SARS-Coronavirus-2 (SARS-CoV-2) and COVID-19

Most coronaviruses, including those causing the common cold, are not associated with significant mortality. The novel SARS-Coronavirus-2 (SARS-CoV-2) identified in 2019 causes a collection of symptoms that can cause severe illness, which has become known as COVID-19. The SARS-CoV-2 virus is contagious1 and infected persons can be asymptomatic2 or exhibit symptoms ranging from mild to severe. Symptoms include fever; chills; cough; shortness of breath/difficulty breathing; fatigue; muscle, joint or body aches; rash; headache; new loss of taste or smell; sore throat; congestion or runny nose; nausea or vomiting and diarrhea.3  

Complications of SARS-CoV-2 include pneumonia, acute respiratory failure, Acute, Respiratory Distress Syndrome (ARDS), acute kidney, liver, and heart injury, septic shock, disseminated intravascular coagulation (DIC), rhabdomyolysis (muscle breakdown), chronic fatigue syndrome, blood clots and death. Many complications may be caused by a condition known as a cytokine storm.4 Click to learn more about SARS-CoV-2 virus…

COVID-19 Vaccine

New ways to make vaccines including new technologies and production platforms, such as mRNA vaccines, have  become favored over the older traditional ways to make vaccines in the COVID-19 vaccine race.5 6 More than 200 different types of COVID-19 vaccines are being developed worldwide.7 Currently, three experimental COVID-19 vaccines have been granted an Emergency Use Authorization (EUA) by the U.S. Food and Drug Administration (FDA) for distribution and use in the U.S.8 9 10 Several more experimental COVID-19 vaccines are expected to be given EUA status in 2021.11 12

U.S. Emergency Use Authorization does not mean that the FDA has evaluated all safety and efficacy data and officially approved licensure of the vaccine. Instead, the EUA status allows vaccine manufacturers to release an experimental vaccine for voluntary use and requires that vaccine recipients must “have the option to accept or refuse the vaccine.”13 NVIC encourages consumers to make informed vaccination decisions and to read the FDA fact sheet and other information and resources provided on our website.

Quick Facts

SARS-CoV-2 & COVID-19

  • A few coronavirus strains can cause very severe respiratory disease with significant mortality, such as Severe Acute Respiratory Syndrome (SARS) that emerged in China in 2002-200314 and Middle Eastern Respiratory Syndrome (MERS) that was first reported in Saudi Arabia in 2012.15 SARS-CoV-2, which was identified in China in late 201916 and declared a global pandemic by the World Health Organization (WHO) in March 2020,17 18 has a much lower mortality rate than SARS or MERS.19
  • According to the U.S. Centers for Disease Control and Prevention (CDC), in 2020 about 94 percent of COVID-19 related-deaths occurred in persons over age 65 and individuals with underlying poor health conditions.20 Among those the CDC consider to be at highest risk for severe COVID-19 disease are the immunocompromised and women who are pregnant, as well as individuals with chronic heart, lung or kidney disease; obesity, type 2 diabetes, cancer, Down’s syndrome, and sickle cell disease. There are other chronic health conditions that might increase risks for severe COVID-19 disease, including asthma, high blood pressure, neurologic conditions, liver disease, cystic fibrosis, and type 1 diabetes.21

COVID-19 Vaccine

  • In December 2020, two experimental mRNA COVID-19 vaccines developed and produced by Pfizer with BioNTech and Moderna with NIAID were granted an Emergency Use Authorization (EUA) by the U.S. Food and Drug Administration (FDA) for distribution and use in the U.S.22 23 In February 2021, Janssen Biotech, Inc. of Johnson & Johnson, was granted an EUA by the FDA for an experimental COVID-19 vaccine, which uses a human advenovirus vector.24 25 26
  • As of February 28, 2021, health officials at the World Health Organization (WHO) and U.S National Institutes of Health (NIH) have warned that, while there is evidence that two doses of the Pfizer-BioNTech and Moderna vaccines can prevent symptomatic COVID-19 disease, there is a lack of evidence that the vaccines are effective in preventing infection and transmission of SARS-Cov-2.27 28 29 The Janssen/Johnson & Johnson vaccine was also granted an EUA based on efficacy data that demonstrated evidence for protection against symptomatic COVID-19 disease rather than protection against infection and transmission of the new coronavirus.30
