What is a trivalent flu vaccine? Traditional flu vaccines offer protection against three different flu viruses that are expected to circulate throughout flu season. These strains include one type B and two type A strains. Trivalent flu vaccines are the traditional flu vaccines administered in prior flu seasons. Traditional trivalent flu shots are available for people 6 months and older. These inactivated flu vaccines do not contain any live influenza viruses and are given by injection. Many manufacturers are phasing out the traditional trivalent flu vaccine in favor of quadrivalent influenza vaccine, which protects against four strains of the virus. While there is no set timetable, it is possible trivalent flu shots will not be available within the coming years. What is a quadrivalent flu vaccine? Quadrivalent flu vaccines protect against four strains of influenza viruses. The quadrivalent vaccine now targets a fourth strain, which is a second type B strain, in addition to the other three strains. Scientists classify and research the most common influenza strains that cause infection to decide which strains to use in the annual vaccine. The B strains tend to circulate to varying degrees every year; however, it is difficult to know which strain will cause the most illnesses in any given year. Therefore, the quadrivalent vaccine will cover both B stains as well as the both A strains, offering additional protection. Which flu vaccine option is right for me?
