There has been misinformation circulating about mRNA vaccines, including concerns that they interfere with the formation of new DNA. This is not true. mRNA vaccines work by introducing a piece of mRNA that corresponds to a viral protein, usually a small piece of a protein found on the virus's outer membrane. This allows the body to produce the viral protein and mount an immune response without ever being exposed to or infected with the virus. The mRNA does not enter the nucleus of the cell where DNA is located, so it cannot alter or influence our genes.

What You'll Learn
The safety of mRNA vaccines
There has been misinformation circulating online about the safety of mRNA vaccines, with some reports claiming that they are contaminated with excessive levels of DNA. These reports are based on studies that do not meet the scientific rigour expected in pharmaceutical testing and are therefore unreliable.
MRNA (messenger ribonucleic acid) is a molecule in your cells that copies instructions from your DNA and brings them to your ribosomes, which use these instructions to create proteins that make your body work. mRNA vaccines do not enter the nucleus of the cell where DNA is located, so they cannot change or influence our genes. Instead, they work by introducing a piece of mRNA that corresponds to a viral protein, allowing our cells to produce the viral protein and triggering an immune response. This immune response, which produces antibodies, helps to protect us from getting sick from that germ in the future.
While no vaccine or drug is perfectly safe, mRNA vaccines have been studied and worked with for decades, and have been used in cancer research to trigger the immune system to target specific cancer cells. They have also been studied for use with other diseases, including flu, Zika, rabies, and cytomegalovirus (CMV). In the context of COVID-19, mRNA vaccines give the body instructions to make the spike protein, which is found on the surface of the virus that causes COVID-19. This allows the body to learn how to protect against future infection without risking the serious consequences of getting sick with COVID-19.
It is important to note that residual DNA may be present in very small quantities in mRNA COVID-19 vaccines, as it is an approved starting material for many biotechnology products. However, products that use DNA as a starting material have strict limits on the amount of residual DNA that can be present in the final product, and medicines containing residual DNA quantities under these limits have presented a very low risk to human safety.

Misinformation about DNA alteration
There has been a wave of misinformation regarding the safety of mRNA vaccines, with many people concerned that these vaccines can alter DNA. This is not true. The COVID-19 mRNA vaccines do not affect or interact with human DNA.
The misinformation appears to have stemmed from studies conducted by a small number of laboratories that attempted to investigate the amount of DNA in the vaccines. These studies fell short of the scientific rigour expected in pharmaceutical testing and were based on flawed methods. For example, some laboratories used fluorometry, a test known to overestimate DNA levels in the presence of mRNA, which is the main ingredient in the COVID-19 vaccines.
It is important to note that mRNA vaccines do not enter the nucleus of the cell where DNA is located, so they cannot change or influence human genes. The vaccines work by instructing the body to recognise and fight against the virus, triggering an immune response that helps protect against future infection.
While it is true that viruses can change human DNA, this is not the case with mRNA vaccines. The vaccines teach our cells to make a harmless piece of the spike protein found on the surface of the virus that causes COVID-19. After the protein piece is made, our cells break down the mRNA and remove it from the body. This process does not alter our DNA and is simply how our bodies learn to protect against future infection.
Despite the misinformation, it is important to remember that the COVID-19 vaccines have been rigorously assessed and meet high standards for safety, quality, and efficacy.

How mRNA vaccines work
There has been misinformation circulating that mRNA vaccines interfere with the formation of new DNA. However, this is not true. mRNA vaccines work by introducing mRNA (messenger RNA) into your muscle cells. The mRNA contains instructions for making a harmless piece of the spike protein, which is found on the surface of the virus that causes COVID-19. The spike protein is unique to SARS-CoV-2 and is not found on other proteins in the body.
Once the mRNA enters the muscle cells, the cells use it to produce the spike protein. The mRNA is quickly degraded, usually within a few days, and broken down into small, harmless pieces by the cell. The spike protein piece is then displayed on the cell's surface. Our immune system recognizes that the spike protein does not belong there and this triggers an immune response. Our immune system produces antibodies and activates other immune cells to fight off what it thinks is an infection. This immune response helps protect us from getting sick from the virus in the future.
MRNA vaccines do not enter the nucleus of the cell, where our DNA is located, so they cannot alter or influence our genes. The mRNA works outside of the nucleus in a space called the cytoplasm and has not been observed to interact with the nucleus. Any residual DNA present in mRNA vaccines is in very small quantities and does not pose a risk to human safety.
MRNA vaccines have been studied and researched for decades, even before the COVID-19 outbreak, which accelerated their development. They have been studied for use in other diseases such as flu, Zika, rabies, and cytomegalovirus (CMV). mRNA has also been used in cancer research to trigger the immune system to target specific cancer cells.

The development of mRNA vaccines
There has been a lot of misinformation about mRNA vaccines, including the belief that they are not effective against respiratory pathogens and that they are harmful. These beliefs are false. Some people also believe that these vaccines were developed too quickly, but there had been at least two decades' worth of work on these types of vaccines before the COVID-19 pandemic.
MRNA vaccines are a recent development that uses a key part of the pathogen to train our immune system. Instead of using part of a virus or a whole virus like other vaccines, mRNA vaccines use part of a virus's genetic code—the RNA—that encodes for a significant protein on the virus's surface. When that is administered into our body and is taken up by our cells, it allows our body to produce the protein and mount an immune response to it.
In COVID-19 vaccines, the virus is SARS-CoV-2, and the main protein of interest is the "spike" protein on the surface of the virus. The mRNA instructs cells in the body to make a particular piece of the virus's spike protein. When the immune system sees it, it recognizes it as foreign and is then prepared to attack when there is an actual infection.
Despite the benefits and potential of mRNA vaccines, there has been a recent shift in federal vaccine development priorities. The US Department of Health and Human Services (HHS) has announced a wind-down of its mRNA vaccine development activities, including the termination of contracts and cancellation of solicitations. HHS Secretary Robert F. Kennedy Jr. stated that these vaccines fail to protect effectively against upper respiratory infections like Covid and flu, which is contradicted by evidence showing protection against severe disease and death from COVID-19 and promising results against influenza.
The decision to reduce funding for mRNA vaccine development has been met with criticism, with concerns raised about the impact on preparedness and national security for future pandemics and emerging pathogens.

mRNA vaccines vs traditional vaccines
There has been misinformation circulating about mRNA vaccines, including that they contain excessive levels of DNA and can alter human DNA. However, this is not true. mRNA vaccines do not enter the nucleus of cells where DNA is located, so they cannot change or influence human genes. While residual DNA may be present in very small quantities in mRNA vaccines, it is well within the strict limits for biotechnology products, and it does not pose a risk to human safety.
MRNA vaccines are a relatively new type of vaccine that emerged during the COVID-19 pandemic. They work by delivering a snippet of genetic material, specifically messenger RNA (mRNA), that instructs cells to produce a protein unique to a virus, usually the spike protein in the case of SARS-CoV-2. Once the protein is produced, the immune system recognizes it as foreign and mounts a defence, producing antibodies and activating other immune cells to fight off the perceived infection. This immune response helps protect against future infections.
MRNA vaccines have several advantages over traditional vaccines. Unlike traditional vaccines, mRNA vaccines do not contain any whole microbes, alive or dead, so they cannot transmit infections. They also have a shorter manufacturing time and do not require growing large quantities of the virus or bacteria in labs, which can be time-consuming and complex. Additionally, mRNA vaccines have very few risks and have undergone rigorous safety testing.
However, mRNA vaccines also have some limitations. They have specific storage requirements, needing to be kept at very low temperatures to remain stable. Distribution can be more challenging compared to traditional vaccines, which can often be stored at standard refrigerator temperatures. mRNA vaccines may also cause side effects in some individuals, such as pain, swelling, and flu-like symptoms. In rare cases, more serious side effects like pericarditis and myocarditis can occur, but these are typically rare and resolve quickly with rest and medication.
Traditional vaccines, on the other hand, use weakened or dead microbes or pieces of them to stimulate immunity. Live vaccines can provide strong and sometimes lifelong protection but may not be suitable for people with weakened immune systems. Inactivated vaccines, which use dead microbes, generally offer less protection, and booster shots may be necessary. Traditional vaccines have a long track record of safety and effectiveness and are often easier to manufacture at scale once the production process is established.

Frequently asked questions
No, the mRNA vaccine does not enter the nucleus of the cell where DNA is located, so it cannot change or influence our genes.
The mRNA vaccine gives the body instructions to make a small part of the virus so that the immune system can generate tools to fight an infection if it sees the virus again in the future.
All vaccines come with some risks, and mRNA vaccines are no exception. However, the benefits of mRNA vaccines outweigh the risks. For example, the risk of myocarditis is close to 10 times higher with COVID-19 than with the vaccine.
