Are COVID-19 vaccines reliable?
Updated: Feb 25, 2021
In December 2019, the first Covid case was reported in Wuhan, China. Scientists soon discovered that the Coronavirus has the similar DNA of which the SARS virus has.
The symptoms of the Coronavirus are high fever, dry cough, headache, loss of taste and smell, difficulty breathing, etc. You wouldn’t know if you have covid because you could be in an incubation period. If you're still in an incubation period, you can still spread the virus to others.
Till now, there have been 112 million cases, 63.2 million people recovered, and 2.48 million deaths globally.
Many people have desperately waited for the Covid vaccine because the number of cases was rapidly increasing day by day. Finally in January 2021, Covid vaccines were released by many medical companies such as Astrazeneca, Pfizer, Moderna, and Janssen.
However, some people question if the vaccines are safe? Until today, about 175 million people got vaccinated and according to the CDC, it seems that Covid vaccines are safe, but there may be some side effects such as chills or tiredness.
Even with the vaccine, the best way to prevent getting Covid is being careful. You should wash your hands often. If you can’t wash your hands, use hand sanitizer.
