Abbott Launched NewFour-Strain Flu Vaccine for Protection against Influenza

News Desk, News Nation 360 : Abbott, the global healthcare company, recently launched a new inactivated quadrivalent vaccine for influenza, the first of its kind sub-unit vaccine offering protection against four virus strains, in India. It is the only 0.5 ml quadrivalent flu vaccine in India that has been approved for use in children below 3 years. In fact, it can be given to children from 6 months onwards, and to adults. A 0.5 ml vaccine could improve the immune response in children below 3 years. As per a recently published study on this vaccine globally, in children, quadrivalent vaccines demonstrated superior immunogenicity or immune response compared with the alternate-lineage B-strains in trivalent vaccines, with comparable safety. A globally approved product, Abbott’s vaccine offers wide protection by immunizing against four different flu virus strains simultaneously. Hence, it is called a quadrivalent or tetravalent vaccine. It includes a second B-strain of influenza virus, compared to one B-strain included in trivalent vaccines. Recommending a vaccine can be complex for the health authorities. Dr Agam Vora, a leading Pulmonologist from Mumbai and President, Geriatric Society of India said that the National Center of Disease Control estimates show that influenza reported cases have increased 5-fold in India from 5,044 in 2012 to 28798 in 2019. and in West Bengal, influenza reported cases have increased 18% per annum from 544 in 2015 to 1,073 reported cases in 2019. A respiratory infection that affects all ages, influenza is distinct from the common cold. An influenza infection typically results in high fever lasting for 3 to 4 days, including symptoms such as headache, myalgia or muscle pain, exhaustion and severe chest discomfort and cough. Moreover, influenza can cause serious complications in certain groups such as those with respiratory ailments, cardiac disease and diabetes, as well as young children and the elderly. Influenza A and B, the two viruses that cause human disease, are currently circulating globally and in India causing seasonal outbreaks. The disease burden of influenza is substantial, and B viruses have been estimated to be associated with 25% of all influenza-related mortality.
