The COVID-19 pandemic has led to a dramatic loss of human life worldwide, and continues to present an unprecedented challenge to public health, food systems, and the world of work.

The economic and social disruption caused by the pandemic has been devastating, and for many, it has felt like a never ending nightmare.

With the approval of the Pfizer-BioNTech and Moderna vaccine in early December, and recently the Johnson & Johnson vaccine, people have been given a new sense of profound hope.

The Pfizer vaccine requires two doses, and has been authorized for use for people aged 16 and older. Similarly, the Moderna vaccine requires two doses, but differs in who can receive it since it has only been approved for use in people aged 18 and older.

Both vaccines have shown extraordinary, and essentially equivalent degrees of efficacy. With the Pfizer vaccine having an efficacy rate of 95%, and the Moderna vaccine being 94.1% effective at preventing COVID-19 after the second dose.

The Johnson & Johnson vaccine on the other hand only requires one dose, and has been authorized for use for people aged 18 and older. It has been shown to be 66% protective against moderate to severe COVID-19 infection, and has an 85% effective rate in protecting against severe disease.
