What is Coronavirus?Coronaviruses are a group of viruses that cause diseases in mammals and birds. In humans, coronaviruses cause respiratory tract infections that are typically mild, such as the common cold, though rarer forms such as SARS, MERS, and COVID-19 can be lethal. Symptoms vary in other species: in chickens, they cause an upper respiratory tract disease, while in cows and pigs they cause diarrhea. There are yet to be vaccines or antiviral drugs to prevent or treat human coronavirus infections.

What is Vaccine?A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as a threat, destroy it, and to further recognize and destroy any of the microorganisms associated with that agent that it may encounter in the future. The administration of vaccines is called vaccination. Vaccination is the most effective method of preventing infectious diseases; widespread immunity due to vaccination is largely responsible for the worldwide eradication of smallpox and the restriction of diseases such as polio, measles, and tetanus from much of the world.
What is Sin?In Abrahamic contexts, sin is the act of violating God's will. Sin can also be viewed as anything that violates the ideal relationship between an individual and God; or as any diversion from the ideal order for human living. To sin has been defined as "to miss the mark".
Sins fall in a spectrum from minor errors to deadly misdeeds. Catholicism regards the least corrupt sins as venial sins which are part of human living and carry immediate consequences on earth, and, if unrepented for, more painful purgation, assuming the person is destined to heaven, as it is written in the formation letter "Purgatory", "most of the early Fathers of the Church speak of a cleansing fire, though we cannot tell whether this means actual or spiritual fire."
Conversely, sins of great evil are mortal sins which bring the consequence of hell if they are not addressed either through an act of perfect contrition or going to confession about them.
