Prevention of influenza
Government agencies and health experts throughout the world say that the single best way to protect oneself from catching flu is to get vaccinated every year. Specially in countries where flu occurs every year. There are two types of vaccinations, the flu shot and the nasal-spray flu vaccine. The flu shot is given with a needle, usually in the arm – it has been approved for anyone older than 6 months, including healthy people and even those who have chronic medical conditions. Whereas, The nasal-spray flu vaccine is a vaccine made with live, weakened flu viruses that do not cause illness.
A flu vaccine will contain three influenza viruses – One A (H3N2) virus, one A (H1N2) virus, and one B virus. As viruses change and adapt, so do those contained within the vaccinations – the ingredients in them are based on international surveillance and scientists’ calculations about which virus types and strains may circulate in a given year. Thus, Protection begins about 2 weeks after receiving the vaccination.
The annual flu vaccinations start in September or as soon as the vaccine is on hand and should continue throughout the flu season, into January, and beyond. It is because the duration and timing of influenza seasons are never the same. Influenza outbreaks usually at peak around January, but they can happen as early as September.
For an infant whose mother was given a flu jab while pregnant is 50% less likely to be infected flu than other infants whose mothers were not given the shot while they were pregnant, according to researchers from Wake Forest Baptist Medical Center.
The influenza vaccine is not suitable for some people
Some individuals must check with their doctor before deciding to have the flu vaccine:
- Individuals who have a severe allergy to chicken eggs, chicken etc.
- Individuals with a severe reaction to a flu vaccination in the past
- People with Guillain-Barré Syndrome within 6 weeks of receiving a flu vaccine
- Infants under 6 months old
