Influenza, better known as the flu, is a highly contagious virus that attacks the respiratory system. The virus is passed from person to person though respiratory droplets emitted when an infected person talks, sneezes, or coughs. People find themselves at risk for contracting the flu when inhaling the infected droplets or touching their eyes, mouth or nose after touching something that has been infected.
DTaP is a vaccine given to infants and young children and is administered in 5 separate shots. Licensed in 2005, the CDC estimates that these vaccines will prevent 732,000 deaths of children born between 1994 and 2013. The vaccination protects against Diphtheria, Tetanus, and Pertussis.
Research and case studies suggest that SIRVA is caused by improper administration of the vaccine, rather than the vaccine components. It is recommended that injections be administered into the deltoid muscle in the upper arm for adults. However, even trained medical professionals can misjudge the placement of an injection, placing it too high or too deep, outside of the recommended injection site.
