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.

B117 COVID Variant

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.

B1351 COVID variant

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.

P1 COVID variant

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.

Visualized: The Global Syringe Shortage Threatening Vaccine Efforts

The Global Syringe Shortage Threatening Vaccine Efforts

Routine vaccination saves millions of lives every single year, according to the World Health Organization (WHO).

But even though global vaccination coverage is improving, closing the gap in immunization has led to skyrocketing demand for syringes—which is forecast to result in a major shortage that could make matters worse.

In the above infographic from NuGen Medical Devices, we explore the factors leading to the syringe shortage and take a look at the company’s innovative needle-free solution that could play an important role in closing the immunization gap.

The Immunization Gap

Even before the COVID-19 pandemic, millions of people around the world struggled to get access to routine vaccinations.

In fact, as of 2019 more than 19 million children around the world were considered to be “zero-dose” which means that they did not receive any routine vaccinations.

Moreover, when the COVID-19 pandemic hit, global immunization dropped even further with 25 million children missing out on routine vaccines in 2021 alone.

Why is Immunization So Important?

Vaccinations prevent against over 20 life-threatening diseases and save between 2-3 million deaths per year, making them—as the WHO describes—the foundation of healthcare systems and an indisputable human right.

As countries work through a backlog of vaccinations to close the immunization gap that has worsened since the pandemic, demand for syringes has significantly increased.

The Result: A Global Syringe Deficit

In 2022, the WHO warned that we could see a shortage of up to 2 billion syringes if manufacturing can’t keep up. This could result in the severe disruption to routine vaccinations and promote unsafe recycling of syringes in order to administer vaccines.

But the issue goes far beyond a supply shortage of syringes. COVID-19 has brought conventional syringe vaccines into sharp focus, with many criticizing the challenges associated with them.

The Challenge
Vaccine Hesitancy:
1 in 10 Americans have an extreme fear of needles and therefore will avoid vaccination.
Affordability:
The cost of essential syringe vaccination makes them inaccessible for people living in low and middle income countries.
Cost of Logistics:
Geographical constrains, a lack of infrastructure, and the need to keep vaccines at sub-zero temperatures prevent them from reaching those who need it the most.
Biohazardous Waste:
7.8 billion needles are discarded in the U.S. every year.
The Solution
Reduce Fear:
Needle-free devices remove the fear of syringes.
Reduce Costs:
Needle-free devices are lower in cost per injection compared to conventional needles.
Minimizes Cold Chain:
NuGen MD’s next generation powder injectables minimize the need for a cold chain (keeping vaccines at sub-zero temperatures) entirely.
Sustainable Needles:
Needle-free technology reduces environmental waste significantly.

With conventional needles facing so many challenges, it’s no surprise that investors are taking interest in viable alternatives. What’s more, these alternatives don’t just apply to vaccinations, they can also work for people with diabetes, dentists, and pet care.

Enter Needle-free Devices from NuGen MD

Needle-free devices have the potential to bridge the gap in immunization amid the global syringe shortage, solve some of the key challenges limiting vaccine uptake, and more importantly, benefit the lives of millions of people.

How Do They Work?

NuGen’s needle-free devices use a simple spring-loaded mechanism which uses pressure to release the liquid drug and penetrate the skin. In less than one-tenth of a second, the drug is dispensed more safely and evenly compared to needle syringes. It’s also virtually painless and leaves no mark on the skin.
