As the COVID-19 pandemic has spread around the globe, many people have unfortunately lost their lives. Scientists and world health leaders have struggled and worked tirelessly to offer solutions and weapons against this Sarsc-CoV-2 virus. Part of the solution: the vaccines against to COVID-19 virus. Some of them are more popular in some parts of the world and vice versa, but so far, there have been several types of vaccines available produced by several companies across the globe. Some of the most known ones are Pfizer, Astra Zeneca, Johnson & Johnson, Moderna, Sinovac and Sputnik. According to statistics published on Word data, there are vaccines available; only 24.3% of the world population has received at least one vaccine dose.
Unvaccinated people stand a higher risk.
Dr. William Schaffner from the University of Vanderbilt has declared for the CNN that unvaccinated people are responsible for developing different COVID-19 variants. To put it in simpler words, just like any other virus, once it reaches hosts, the Sars-CoV-2 virus mutates inside them, and then it further spreads. Different COVID-19 variants are born due to the several mutations the virus suffers from one host to another, and each variant has its particularities. Some of the most known variants have been assigned Greek letters: The Alpha, the Beta, The Gamma and the Delta. The Delta variant, originated in India, appears to be the most dangerous one yet, because it has the highest transmissibility rate, and it can become deadly for unvaccinated people.
What can be done?
To stop the virus from further mutation and spreading, more people need to receive any of the COVID-19 vaccines available worldwide. If most of the members are vaccinated in a community, then the transmissibility will be lower, and it will be easier to take care of those who are too young or too weak to get the vaccine.
