When diseases spread or epidemics strike, the first step public officials take is to administer vaccinations. A vaccination stimulates antibody production to fight the disease which further leads to immunity. When a vaccine is physically injected into an individual, the body will fight the disease with its own natural antibodies. This is known as active immunity. On the other hand, if the body receives antibodies and does not make them on its own, this is referred to as passive immunity. Overall, passive immunity does not last as long as active immunity, and soon enough the disease can return in full force.
Many people are concerned with the possible side effects of vaccinations, including hypersensitivity and neurological disorders. But after receiving a vaccination of the weakened disease, the body will create an immune response to prevent future outbreaks of it. The CDC encourages people to receive scheduled vaccinations in order to protect themselves and others from disease outbreaks. In particular, vulnerable populations, such as the elderly and young, should receive vaccinations regularly since they are most susceptible to diseases. It is best not to take the risk when facing a health threat, and to receive a vaccination whenever scheduled.
It is imperative that the community is informed about any potential disease threats that may currently be taking place. It is the job of public health officials to notify the public if preventative measures should be taken in the case of spreading diseases or other health dangers. Preparation and following the directions of officials can help protect from unwanted threats.
