Vaccines are a topic of discussion right from the birth of an individual as they are vital in healthcare. Since the outbreak of the coronavirus, lots of different vaccines have hit the market. Nevertheless, some individuals opt not to utilise them, primarily due to a greater concern about the potential side effects rather than the positive benefits. This article discusses the importance of vaccines.
Vaccines are a type of active immunity that strengthens our immune system and help our body develop resistance to some viruses, preventing us from contracting dangerous diseases before we even come into contact with them. They train our immune system to produce antibodies in the same way that it does in the event of an actual illness exposure. Vaccines include only destroyed or weakened versions of pathogens like viruses or bacteria, therefore, they do not cause the disease or put the individual in danger of its complications.
Vaccines have played a huge role in eradicating deadly diseases like smallpox and controlling others such as polio, measles, and whooping cough. Their impact extends to both individual and community protection. Before widespread vaccine use, surviving childhood without diseases like measles, mumps, rubella, chickenpox, and whooping cough, was rare. Individuals with weakened immune systems, undergoing chemotherapy, or refusing vaccination rely on herd immunity for protection. Herd immunity occurs when a large part of the population is immune through vaccination or prior infection, reducing disease transmission. Relying on prior infection alone is unrealistic and dangerous. Vaccines are crucial for establishing herd immunity, significantly reducing the prevalence of diseases like polio and chickenpox. Their role in maintaining herd immunity emphasises their vital contribution to public health.
Vaccines are safe and effective, backed by numerous studies and thorough clinical trials done prior to releasing the vaccines to the public. Side effects (if any) are mostly temporary and mild and are far outweighed by the much greater risk of the diseases they prevent. So, before deciding not to receive a vaccination, it is important for an individual to learn its importance.
