“‘Trivalent’ flu vaccines are formulated to protect against three flu viruses, and ‘quadrivalent’ flu vaccines protect against four flu viruses. Flu vaccines do NOT protect against infection and illness caused by other viruses that can also cause flu-like symptoms.” (Centers for Disease Control and Prevention) There are about 29 different known strains of the influenza virus, 18 hemagglutinin subtypes and 11 neuraminidase subtypes: “Hemagglutinin and neuraminidase protrude from the outer surface of the influenza virus and neuraminidase is a constituent of the enveloping membrane that surrounds the viral contents.”(Encyclopedia) This goes to show that when given the flu vaccine, you are not guaranteed to be protected for the specific strain you were infected with. Studies have shown that the vaccination tends to work more effectively when you receive the vaccine for the first time, compared to getting it multiples times. It is as if the influenza virus can become immune to the people that have received multiple doses of the vaccine within their life, decreasing the effectiveness. The flu virus is an example of where vaccines could be seen as unnecessary, because the vaccination that is labeled to prevent influenza, does not truly prevent it as a whole disease, but only certain strains of …show more content…

In my opinion, it is worse to have the potential of getting infected than to just be protected in case people around you get infected. Personally, my family believes in vaccines, so we are always up-to-date on the suggested vaccination schedule that the doctor provides. It is better to have taken preventive measures against diseases, than to not get vaccinated and have no protection against the disease. As discussed above, vaccinations are safe and effective, because they must be critically analyzed and thoroughly tested by professional doctors and scientists, to approve or deny the allowance of certain vaccine uses. Vaccines are required for school enrollment due to the fact, that at school there are hundreds of kids, if not thousands, so diseases and illnesses can easily be spread among people. Lice is an excellent example of how things can spread so quickly, especially among children. If a child shows up to school with lice, then the kids that they play with or are in the same class as the lice-infested child, they have a high chance of coming home
