The difference with COVID is that early studies suggest that memory B cells , a type of immune cell produced by the bone marrow, proliferate even after NAb levels have dropped.
These memory cells sentinel for the virus' return and start churning out "new" NAbs if and when they do. There is growing evidence that the immune system produces an ample supply of memory B cells even in people with mild or asymptomatic disease. A November study published in The Cell reported that memory B cells capable of producing COVID NAbs were found in people who experienced mild infection and that their numbers appeared to increase over time.
As such, even if NAbs are decreased, memory B cells may have the ability to quickly replenish levels. This may not fully avert infection but may help reduce the risk of symptomatic infection. When news of waning NAb levels was first reported in the media, many assumed this to mean that immunity was somehow "lost" over time.
The assumption was likely premature, in part because there haven't been the waves of COVID reinfections that many had predicted. With the exception of a Hong Kong man who was found to be infected twice with a different strain of COVID, there are few other strongly documented cases. Even in that instance, the man was asymptomatic the second time around, suggesting that the primary infection may have afforded protection against illness.
Moreover, antibodies, as important as they are, only play a part in the body's overall defense. Other immune cells, called T cells , are recruited during an infection to seek-and-destroy infected cells or disrupt the virus' ability to replicate. In addition, a subset of T cells, called CD4 helper T cells , are responsible for activating memory B cells should the virus return.
These can persist for years. And, even though their numbers may be small, these CD4 helper T cells still have the ability to launch a robust immune defense. This is evidenced in part by the results of the Moderna vaccine trial. Clinical studies have shown that the Moderna vaccine provokes a high and sustained NAb response 90 days after the two-dose series.
Although the memory response remains unknown, the presence of CD4 helper T cells in study participants suggests that the vaccine may afford longer-lasting protection. Still, there are many who believe that sterilizing immunity should remain the ultimate goal of vaccine development.
They argue that, while the immune response from the Pfizer and Moderna vaccines appears strong, no one really knows for sure how long the response will last. And, this could be a problem since asymptomatic infections still have the potential to infect others. By contrast, a vaccine that affords complete sterilizing immunity stops infection before it occurs and prevents further spread of the virus.
As millions are slated to be vaccinated with the Pfizer and Moderna vaccines worldwide, increasing focus is being placed on several protein-based COVID vaccines in early phase 2 development. These protein-based candidates, made from harmless fragments of COVID called spike proteins , are paired with a secondary agent called an adjuvant that activates the immune system.
Although protein-based vaccines take longer to develop than the messenger RNA mRNA models employed by Pfizer and Moderna, they have a long history of use and an excellent record for safety and effectiveness. A protein-based vaccine from the manufacturer Novavax was reported to have achieved sterilizing immunity in primates. Just like your internship mentors developed your personal skill sets, hospitals and clinics may rely upon you to train others.
In addition to helping your employer, becoming an expert can help you work your way up the ladder to become, say, a sterile processing supervisor which also comes with a much higher average salary. A major benefit of sterile processing programs is that they can be finished between 4 to 9 months, depending on your personal schedule. This is one of the quickest allied health training routes that gets you into an entry-level job fast.
Each school has their own requirements, so be sure to do some research about their application, financial processes, and their accreditation from a US Secretary of Education agency. Most programs require a high school diploma or its equivalent and have minimum age requirements.
Though few states require licensing, most employers prefer to hire certified sterile processing technicians. Search Directions Contact. Programs Programs.

The CDC recommends healthcare personnel and residents of longer term care facilities should be offered the first doses, the following groups include frontline essential workers and people 75 and older. The CDC also says once you get your vaccine you may experience pain and swelling. As well as fever, chills and tiredness, which are all common.
Information on the vaccine is always changing, and we want to keep you up to date with the latest information. Contests Newsletters Apps.
Watch Now. Alex Crescenti ,. But many have died from disease. You have to weigh the risk vs benefit, which will be different depending on your circumstances age, where you live, current health issues, what your lifestyle is, what you eat, your environment etc. You should be able to choose which vaccines to take with full informed consent, or be able to choose not to take a vaccine, again with being fully informed of your risks and benefits.
And whatever your decision will be, it should be respected. Again, thank you. I also thank the Weston Price foundation for their efforts in sharing the information on good nutrition.
While I am choosing to take the Corona vaccine in the spring or in summer, I will continue to drink raw milk, enjoy butter without guilt, support local farmers and ranchers who raise their animals humanely and grow vegetables and fruits organically we live in Florida. Stay healthy, my friends. Regarding legal liability for vaccines, manufacturers did have full legal liability until They manufactured vaccines for decades.
The injuries and lawsuits SHOULD have motivated them and spurred them into action to implement the highest safety standards going forward in the name of public health. Instead, the mftrs lobbied public health agencies and Congress and threatened to stop making vaccines. Removing legal liability from vaccine manufacturers removes incentive to ensure the highest product safety standards. Now, vaccines are a cash cow with minimal legal and marketing expenditures.
They acknowledged this in district court 3 years ago. I am curious to know what discussions the medical community is having regarding the possibility of pathogenic priming or advanced disease enhancement with the COVID vaccine since it was an issue with the SARS vaccine and the animal trials were skipped this time? My in-laws in their late 70s are choosing not to get vaccinated because of the information coming out of the Weston Price Foundation.
My father-in-law has type 2 diabetes, had a stroke last year, and has congestive heart failure. Is it really your belief that he should not receive a vaccination? We are extremely concerned for his health. This is truly a life or death situation.
For the most part they are healthy. As a family, we made a choice for them to self quarantine. No public exposure. No visitors inside the house. I get their groceries and take them to any Doctor appts.
My son takes care of any repairs needed. My son and I both take the necessary precautions. So far so good. Knock on wood. From main stream media, our govt, and our public health officials, the public hears only what the vaccine producers say about the safety and efficacy of their product. When you have done this, fear and confusion will evaporate and you will know what your decision will be regarding the vaccine.
Hi Amy. I am not a doctor and I do not give medial advise, however I can tell you what I have learned from my research. First of all, despite tremendous efforts, no vaccine has ever come to fruition for any of the other 6 coronaviruses identified in humans. This is what Dr. This type of disease enhancement cause animals and humans to suffer hyper-immune responses including inflammation throughout the body and particularly in the lungs.
It has also caused death. It is also important to remember that the trials have been conducted for a very short period of time and very few elderly people have been included. None of the Pfizer trial participants suffered from the health concerns your father-in-law suffers from, yet there was a fold increase in serious adverse events in healthy older adult volunteers after they received the second dose of experimental vaccine.
The bottom line is, there are no completed clinical trials for COVID vaccines and we have no idea what will happen to the general population let alone the most vulnerable after the second dose of vaccine is administered and time as gone by.
This article is a must read. I hope this is helpful information and that you and your family choose to do extensive research before making any decisions regarding COVID vaccination. I believe we can be sure a few deaths and serious side effects are under-reported.
HOWEVER the great blessing in this scenario so far is the relative absence of severe side-effects compared to what we feared. For this I am grateful. I prefer gratefulness to fear. Anyone else? I would like to give you my analysis of the danger of mRNA vaccines that I have not seen anywhere yet. My thirty-five year career started with chemical industry experience with very sensitive purification techniques.
From that background in organic and inorganic chemistry I moved to the IT hardware and software industry. My experience in industrial production and purification techniques tells me that absolute purity is not possible. The encased mRNA in the US vaccines are guaranteed to have impurities and damaged material that will enter and cause cells to produce something other than the intended spike proteins. Very small changes in RNA can have dramatic effect on what is produced.
What I am saying is beyond allergic reactions to vaccine additives like ethylene glycol as recently reported in the media.
The damaged impure mRNA is guaranteed to have a moderate to terrible effect on millions. I would easily predict cancers, infertility, and birth defects, not immediately but starting in two to three years. As physicians and researchers start to notice the increasing numbers the corporate controlled media will try to provide cover by calling it Russian disinformation or conspiracy theory but the numbers will continue to increase.
I am not against traditional vaccines except that some have dangerous stabilizers and other additives. But with mRNA vaccines millions are being kept ignorant and marched directly into tragedy.
My warning is especially for the young that still have most of their lives ahead of them. As far as adverse allergic reactions to the mRna, has anyone thought about all the prescription drugs a large portion of the population now take on a daily basis?
Some people take multiple. Have there been any research articles into that? Does anyone know? Far more important, will be the numbers of young takers destined to spend decades in nursing homes as pitiful helpless shufflers. Should the numbers be reversed and non-takers be flooding the cemeteries or homes, then we will know the vaccine was a good idea. My life is far too precious to gamble until the results are in.
Sadly, either way, the Big Pharma shareholders and their trillions in loot will be long gone. The Safety and Efficacy Study of the Pfizer vaccine set out to determine safety and efficacy. Efficacy: How many people out of 18, people, test positive after taking 2 vaccines compared to 18, who do not. According the cited BMJ article by Peter Doshi, there would not be enough data to only analyze severe cases.
That does not, in any way, mean that the impact is minor. The study is fundamentally limited to the point where no statistical meaning could ever be derived from it. With only patients, no control group or double-blind measure, or the dozens of other controls that go into a valid study, it cannot make any claim.
