This article has all the information on how the COVID-19 vaccine works, what are the potential side effects and much more. Let’s begin.
How do vaccines work?
Vaccine helps in the development of immunity to a virus or other germ. A vaccine includes a less dangerous component of the germ — or something made to look or act like it. The immune system of the body produces antibodies that fight the germ and prevent a person from being infected. If the individual is exposed to the germ again, their immune system will be able to identify it and learn how to combat it.
Is there a vaccine for the coronavirus disease?
Yes, the FDA has granted an emergency use authorization (EUA) to three COVID-19 vaccines. Pfizer’s vaccine was approved on December 12, 2020; Moderna’s version was approved on December 18, 2020; and Johnson & Johnson’s vaccine was approved on February 27, 2021.
How will a vaccine prevent COVID-19?
Every viral particle that causes COVID-19 has protein spikes. These spikes assist virus attachment to cells and disease transmission. Some coronavirus vaccines are being developed to help the body recognise these spike proteins and combat the coronavirus that contains them.
When anyone receives a vaccine, their chances of getting infected are reduced if they come into contact with the virus. But more important thing is the effective vaccine is preventing serious diseases, hospitalization, and death of a person. At this time, all three vaccines are extremely effective in avoiding COVID-19-related severe illness, hospitalization, and death. Because of widespread vaccination, the coronavirus can infect fewer citizens. This will limit the virus’s ability to spread across populations while also limiting its ability to evolve into new forms.
Safety and Effectiveness of a COVID-19 Vaccine
How do we know if a vaccine is safe and effective?
A COVID-19 vaccine must pass certain tests and meet certain requirements in order to be considered safe and reliable. Scientific evidence from testing is used by organizations including the National Academy of Sciences, the National Institutes of Health, and the Food and Drug Administration (FDA) to help determine whether and when new medications and vaccines should be made available to the public. It’s important to remember that you can not get infected with COVID-19 by a vaccine itself. The vaccines contain proteins or other biological substances to activate the immune response, but they do not contain the coronavirus.
Will children receive a COVID-19 vaccine?
FDA has authorized the vaccine from Pfizer-BioNTech for distribution to people ages 16 years and older.
For children under the age of 16, no COVID-19 vaccine has been approved. At least one study is currently underway, with participants aged 12 to 18 and their parent’s permission. However, enough information on the timing, protection, efficacy, and practical aspects of vaccinating children for the coronavirus, especially children under the age of 12, may not be available until late 2021 or even 2022.
