Explained: The 3 Major COVID-19 Variants
Explained: The 3 Major COVID-19 Variants
As billions of people gear up for widespread vaccination against COVID-19, another issue has reared its head. Three major COVID-19 variants have emerged across the globe—and preliminary research suggests these variants may be cause for concern.
But what makes them different from the original strain?
The following visualizations answer some key questions, including when these variants were first discovered, how far they’ve spread worldwide, and most importantly, their potential impact on the population.
Some Context: What is a Variant?
Before diving in, it’s important to understand why viruses mutate in the first place.
To infect someone, a virus takes over a host cell and uses it to replicate itself. But nature isn’t perfect, and sometimes, mistakes are made during the replication process—those mistakes are called mutations.
A virus with one or more mutations is referred to as a variant. Most of the time, variants do not affect a virus’s physical structure, and in those instances, they eventually disappear. However, there are certain cases when a mutation impacts part of a virus’s genetic makeup that does change its behavior.
According to the U.S. Centers for Disease Control (CDC) a change in behavior can alter:
- Rate of transmission
- Deadliness
- Ability to potentially infect someone with natural or vaccine-induced immunity
Preliminary research has detected some of these changes in the three major COVID-19 variants—B.1.1.7, B.1.351, and P.1.
The 3 Major COVID-19 Variants
The three major variants emerged at different times, and in different parts of the world. Here’s an overview of each variant, when they were discovered, and how far they’ve spread so far.
B.1.1.7
The B.1.1.7 variant was detected in the UK in the fall of 2020. By December 2020, it had spread across the globe, with cases emerging across Europe, North America, and Asia.
Currently, the variant has been reported in roughly 94 countries.
Early research suggests it’s 50% more transmissible than other variants, and potentially 35% more deadly than the standard virus. Luckily, studies suggest that some of the existing vaccines work well against it.
B.1.351
In October 2020, the second major variant was discovered—B.1.351. It was first identified in South Africa, but by end of the year, it had spread to the UK, Switzerland, Australia, and Japan.
There are approximately 48 countries with reported cases, and research suggests several of the existing COVID-19 vaccines may not be as effective against this variant.
P.1
The P.1 variant was the last to arrive on the scene.
It was first discovered in January 2021, when Japan reported four cases of the variant, which was found in travelers who had arrived from Brazil.
Approximately 25 countries have reported cases of the P.1 variant, and early research suggests this variant is not only more contagious, but could also have the ability to infect people with natural immunity who had already recovered from the original strain.
Still Early Days
While there have been preliminary studies showing a dip in vaccine effectiveness, some experts emphasize that it’s too early to tell for certain. More data is needed to gain a deeper and more accurate understanding.
In the meantime, experts are emphasizing the importance of following our current public health strategies, which include physical distancing, vaccination, washing your hands, and using masks.

The Cost of an EpiPen in Major Markets
This visualization compares EpiPen prices around the world, with the U.S. having the highest prices by far.

EpiPens are auto-injectors containing epinephrine, a drug that can treat or reverse severe allergic reactions, potentially preventing death.
The global epinephrine market was valued at $1.75 billion in 2022 and is projected to reach $4.08 billion by 2030. North America represents over 60% of the market.
EpiPens, however, can be prohibitively expensive in some regions.
In this graphic, we present estimated EpiPen prices in major global markets, compiled by World Population Review and converted to U.S. dollars as of August 2023.
Why are U.S. Prices so High?
The U.S. stands out as the most expensive market for EpiPens, despite over 1 million Americans having epinephrine prescriptions. After Mylan (now part of Pfizer) acquired the rights to produce EpiPens in the U.S. in 2007, the cost of a two-pack skyrocketed to $600, up from about $60.
Country | Price (USD) |
---|---|
🇺🇸 U.S. | 300* |
🇯🇵 Japan | 98 |
🇩🇪 Germany | 85 |
🇨🇦 Canada | 80 |
🇫🇷 France | 76 |
🇦🇺 Australia | 66 |
🇬🇧 UK | 61 |
🇮🇳 India | 30 |
*Per unit cost. Commonly sold as a two-pack, meaning total cost is equal to $600
Former Mylan CEO Heather Bresch defended the price hikes to Congress, citing minimal profit margins. Mylan eventually settled with the U.S. government for a nine-figure sum.
Notably, EpiPens are available at a fraction of the cost in other developed countries like Japan, Germany, and Canada.
Making EpiPens More Affordable
Efforts to improve EpiPen affordability are underway in several U.S. states. For instance, the Colorado House approved a $60 price cap on epinephrine, now under review by the state Senate.
Similar measures in Rhode Island, Delaware, Missouri, and Vermont aim to ensure insurance coverage for epinephrine, which is not currently mandatory, although most health plans cover it.
