Which Covid Vaccine Is Best

Pfizer-BioNTech Vaccine

The Pfizer-BioNTech vaccine is a messenger RNA (mRNA) vaccine that teaches the body to make a protein that is similar to the spike protein of the SARS-CoV-2 virus. The spike protein is what the virus uses to enter cells. The vaccine is 95% effective at preventing symptomatic COVID-19 and 94% effective at preventing severe COVID-19. It is also effective against the Delta and Omicron variants of the virus. The Pfizer-BioNTech vaccine is approved for use in people 16 years of age and older.

Pros

* High efficacy * Effective against variants * Approved for use in people 16 years of age and older

Cons

* Can cause side effects, such as fever, chills, and fatigue * Requires two doses * Requires storage at ultra-low temperatures

Moderna Vaccine

The Moderna vaccine is also an mRNA vaccine that works in the same way as the Pfizer-BioNTech vaccine. It is 94% effective at preventing symptomatic COVID-19 and 98% effective at preventing severe COVID-19. It is also effective against the Delta and Omicron variants of the virus. The Moderna vaccine is approved for use in people 18 years of age and older.

Pros

* High efficacy * Effective against variants * Approved for use in people 18 years of age and older

Cons

* Can cause side effects, such as fever, chills, and fatigue * Requires two doses * Requires storage at ultra-low temperatures

Johnson & Johnson Vaccine

The Johnson & Johnson vaccine is a viral vector vaccine that uses a modified adenovirus to deliver the SARS-CoV-2 spike protein into cells. The vaccine is 66% effective at preventing symptomatic COVID-19 and 85% effective at preventing severe COVID-19. It is also effective against the Delta variant of the virus. The Johnson & Johnson vaccine is approved for use in people 18 years of age and older.

Pros

* Single dose * Effective against variants * Approved for use in people 18 years of age and older

Cons

* Lower efficacy than mRNA vaccines * Can cause side effects, such as fever, chills, and headache * Has been linked to a rare blood clotting disorder
