COVID-19 vaccines protect people from coronavirus disease. There are four types of vaccines at present. They are categorized as viral vector, nucleic acid (RNA and DNA), whole virus, and protein subunit. Though vaccines offer significant protection against the disease, chances of breakthrough infections are increasing. These vaccines are administered intramuscularly. Pain at the injection site, fever, muscle pain, etc., are its side effects in some people. Pfizer, Moderna, Covaxin, Sputnik, AstraZeneca, Johnson and Johnson's Janssen, Sinopharm, Novavax, Sinovac, etc., are some available approved COVID-19 vaccines.
