Comment on Are mRNA Vaccines for COVID-19 helpful or harmful? by Sean Pitman.
1. I assume some defective mRNA strands and lipid layers can be generated during the myriad of involved complex chemical processes. Do we understand percentage of defective nanoparticles / mRNA strands? Does process include QA that somehow reduces or eliminates potentially harmful defects. What is risk of defective mRNA strands that could encode for harmful proteins? Any other associated risks here that I am not addressing?
Given that the mRNA sequences in the Pfizer and Moderna vaccines are synthetically produced, I would say that there are very few defective mRNA sequences. And, when it comes to producing proteins based on these few defective sequences, the additional risk from such defective sequences for the human body would be, effectively, zero. In fact, a few slight variations in the protein sequence for the spike protein would only result in slight variations in the immune system response. And, producing such slight variations are already part of how our human immune system is programmed to work – automatically producing slight variations in the antibodies produced against a particular type of foreign antigen, for example.
2. How much independent review occurred with these vaccines? Is the Global Advisory Committee on Vaccine Safety the only body that reviewed. Do scientiests get hands-on and eyes-on access to the actual chemical processes to verify what is happening (in vitro and in vivo), or are they just provided with white papers and reports for review?
A great many scientists were involved in the production and review of the mRNA vaccines. These vaccines, how they work, and their effects on human biochemistry are very well known by a great many scientists who work in this field of immunochemistry. There are no fundamental secrets here.
3. Some papers and FAQs claim the generated viral “spike protein” is presented on the cell surface. Some of your dialogue here seems to indicate that this is not the case. Which is it? How is it presented? Is it presented in a variety of ways?
Here are a few diagrams that illustrate what’s happening within different cells of the body where the mRNA sequences are decoded and presented:
Mechanism of action of mRNA vaccines. 1. The mRNA is in vitro transcribed (IVT) from a DNA template in a cell-free system. 2. IVT mRNA is subsequently transfected into dendritic cells (DCs) via (3) endocytosis. 4. Entrapped mRNA undergoes endosomal escape and is released into the cytosol. 5. Using the translational machinery of host cells (ribosomes), the mRNA is translated into antigenic proteins. The translated antigenic protein undergoes post-translational modification and can act in the cell where it is generated. 6. Alternatively, the protein is secreted from the host cell. 7. Antigen protein is degraded by the proteasome in the cytoplasm. The generated antigenic peptide epitopes are transported into the endoplasmic reticulum and loaded onto major histocompatibility complex (MHC) class I molecules (MHC I). 8. The loaded MHC I-peptide epitope complexes are presented on the surface of cells, eventually leading to the induction of antigen-specific CD8 + T cell responses after T-cell receptor recognition and appropriate co-stimulation. 9. Exogenous proteins are taken up DCs. 10. They are degraded in endosomes and presented via the MHC II pathway. Moreover, to obtain cognate T-cell help in antigen-presenting cells, the protein should be routed through the MHC II pathway. 11. The generated antigenic peptide epitopes are subsequently loaded onto MHC II molecules. 12. The loaded MHC II-peptide epitope complexes are presented on the surface of cells, leading to the induction of the antigen-specific CD4 + T cell responses. Exogenous antigens can also be processed and loaded onto MHC class I molecules via a mechanism known as cross-presentation. (Link)
Now, The mRNA-1273-encoded prefusion stabilizes the S protein (Moderna Vaccine) consists of the SARS-CoV-2 glycoprotein with a transmembrane anchor and an intact S1–S2 cleavage site. The presence of the transmembrane anchor would seem to enable some of the spike proteins to remain attached to the surface of the cell that produced them, such as a muscle cell, but would still be recognized as “foreign” by the immune system.

Are mRNA Vaccines for COVID-19 helpful or harmful?
The following commentary by organic chemist Derek Lowe is also helpful in understanding this question (December 4, 2020):
Bob Wachter of UCSF had a very good thread on Twitter about vaccine rollouts the other day, and one of the good points he made was this one. We’re talking about treating very, very large populations, which means that you’re going to see the usual run of mortality and morbidity that you see across large samples. Specifically, if you take 10 million people and just wave your hand back and forth over their upper arms, in the next two months you would expect to see about 4,000 heart attacks. About 4,000 strokes. Over 9,000 new diagnoses of cancer. And about 14,000 of that ten million will die, out of usual all-causes mortality. No one would notice. That’s how many people die and get sick anyway.
But if you took those ten million people and gave them a new vaccine instead, there’s a real danger that those heart attacks, cancer diagnoses, and deaths will be attributed to the vaccine. I mean, if you reach a large enough population, you are literally going to have cases where someone gets the vaccine and drops dead the next day (just as they would have if they *didn’t* get the vaccine). It could prove difficult to convince that person’s friends and relatives of that lack of connection, though. Post hoc ergo propter hoc is one of the most powerful fallacies of human logic, and we’re not going to get rid of it any time soon. Especially when it comes to vaccines. The best we can do, I think, is to try to get the word out in advance. Let people know that such things are going to happen, because people get sick and die constantly in this world. The key will be whether they are getting sick or dying at a noticeably higher rate once they have been vaccinated.
No such safety signals have appeared for the first vaccines to roll out (Moderna and Pfizer/BioNTech). In fact, we should be seeing the exact opposite effects on mortality and morbidity as more and more people get vaccinated. The excess-death figures so far in the coronavirus pandemic have been appalling (well over 300,000 in the US), and I certainly think mass vaccination is the most powerful method we have to knock that back down to normal.
That’s going to be harder to do, though, if we get screaming headlines about people falling over due to heart attacks after getting their vaccine shots. Be braced.

I know that various European countries, including the Netherlands, Denmark, and Spain, have reported outbreaks of COVID-19 in mink pelt farms – leading to the culling of more than a million animals. From laboratory experiments, it’s also clear that ferrets (a relative of the mink) are also readily infected with the “novel coronavirus”. Aside from this, however, I’m not aware of any “issues” with animal experiments regarding COVID-19 in particular. However, in 2008 there was an interesting experiment involving ferrets that were given the flu vaccine against the H1N1 virus – who then became sicker once exposed to the live virus as compared to those ferrets that weren’t vaccinated. The reason for the effect was unclear, and Skowronski, the lead author, urged other research groups to take up the question.
“Skowronski likened the mechanism to what happens with dengue viruses. People who have been infected with one subtype of dengue don’t develop immunity to the other three. In fact, they are more at risk of developing a life-threatening form of dengue if they are infected with one of the other strains.”
Skowronski called the second theory the infection block hypothesis. Having a bout of the flu gives the infected person antibodies that may be able, for a time, to fend off other strains; flu shots only protect against the strains they contain. So under this theory, people who didn’t have flu in 2008 because they got a flu shot may have been less well armed against the pandemic virus.”
While interesting, such an effect has not been identified in the animal or human trials for the mRNA vaccines against COVID-19. Also, subsequently updated flu vaccines to the H1N1 strain haven’t had this problem either (Link).
Are mRNA Vaccines for COVID-19 helpful or harmful?
Regarding the recent situation where 23 nursing home patients died in Norway following vaccination the mRNA vaccines of Pfizer and/or Moderna (given to 30,000 people so far), these patients were all over the age of 80, were very frail. It is also somewhat difficult to determine a link in this particular population between the vaccine and any other potential cause of death – since around 400 nursing home patients die in Norway every week. However, at this point, it is not ruled out that adverse reactions occurring within the first days following vaccination (such as fever and nausea) may contribute to a more serious course and fatal outcome in patients with severe underlying disease and general frailty.
Steinar Madsen, medical director with the Norwegian Medicines Agency, said: “We are not alarmed by this. It is quite clear that these vaccines have very little risk, with a small exception for the frailest patients.” (Link)
The Norwegian Institute of Public Health said concluded that “for very frail patients and terminally ill patients, a careful balance of benefit versus disadvantage of vaccination is recommended.” (Link)
Consider this also in the light that more than 30% of nursing home residents are likely to die if an outbreak of COVID-19 occurs. So, weighing the risks and benefits of taking the vaccine vs. being exposed to a potential COVID-19 outbreak seems to weigh heavily in favor of taking the vaccine – with the exception, perhaps, of those who are already very frail.

“For such a time as this”
Again, while a good diet and great health are important, this just isn’t enough to effectively prevent disease during a viral pandemic. As I’ve already explained, this is why Ellen White took the smallpox vaccine herself and advised the others who were with her to do the same. Such vaccines are, in fact, part of the most effective ways of “keeping well” rather than “curing disease” after the fact…
“For such a time as this”
It’s a serious mistake to compare the advances of modern medicine to the prophecies of Ellen White regarding the activity of Satan during the Last Days – where Satan appears as a powerful angel of light, even taking on the form, appearance, and attitude of Christ (making fire come down from the sky and healing the sick and speaking words of grace and comfort in order to deceive the world). Are you really suggesting that the modern mRNA vaccines against COVID-19 are actually part of these final “benevolent” works of Satan? How is this anything but extremist nonsense? – a rejection of a gift of God to help humanity by claiming that it is actually the work of Satan himself? This sort of thing reminds me of this passage in Matthew:
But when the Pharisees heard this, they said, “It is only by Beelzebul, the prince of demons, that this fellow drives out demons.” (Matthew 12:24)
You do realize, after all, that Ellen White took the smallpox vaccine herself during an outbreak? as did her son William White? and that she recommended that all of the others who were with her at the time take the vaccine as well? (Link) Contrary to some claims that I’ve heard regarding her actions here, it wasn’t that the vaccines in her day were less risky or more “pure” than they are today. They were actually riskier compared to modern vaccines, but still far far less risky compared to getting the actual infection itself. That’s why she took the vaccine. She also recommended that missionaries in areas infested with malaria take quinine – that we should, “do the best we can” in such situations (Link). When medications are beneficial and are appropriate, they may be used. When surgery is called for, it should be performed. In 1905 Ellen White wrote:
“Those who seek healing by prayer should not neglect to make use of the remedial agencies within their reach. It is not a denial of faith to use such remedies as God has provided to alleviate pain and to aid nature in her work of restoration…. God has put it in our power to obtain a knowledge of the laws of life. This knowledge has been placed within our reach for use. We should employ every facility for the restoration of health, taking every advantage possible, working in harmony with natural laws… It is our privilege to use every God-appointed means in correspondence with our faith, and then trust in God,… If there is need of a surgical operation, and the physician is willing to undertake the case, it is not a denial of faith to have the operation performed… Before major surgery, the entire body is saturated with a powerful and, in a sense, harmful drug [the anesthetic], to the point of complete unconsciousness and to complete insensibility. By the same token, after surgical procedures, the physician may find it necessary to administer medications that almost certainly include drugs to give relief and prevent the patient from lapsing, from sheer pain, into a state of surgical shock and, in some instances, possible death.” (Link)
Ellen White also recognized that blood transfusions could save lives. She herself had radiation therapy — X-ray treatments at Loma Linda for a skin problem. In short, she was not opposed to reasonable advances of modern medicine, accepting them as gifts of God, not sinister plots of Satan. We should remember her example in this regard and no turn away from the gifts of God that He has granted us through the advances of modern medicine.
Updating the SDA Position on Abortion
I appreciate your position, but as stated, without any details or counterargument, I’m afraid it’s just not very helpful to me (or anyone else)…
“Essentially all the administrators, staff and faculty on our campus, including the pastors on our campus already know where I stand. I have never kept any secrets. I have to laugh when I see you say that I am upset because you ‘blew my cover.’ There was no cover to blow.” – Bryan Ness
You’re not the main problem here. I’d have no problem with you personally and what you personally believe at all except that you are a professor in an Adventist school – Pacific Union College.
It’s this school who presents itself as being in line with the primary goals and ideals of the Adventist Church, when it really isn’t. I have friends of mine who have gone to PUC and talked to the leadership about sending their children to PUC. They’ve specifically asked about the situation at La Sierra University and asked the PUC leadership and heads of departments what their position is on teaching the theory of evolution as “the truth” – and if the teachers at PUC support the SDA position on origins and other issues? They were told that PUC does not condone what happened at LSU and that the professors at PUC are fully in line with the SDA position on origins and all of the other fundamental positions of the church.
Of course, you know and I know that this just isn’t true. You, for one, publically speak and teach against the church’s position on origins as well as human sexuality. This reality is not being presented by the leadership of PUC to the parents of potential PUC students. This reality simply isn’t being advertised to the general church membership at all. What PUC should be advertizing to parents and the church membership at large is,
“Yes, we do maintain professors who teach our students that the church’s position on various fundamental doctrinal issues is in fact wrong and should be changed to reflect the more popular secular position on these topics.”
That’s what it should be telling everyone, but this just isn’t what is being done.
I am attacking no one… Since when is a difference of views an attack on the church?
Since it was placed as one of the church’s “fundamental beliefs” by the church (Link). When you publically publish an article stating that the Church’s position is clearly mistaken and should be changed, that’s an attack on the church’s position.
And of all the issues facing the church, same-sex marriage hardly rises to the level of a “primary goal and ideal.”
The SDA Church has chosen to describe the definition of marriage as being between one man and one woman as one of the “fundamental” messages to spread to the world – as one of the fundamental reasons for its very existence…
Now, you call what you’re doing, not an “attack”, but a “plea for compassion”. However, your plea for compassion is presented as a clear statement that the church’s position is absolutely mistaken – that the church’s position is not at all “compassionate” or even biblical. Now, you may be very honest and sincere in your views here, but that doesn’t mean that you’re not attacking the church’s position in a very real and fundamental way. The fact is that you are making a very clear attack on the church’s position while accepting money from the church as a representative who is supposed to be supporting the church as a paid employee.
Why do you want to cause such people so much pain?
That’s not my goal. However, if a person wants to know what the Bible has to say about what they are doing, I’m not going to pretend that the Bible has nothing to say when the Bible does in fact have something to say. If what the Bible says “causes pain” to a person living in what the Bible says is a “sinful” lifestyle, that’s between them and God. The very same thing is true of me and my own sinful tendencies. If what the Bible says about what I’m doing causes me pain, I can either respond to that by ignoring what the Bible has to say, or I can ask God for help in changing my ways.
Jesus himself said that He did not come to bring peace to those who are living in rebellion against God’s ideals for humanity, but a “sword” (Matthew 10:34). The denial of self and what we naturally want to do given our fallen condition, in order to follow God and what He calls us to do, is often quite painful indeed. That doesn’t mean it’s not the best path to follow. There simply can be no peace between God and those who wish to hang onto what God has said to give up. God does not condemn the sinner for being born broken, but He does warn those who refuse to accept His offer of help to escape their broken condition that, eventually, such refusals of help will not end well for those who are determined to follow their own way.
Yet, these professors get very upset when their actions are made public – when they can no longer hide what they are doing from the church at large. – Sean Pitman
Uh, I have never hidden my support and affirmation for LGBTQ+ individuals, and any parent who wanted to know my views on the subject could easily look up what I’ve written, or they could just plain ask me. I openly acknowledge where I stand on these issues on social media too. Essentially all the administrators, staff and faculty on our campus, including the pastors on our campus already know where I stand. I have never kept any secrets. I have to laugh when I see you say that I am upset because you “blew my cover.” There was no cover to blow.
You have not simply let people know what I advocate, you have attacked me personally and impugned my motives and personal spiritual path. You are causing pain not just to me, but to the very people I am trying to comfort and encourage. Your words are not just being seen by the legalistic and judgmental people like yourself, but by parents of LGBTQ+ children and those LGBTQ+ individuals themselves, many of whom are likely already heavily weighed down with self revulsion and depression. And you are doing this for who’s good?
And you wonder why I might be angry and upset? As hard as it is for me to do, I have daily decided to pray for you and those like you that God would soften your heart and show you the grave wounds you are inflicting on God’s beloved. I pray God will help you find compassion and clearer spiritual insight.
Do you really think it’s a “little thing” when our own professors are attacking the primary goals and ideals of the church from the inside? – Sean Pitman
I am attacking no one. You act as if you have not even read my article. I did suggest in there that I think it is time for the church to change and affirm same-sex marriage, but that is not an attack, that is a plea for compassion, a plea that the church return and study this topic again, and I laid out the reasons I think it is fully warranted that we do so. Since when is a difference of views an attack on the church? And of all the issues facing the church, same-sex marriage hardly rises to the level of a “primary goal and ideal.” You are inflating the importance of this topic. the only place where same-sex marriage really rises to a high level of importance is when you are an LGBTQ+ person contemplating marriage, or are the parent, relative or friend of an LGBTQ+ person. Why do you want to cause such people so much pain?
