What is vaccine? Is there any vaccine for COVID-19?
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.
Vaccination is the most effective method of preventing infectious diseases such as polio, measles, and tetanus.
Is there a vaccine, drug, or treatment for COVID-19?
“There are no vaccines and medicines to prevent and treat COVID-19 up to now but several ongoing clinical trials.” WHO says
