Vaccine Update: The Impact Of The Moderna Vaccine (Beyond COVID-19)

Sometimes, it takes a terrible global crisis to spurn huge leaps in technology. World War II was arguably the greatest crisis of the modern era, but it helps advance some of the greatest technological leaps in history. We can argue whether those advances were worth all the death and destruction, but there’s no denying that our world wouldn’t be the same without them.

The COVID-19 pandemic isn’t on the same level as World War II, but it is, by most measures, the greatest crisis the world has faced in the past 50 years. It hasn’t just caused hundreds of thousands of deaths and immeasurable amounts of suffering. It has completely disrupted this big, interconnected world that we’ve come to depend on.

We’ve all lost something in this pandemic. Beyond the loved ones who have perished, our entire sense of security and hope has been shattered. We now realize just how vulnerable we were and how inevitable this was. As bad as it is, there is some good coming out of it.

Usually, a crisis like this helps break down the barriers that divided us and hindered progress, technological or otherwise. Never before has the world been more united or engaged in a singular effort. Before 2020, we probably didn’t know much about vaccines or vaccine research. We just knew that Jenny McCarthy tried to be relevant again by protesting them.

That’s changing now. The global effort to create a vaccine for this terrible disease has been watched and agonized over for months. Most recently, we got a much-needed glimmer of hope from Pfizer, who reported that their vaccine is 90 percent effective. I celebrated this news like everyone else.

Then, we got an even greater glimmer of hope from the other vaccine front-runner by Moderna. Not only is their vaccine in the final phase of testing, like Pfizer. It’s even more effective and promises to be easier to store and distribute.

CNN: Moderna’s coronavirus vaccine is 94.5% effective, according to company data

The Moderna vaccine is 94.5% effective against coronavirus, according to early data released Monday by the company, making it the second vaccine in the United States to have a stunningly high success rate.

“These are obviously very exciting results,” said Dr. Anthony Fauci, the nation’s top infectious disease doctor. “It’s just as good as it gets — 94.5% is truly outstanding.”

Moderna heard its results on a call Sunday afternoon with members of the Data Safety and Monitoring Board, an independent panel analyzing Moderna’s clinical trial data.

This is objectively great news in a year when we’ve had precious little of it. These two vaccines may very well be the one-two punch we need to end the COVID-19 pandemic and return to some semblance of normalcy. I would still like to go to a movie theater or baseball game at some point in 2021. These vaccines may make that possible.

However, I’d like to take a moment to speculate beyond this terrible pandemic that has uprooted so many lives. I know that’s not easy to do when the crisis is still very relevant and inflicting plenty of suffering. I still think it’s worth attempting, if only to imagine the better world that emerges from this mess.

That’s because both these vaccines aren’t like your typical flu shots. For one, flu shots aren’t nearly as effective as what Pfizer and Moderna reported. According to the CDC, you’re average flu shot is between 40 and 60 percent effective. That’s still important because the flu can be deadly. Anything you do to reduce it can only further public health, in general.

The problem is the flu shot, and most vaccines like it, are based on old technology. At their most basic, they take a non-infectious or weakened strain of a pathogen and use it to amp up your body’s immunity. It’s crude, but it works. Literally nothing has saved more lives than vaccines.

The problem is that vaccines are notoriously hard to develop. They take a long time to test and an even longer time to approve. Until this pandemic, there just wasn’t much incentive to improve on that process. Now, after these past 8 months, the incentive couldn’t have been greater.

That’s what sped up the development of mRNA vaccines, the technology behind both Pfizer and Moderna. It was reported on as far back as 2018. While this technology isn’t completely new, it has never been developed beyond a certain point. There just wasn’t any incentive to do so. A global crisis changed that.

Very simply, an mRNA vaccine does one better on traditional vaccines by using RNA to develop immunity. It’s not as easy as it sounds. To develop that immunity, it has encode itself with just the right antigen. That way, the antibodies it creates can attack the desired pathogen.

In the case of COVID-19, the mRNA vaccine attacks the distinct spike protein the virus uses to attach to host cells. It’s like a missile targeting a specific individual in a large crowd by locking onto the distinct hat they wear.

This approach has the potential to be much more effective at generating immunity to a particular disease. Instead of trying to mimic a virus, it just gives the immune system the necessary software it needs to do the work. It could potentially revolutionize the way we treat and prevent diseases.

For years, certain viruses like the flu and HIV have confounded efforts to develop a vaccine. Beyond the problems I listed earlier with regards to testing, the difficulty of creating a particular immune response to a particular antigen is very difficult. These viruses mutate and change all the time. With COVID, vaccines do have an advantage because they have a distinct feature.

The challenge for future vaccines against future pandemics is quickly uncovering a particular antigen that the mRNA can be coded for. In theory, all you would have to do is find the one key antigen that’s common to every strain of the virus. While viruses like the flu are notoriously diverse, they can only change so much.

It’s akin to trying to identify an army of spies in a large crowd. They may all look different on the outside, but if they all have the same socks, then that’s what you code for. With some refinements, an mRNA vaccine can stop a pandemic in its tracks before it ever gets beyond a certain point.

That assumes we’ll continue to refine this technology after the COVID-19 pandemic has passed. I certainly hope that’s the case. This year has traumatized entire generations with how much pain and suffering it has inflicted. I sincerely hope that gives plenty of motivation to develop technology like this. That way, we never have to endure a disruption like this again.

To all those who helped develop this technology and these two vaccines, I hope you appreciate the impact you’ll make with this technology. The number of lives they could save is incalculable. Future generations may not remember your names, but they will be forever grateful for this wondrous gift you’ve given them.
