I went through the below Twitter thread on how mRNA vaccines (Pfizer and Moderna) work.

As per that, these vaccines prepare our body to fight the virus in case we get infected in the future. Does that mean these mRNA vaccines can't cure COVID, but they only make uninfected people less vulnerable to it?

    That's generally what a vaccine is. – Bryan Krause Dec 25 '20 at 19:39

    Has your research turned up any vaccine known to cure a disease? – Carey Gregory Dec 26 '20 at 17:31

    Thanks, both of you. The confusion was about the difference between vaccine and antiviral. – Bee Jan 3 at 12:20

Good evening! Vaccines do not cure. Vaccination is necessary in order for the body to get over the virus in a mild form and develop immunity to the pathogen

Thanks, Bryan and Carey for the heads up. Based on your responses, I did a bit of further research and finally understand it. The confusion was about the difference between these vaccines and antivirals. I was assuming whatever the scientists have been working on were antivirals. But I was wrong, they are not antivirals, but vaccines.
