Dear Friends.. Here find an update on INFLUENZA VACCINATION… Influenza is a serious disease that can lead to hospitalization and sometimes even death. Even healthy people can get very sick from the flu and spread it to others. An annual seasonal flu vaccine is the best way to reduce the incidence of influenza. HOW DO FLU VACCINES WORK ?... Flu vaccines provide protection about two weeks after vaccination. There are two types of seasonal flu vaccines, those using killed virus and nasal spray vaccines that contain live attenuated virus. Traditional flu vaccines (called "trivalent" vaccines) are made to protect against three flu viruses; an influenza A (H1N1) virus, an influenza A (H3N2) virus, and an influenza B virus. Each year, composition of the influenza viruses change, making the vaccine used in previous years ineffective. Each year, a new vaccine must be prepared that will be effective against the types of influenza virus that are expected to circulate in the upcoming flu season.These are known as seasonal flu vaccines. The reason being.. that the virus can mutate rapidly, leading to new subtypes of the virus. Typically, the viruses that are used to prepare flu vaccine are grown in eggs, but a newer, egg-free version of the vaccine has been developed. This is particularly important for people with an egg allergy.(Not available in India) Additionally, a special high-dose vaccine has been developed for people 65 years of age and older to elicit a stronger immune response (not available in India) WHO SHOULD RECEIVE THE FLU VACCINE ? Any Individual over 6 months of age may be vaccinated. Particularly important for… people who are at high risk of developing serious complications of flu… (1)asthma, (2)diabetes, (3)chronic lung disease (4) pregnant women   (5) over 65 years of age (6) medical personnels etc. SIDE EFFECTS… These are uncommon. but includes.. soreness at the site of the injection, muscle aching, fever, and feeling unwell. Very rarely, serious allergic reactions have been reported. One in 1 million vaccinated people may be at risk of Guillain barre syndrome. EFFECTIVENESS OF VACCINATION…. The vaccine prevents influenza illness in approximately 70%-90% of healthy adults under 65 years of age The effectiveness of the vaccine in preventing respiratory illness in people over 65 years of age is somewhat lower. The vaccine can be 50%-60% effective in preventing influenza-related hospitalization or pneumonia and 80% effective in preventing influenza-related death. The latest seasonal Flu Vaccine 2016/17 will be in the Indian market from middle of August this year.. I hope this UPDATE will be HELPFUL to most of you Thanks Dr K N Poddar


thanks for this useful post Dr Poddar the other issue is when do we get this vaccine ?? The complex pattern of influenza circulation poses challenges for timing for influenza vaccination. The National Institute of Virology analysis, using data from 2009 to 2013, showed that cities with temperate seasonality benefitted the most from vaccination in September-October, while cities with flu peaks in the July-September monsoon season, saw the most gains from vaccination in April-May. Thus, Srinagar should consider vaccination in November-December, Chennai and Vellore in October-November, and most of the rest of the country in April-May as per Indian data
