The Different COVID-19 Vaccines

As of today, January 12, 2021, there are currently two vaccines that have received FDA approval. These are both mRNA vaccines including: 

• ​Pfizer-BioNTech COVID-19 vaccine 
• Moderna’s COVID-19 vaccine 

According to the CDC, mRNA vaccines teach our cells how to make a protein – or even just a piece of a protein – that triggers an immune response inside our bodies. That immune response, which produces antibodies, is what protects us from getting infected if the real virus enters our bodies. 

There are also three additional vaccines in Phase 3 of clinical development in the US, including: 

• AstraZeneca’s COVID-19 vaccine 
• Janssen’s COVID-19 vaccine 
• Novavax’s COVID-19 vaccine​
