COVID-19 Vaccines in the USA

As of June 18, 2021, the US Food and Drug Administration (FDA) had issued three Emergency Use Authorizations for COVID-19 vaccines. The FDA has not Approved any experimental COVID-19 vaccine.

Pfizer-BioNTech COVID-19 Vaccine - Internationally known as Comirnaty, this vaccine is a nucleoside-modified RNA formulated in lipid nanoparticles and encodes an optimized SARS-CoV-2 full-length spike protein antigen. 

Moderna COVID-19 Vaccine - The COVID-19 Vaccine Moderna (mRNA-1273) is an mRNA vaccine candidate against the novel coronavirus SARS-CoV-2 encoding prefusion stabilized form of the Spike (S) protein. In Japan, this vaccine is known as COVID-19 Vaccine Moderna Intramuscular Injection.

Janssen COVID-19 Vaccine - The Johnson & Johnson - Janssen COVID-19 single-shot experimental vaccine leverages Janssen's technologies. Janssen’s AdVac® vectors are based on a specific type of adenovirus, which has been genetically modified so that it can no longer replicate in humans and cause disease.

The U.S. CDC reported data on June 18, 2021, representing about 44.7% of the US population had been fully vaccinated with an Authorized COVID-19 vaccine.

COVID-19 vaccines effectively prevent mild symptoms, severe disease, and hospitalizations due to COVID-19 disease. But it is still possible for a fully vaccinated person to become infected if exposed to the SARS-CoV-2 beta coronavirus. In addition, because the U.S. VAERS empowers anyone to report possible side effects from vaccines, it includes reports that might or might not be caused by vaccines.

As of June 14, 2021, the VAERS had received 511 reports of myocarditis or pericarditis among people ages 30 and younger who received a COVID-19 vaccine. Most cases have been reported after mRNA COVID-19 vaccination (Pfizer-BioNTech or Moderna), particularly in males. Through follow-up, including medical record reviews, the CDC and FDA have confirmed 323 reports of myocarditis or pericarditis. 

More than 310 million COVID-19 vaccines were administered in the USA from December 2020 through June 14, 2021. During this time, VAERS received 5,343 reports of death among people who received a COVID-19 vaccine. However, a review of available clinical information, including death certificates, autopsy, and medical records, has not established a causal link to COVID-19 vaccines, says the CDC.

In Europe, the European Medicines Agency has authorized four COVID-19 vaccines. And the World Health Organization updated its COVID-19 vaccine authorization Listing on June 16, 2021. Globally, about (102) COVID-19 vaccine candidates undergoing clinical trials and 185 candidates in pre-clinical development reported GAVI on June 16, 2021.
