Does the flu vaccine change by season? Is a pastor given a specific chapter?
Arabs Weather medical site - flu is a contagious respiratory disease caused by influenza viruses. If untreated, influenza infection can lead to hospitalization or death, especially in the elderly, children, and people with certain health conditions such as low immunity, chronic diseases, or otherwise.
There are two main types of influenza viruses : type A and type B, which are responsible for seasonal influenza epidemics.
The best way to prevent the flu is to get vaccinated with the flu vaccine (Influenza Vaccine) during its spread every year.
The impact of weather on influenza
Many people associate cold weather with flu. While the weather is not directly responsible for people getting sick, viruses that cause colds and flu can spread more easily at low temperatures, and exposure to cold and dry air adversely affects the body's immune system.
The impact of cold weather on viruses
One study published in Environmental Health in 2014 examined whether differences in temperature and humidity led to a higher risk of influenza, and the researchers found that a 3-day decrease in temperature and humidity increased the risk of flu infection in participants. In the same study, the researchers found that the majority of injuries occurred at temperatures below zero.
Influenza viruses live and spread more easily in cold and dry air, according to a study published in the Journal of Virology in 2014 and conducted on guinea pigs that the ideal temperature of the influenza virus is 5 degrees Celsius.
The effect of cold weather on the immune system
Many researchers believe that exposure to cold weather can negatively affect a person's immune response, making it harder for the body to fight germs. A 2015 study found that exposing cells taken from mice to low temperatures reduced the immune response to cells against viruses. . This may be because:
- Low levels of vitamin D during the winter months In many people due to low sun exposure, many researchers believe that vitamin D plays a key role in maintaining the immune system.
- Spending more time indoors, as people tend to spend more time indoors during the winter months, it is known that the spread of viruses and infections is large the more people gathered in one place.
- Vasoconstriction, breathing in cold and dry air leads to narrowing of the blood vessels in the upper respiratory tract to maintain heat inside them. This may prevent white blood cells from reaching the mucosa, making it difficult for the body to resist germs.
Why should flu vaccination?
Flu is a serious disease that can lead to hospitalization and sometimes death. Millions of people get the flu every year. Hundreds of thousands of them are hospitalized, and thousands may die of flu-related causes each year.
The annual seasonal flu vaccine is the best way to help protect against flu. Vaccination has been shown to have many benefits including reducing the risk of influenza, hospitalization, and even the risk of death associated with influenza in children.
Why should be vaccinated with flu vaccine every year?
The flu vaccine should be vaccinated every season for two reasons:
- The immune protection of a person from vaccination decreases over time, so an annual vaccine is required for optimal protection.
- The influenza virus is constantly changing its shape, so flu vaccines are updated from season to season, and the vaccine is made to protect against viruses that research suggests may be the most common during the next flu season.
When should I get the vaccination?
A person should get the flu vaccine before the flu viruses begin to spread.It takes about two weeks for the vaccine to start working, so vaccination should be done early in the fall, before the flu season begins.
The CDC recommends that people get the flu vaccine by the end of October, if possible. However, later vaccination is still beneficial and vaccination should continue to be provided as long as influenza viruses are spread. An expired vaccine is available.
No one can predict when flu will occur in a particular season, but the CDC indicates that 75% of influenza seasons peak in January or February.
Early vaccination (i.e. in July and August) can lead to decreased immunity protection at the end of the flu season, especially in the elderly.
Children who need two doses of vaccine should start vaccination early, because the time difference between the two doses should be at least four weeks.
Protection from influenza vaccine is believed to last for at least 6 months, and protection decreases over time.
Weather changes and their impact on the ear
At what time of day would you prefer to give the vaccine?
A 2016 study in the journal Vaccine peer-reviewed showed that people who were vaccinated in the morning had a better response to the vaccine, meaning that they had high levels of antibodies to influenza after a month of vaccination, which in turn leads to lower rates of influenza, so it is preferred Give vaccination before 11 am.
What side effects can occur after getting a flu vaccine?
While a flu vaccine cannot infect a person with influenza, some mild and short-term side effects are possible.These effects include:
- Pain, redness, or swelling at the injection site.
- Headache (low score).
- High temperature.
- Muscle pain.
- nausea.
- fatigue.
