The FDA-approved COVID-19 vaccines include those from Pfizer-BioNTech, Moderna, and Johnson & Johnson (Janssen), with specific formulations and eligibility criteria for different age groups.
The Pfizer-BioNTech COVID-19 vaccine, known as Comirnaty, was the first to receive full FDA approval in August 2021 for individuals aged 16 and older. For those aged 5 and older, the vaccine is available under EUA. This mRNA vaccine requires a primary series of two doses, followed by booster shots recommended by the Centers for Disease Control and Prevention (CDC) to maintain immunity against evolving variants. The FDA's approval was based on robust clinical trial data demonstrating high efficacy in preventing severe illness, hospitalization, and death from COVID-19.
Moderna’s COVID-19 vaccine, marketed as Spikevax, received full FDA approval in January 2022 for individuals aged 18 and older. Like Pfizer’s vaccine, it is available under EUA for individuals aged 6 months and older. This mRNA vaccine also requires a primary series of two doses, with booster recommendations aligning with CDC guidelines. The FDA’s approval was supported by extensive data showing strong protection against COVID-19, including severe outcomes, across diverse populations.
The Johnson & Johnson (Janssen) COVID-19 vaccine is unique as it is a viral vector-based vaccine and requires only a single dose for the primary series. It received full FDA approval in April 2022 for individuals aged 18 and older, with EUA covering the same age group. While initially praised for its single-dose regimen, the CDC now recommends mRNA vaccines (Pfizer or Moderna) over the Janssen vaccine due to rare but serious side effects, such as thrombosis with thrombocytopenia syndrome (TTS). However, it remains an option for individuals who cannot receive mRNA vaccines or prefer a single-dose option.
In addition to these fully approved vaccines, the FDA has authorized updated (bivalent) COVID-19 vaccines under EUA to target the original virus strain and the Omicron subvariants.

Emergency Use Authorization (EUA) vs. FDA approval
The U.S. Food and Drug Administration (FDA) plays a critical role in ensuring the safety, efficacy, and availability of vaccines. When it comes to vaccine approval, there are two primary pathways: Emergency Use Authorization (EUA) and full FDA approval. Understanding the differences between these two processes is essential, especially in the context of public health emergencies like the COVID-19 pandemic. As of recent data, the FDA has fully approved several vaccines, while others have been authorized under EUA. For instance, the Pfizer-BioNTech COVID-19 vaccine transitioned from EUA to full approval in August 2021, while others remain under EUA.
Emergency Use Authorization (EUA) is a mechanism that allows the FDA to expedite the availability of medical products, including vaccines, during public health emergencies. Under an EUA, the FDA may authorize the use of an unapproved product or an unapproved use of an approved product if certain criteria are met. These criteria include a declaration of emergency, evidence that the product may be effective, and a determination that the known and potential benefits outweigh the known and potential risks. Importantly, EUA is not the same as full approval. It is a temporary measure designed to provide access to potentially life-saving treatments when there is insufficient time to complete the full FDA approval process. For example, during the COVID-19 pandemic, multiple vaccines, such as Moderna and Johnson & Johnson, were initially authorized under EUA before some received full approval.
In contrast, full FDA approval is a rigorous and time-intensive process that requires substantial evidence of a vaccine’s safety and efficacy. Manufacturers must submit comprehensive data from clinical trials, including long-term follow-up data, to demonstrate that the vaccine works as intended and that its benefits outweigh its risks. This process typically takes several years, as it involves extensive review of manufacturing quality, clinical trial results, and post-marketing surveillance. Full approval provides a higher level of assurance to the public and healthcare providers about the vaccine’s safety and effectiveness. As of recent updates, vaccines like Pfizer-BioNTech and Moderna have received full FDA approval for certain age groups, while others remain under EUA or are pending further review.
The key difference between EUA and full FDA approval lies in the level of evidence required and the timeframe for authorization. EUA is based on preliminary data and is granted more quickly to address urgent public health needs, whereas full approval demands complete and long-term data, ensuring a thorough evaluation of the vaccine’s profile. For the public, this distinction is important because it affects trust and confidence in vaccines. Full approval often reassures individuals who may be hesitant about vaccines authorized under EUA, as it signifies a more comprehensive review.
In summary, while both EUA and full FDA approval aim to protect public health, they serve different purposes and involve distinct processes. EUA provides rapid access to vaccines during emergencies, while full approval ensures a higher standard of safety and efficacy through extensive evaluation. As of the latest data, the FDA has fully approved a limited number of vaccines, with others remaining under EUA. Understanding these differences helps clarify the status of vaccines and informs decision-making for individuals and healthcare providers alike.
