complication is bacterial pneumonia, which is a lung infection that affects the elderly.

People with heart, lung, or other health problems may experience increased consequences as a result of influenza. These problems can be lethal in some cases.

That is why you must consider whether your elders have had their immunizations and how their overall health is progressing.


How does the flu shot works?

The flu vaccine works by causing your body to produce antibodies that can protect you from the flu virus. Antigens are the substances that cause these antibodies to be built.
