As the joy over Pfizer (NYSE: PFE) and BioNTech‘s ((NASDAQ: (BNTX))) vaccine announcement ebbs, some harsh realities have began to set in. The vaccine candidate — whereas a fabulous feat of science — has some hurdles to beat if it will fulfill the promise of serving to finish the worldwide pandemic.
Past regulatory approval, there are manufacturing, logistical, and efficacy inquiries to cope with. With the world ready, there isn’t a query human ingenuity will prevail. However getting this vaccine out to billions of individuals may not be the stroll within the park the markets appear to imagine. Let us take a look at a number of points the potential Pfizer vaccine must overcome to reward shareholders and save lives.

Pfizer seems to have handed essentially the most troublesome technical barrier; the corporate has developed a vaccine that appears to be 95% efficient in stopping COVID-19. Nonetheless, that is solely an interim evaluation — an early look. Whereas there have been greater than 40,000 contributors within the total trial, this reported efficacy is predicated on 170 people. I will be curious to see whether or not the efficacy fee holds up when extra knowledge is revealed.
We additionally do not understand how lengthy this vaccine will stay efficient. Whereas vaccines are usually not authorized except they shield individuals for at the very least a yr, these aren’t regular occasions. Pfizer has utilized for emergency use authorization from the FDA, which ought to come within the subsequent few weeks. For the reason that company has famous that any vaccine with better than 50% efficacy can be authorized, I do not see Pfizer having a problem with approval.
Messenger RNA — the tactic utilized by Pfizer‘s vaccine candidate — could be very unstable, and no mRNA vaccines have but been authorized for human use. Creating mRNA in specifically designed chrome steel bioreactors requires sterile circumstances with a exact temperature and humidity. This instability is without doubt one of the causes the vaccine have to be stored so chilly.
As you may think, it is so much simpler to make a small batch of mRNA for a medical trial than it’s to make lots of of tens of millions of doses for full-scale distribution. Within the distribution area, at the very least, Pfizer has gotten some assist. In May, the corporate agreed to buy vials fabricated from Valor Glass, a container made by Corning (NYSE: GLW) that is specifically designed and created for vaccines. Valor is a wholly new class of glass that stops contamination and permit high-volume manufacturing strains to stream easily, with out jams.
Earlier within the pandemic, Pfizer confronted a delay in changing manufacturing tools and getting extra uncooked materials to make the vaccine. The corporate has addressed these issues and has up to date manufacturing strains within the U.S. and Europe.
The subsequent problem would be the customized luggage that line the bioreactors the place vaccines are produced. These luggage act like liners in gradual cookers; they’re eliminated when batches are performed, eliminating the necessity to sterilize the bioreactors after every batch. The scarcity of those luggage, which has lasted a number of weeks and counting, was addressed in October when Operation Warp Velocity injected $31 million into the bag producer — which is now a part of Danaher (NYSE: DHR) — to ramp up manufacturing. Though the funding was wanted, the constraint stays.
Pfizer was cautious to notice that its vaccine candidate was not a part of Operation Warp Velocity, and in an analogous method, the corporate has chosen to distribute its personal vaccine relatively than depend on the federal government. Given the advanced necessities, it’s doubtless for the perfect. Nearly everybody now is aware of that the Pfizer vaccine have to be stored at temperatures colder than any ever recorded within the U.S. (even Alaska!) — destructive 94 levels Fahrenheit.
To keep up the temperature because the vaccine is shipped from both the Wisconsin or Michigan manufacturing websites, Pfizer developed a supercooled suitcase. The “pizza field,” as they name it, permits temperature and placement to be tracked always. Utilizing dry ice, the vaccine is stored on the crucial temperature for 10 days as soon as sealed. The circumstances can solely be opened twice per day for lower than three minutes at a time. Every case holds between 1,000 and 5,000 doses and may take 4 days in transit. Meaning every web site with a case must administer about 850 doses per day earlier than the vaccine destabilizes. Extra dry ice might be added to increase the timeline, however there’s a scarcity of that too.
The kind of freezers wanted to retailer a vaccine at destructive 94 levels Fahrenheit usually are not low cost, nor are they simple to search out. The freezers can price about $20,000 and the present wait is about six weeks. Leasing house is an choice, however chilly storage makes up solely 2% of the general warehouse market and the emptiness fee is lower than 5%. It is simply not one thing that has garnered loads of funding.
Whereas there’s a sudden want for a lot of freezers to deal with many vaccines, hospitals may discover it troublesome to spend the cash figuring out they may by no means use the tools once more. Add within the uncertainty about what the federal authorities can pay for, if something, past the vaccine itself, and you may see the dilemma. Fortunately, Walgreens (NASDAQ: W(BA)) and CVS (NYSE: CVS) have stated they’re prepared and in a position to retailer the Pfizer vaccine. Given the practically 20,000 places between them, this one reality may overcome most different limitations the vaccine faces, and ease buyers’ minds.
As soon as the vaccine has been developed, examined, manufactured, shipped, and saved, it must be administered. As soon as once more, the Pfizer vaccine raises the bar when it comes to issue. The vaccine have to be combined on the administration web site with a sterile liquid — often water — and given inside six hours of making the answer. For the reason that vaccine can be shipped in circumstances with a excessive quantity of doses, rural communities may not have the inhabitants, or infrastructure, to manage a case of doses whereas nonetheless chilly. Due to this, residents in rural areas who need the vaccine may must journey to a extra centralized location to get it. No less than in long-term care and nursing properties — the place practically a 3rd of COVID deaths have occurred — there’s a plan. CVS has stated it stands prepared to start administering a vaccine to these at-risk populations as quickly as one is authorized.
However there are causes for cautious optimism
Earlier this yr, Pfizer agreed to promote 100 million doses of its vaccine candidate to the U.S., with an choice for 500 million extra. I am assured the logistical challenges can be found out and any present shortages can be addressed. Science has made an incredible leap ahead in creating an mRNA vaccine, and the issues that come up will doubtless be ones which were solved earlier than, albeit maybe on a smaller scale.
Though a lot of the worldwide dialogue revolves round how to verify much less rich nations have entry to the vaccine, the sensible concerns span the globe. Consider Australia: Whereas it’s a developed economic system, the nation lacks the manufacturing functionality to create an mRNA vaccine by itself soil, in addition to the cold-storage chain to keep up the deep-freeze temperatures required for the long run. If that nation goes to distribute the Pfizer vaccine, it must determine easy methods to get the drug from the American Midwest into the arms of its residents in lower than 10 days.
Regardless of the challenges, the U.S. is lucky to be the place we’re with respect to the vaccine. I consider the prevailing cold-chain infrastructure, and Pfizer‘s foresight, will permit the corporate to get doses to residents all through a lot of the U.S. That ought to be sufficient to bolster shares and make the corporate one of many winners of the general vaccine race. It’s on my radar as a stock to purchase, however I will be far more bullish once I see individuals lining up on the native clinic or drug retailer for doses of the vaccine. Solely then can buyers begin taking a look at 2021 because the yr that life went again to regular.
