Vaccines are designed to help our bodies develop immunity to a virus without us having to get the illness. In the case of COVID-19, vaccines have been instrumental in reducing the impact of the pandemic, preventing severe illness and death, and protecting against long COVID. However, some individuals have reported chronic symptoms that develop shortly after receiving a COVID-19 vaccine, a condition referred to as post-vaccination syndrome (PVS). While vaccines are generally safe and effective, some people have concerns about their potential impact on natural antibodies. There has been a claim that the COVID-19 vaccine wipes out the body's natural antibodies, but this has been debunked by experts.

COVID-19 vaccines help the body develop immunity to SARS-CoV-2
The presence of the spike protein triggers an immune response, as the immune system recognizes it as foreign. This response includes the production of antibodies specifically targeting the spike protein, as well as the activation of other immune cells to fight off what it perceives as an infection. This process is similar to how the body responds to an actual COVID-19 infection, but without exposing the individual to the risks of the disease.
After the immune system is activated, the spike protein and mRNA are broken down and removed from the body. However, the body retains a supply of "memory" T-lymphocytes and B-lymphocytes, which remember how to fight the SARS-CoV-2 virus in the future. This immune memory is what provides long-lasting protection against COVID-19. It is important to note that the development of immunity typically takes a few weeks, and side effects from the vaccine are not indicative of its effectiveness.
Contrary to misinformation circulating, COVID-19 vaccines do not wipe out the body's natural antibodies. This claim was debunked by Dr. Otto Yang, a UCLA researcher specializing in infectious diseases. He explained that our immune system is designed to handle numerous infections throughout our lifetime, and if each new infection wiped out existing antibodies, the immune system would not function properly.

Vaccines trigger an immune response to protect against illness
Vaccines are designed to trigger an immune response to protect against illness. They do not wipe out the body's natural antibodies. Instead, vaccines help the body learn how to defend itself from disease without the dangers of a full-blown infection. The active ingredient in all vaccines is an antigen, which causes the immune system to begin producing antibodies. Antibodies are like soldiers in the body's defence system, each trained to recognize one specific antigen.
When the human body is exposed to an antigen for the first time, it takes time for the immune system to respond and produce antibodies specific to that antigen. In the meantime, the person is susceptible to becoming ill. Once the antigen-specific antibodies are produced, they work with the rest of the immune system to destroy the pathogen and stop the disease.
Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. This weakened version will not cause the disease in the person receiving the vaccine, but it will prompt their immune system to respond much as it would have on its first reaction to the actual pathogen. This initial immune response may cause mild symptoms for a day or two, such as a fever, chills, or tiredness. This is because the body is acting as if it is fighting a mild form of the germ, not because it is infected.
After the body produces antibodies in response to the vaccine antigen, it also creates antibody-producing memory cells. These memory cells remain alive even after the pathogen is defeated, allowing the body to respond much faster and more effectively if exposed to the same pathogen in the future. This is how vaccines provide long-lasting protection against disease.
It is important to note that no single vaccine provides 100% protection, and even vaccinated individuals can sometimes get infected. However, vaccination significantly reduces the risk of serious illness or death by preparing the body's immune system to fight the infection.

Antibody levels typically peak within two to four weeks of vaccination
Vaccines are designed to generate an immune response to help protect an individual from illness. In the case of COVID-19 vaccines, they help our bodies develop immunity to the SARS-CoV-2 virus without us having to get the illness. The vaccines introduce mRNA into our muscle cells, which then produce a harmless piece of the spike protein found on the surface of the virus. Our immune system recognizes that this protein does not belong, triggering the production of antibodies and activating other immune cells to fight off what it thinks is an infection. This process typically takes a few weeks, and antibody levels usually peak within two to four weeks of vaccination.
The specific timeline for antibody development can vary depending on the type of vaccine and individual factors. For example, with the flu vaccine, it typically takes about two weeks for the body to develop antibodies, according to the CDC. However, the protection offered by the flu vaccine may last for about six to eight months, depending on individual factors and the specific flu strains circulating in a given season.
It is important to note that the COVID-19 vaccine does not wipe out the body's natural antibodies. This claim has been debunked by experts such as Dr. Otto Yang, a UCLA researcher specializing in infectious diseases. Our immune system is designed to deal with numerous infections throughout our lifetime, and if it wiped out pre-existing antibodies with each new infection, it would not function effectively.
The presence of symptoms after receiving a COVID-19 vaccine may indicate a robust immune response. Studies have shown that experiencing symptoms such as fatigue, malaise, chills, and headaches after vaccination was associated with higher neutralizing antibody concentrations. Therefore, the side effects of vaccination can be seen as a positive sign of the body's immune system mounting a protective response.
Overall, the development of antibody levels and the duration of protection provided by vaccines can vary, but it is important to get vaccinated to protect ourselves and others from illness. The COVID-19 vaccine, in particular, offers protection against the virus without the risks associated with getting sick with COVID-19.

Vaccines do not destroy pre-existing antibodies
There is no evidence that vaccines destroy pre-existing antibodies. Vaccines help our bodies develop immunity to viruses without us having to get the illness. Different types of vaccines work in different ways to offer protection, but with all types of vaccines, the body is left with a supply of "memory" T-lymphocytes and B-lymphocytes that will remember how to fight the virus in the future.
The claim that the COVID-19 vaccine wipes out the body's natural antibodies is false. This claim was made in a TikTok video that stated the American Red Cross no longer accepts convalescent plasma from those who have received a COVID-19 vaccine because the vaccine wipes out natural antibodies. However, the American Red Cross has refuted this claim, stating that the decision to stop collecting convalescent plasma was due to having stockpiled a sufficient supply to meet the needs of COVID-19 patients.
Dr. Otto Yang, a UCLA researcher specializing in infectious diseases, explained that the COVID-19 vaccine does not destroy the body's pre-existing antibodies. Our immune system is evolved to deal with numerous infections throughout our lifetime. If every time we got a new infection, we wiped out everything we had before, our immune system wouldn't work.
Dr. Sabrina Assoumou, Assistant Professor of Medicine at Boston University School of Medicine, also confirmed that "vaccine-induced immunity does not 'wipe out' any natural antibodies that are developed prior to vaccination." She added that recent studies show that vaccination after natural immunity, or "hybrid immunity," appears to provide robust immunity. Therefore, individuals who were previously infected with SARS-CoV-2 should still get vaccinated.

Vaccines are designed to generate antibodies that target the virus
Vaccines are designed to generate antibodies that target viruses. For example, the COVID-19 vaccine is designed to generate an immune response to help protect individuals from illness. Similarly, the Rift Valley fever virus vaccine is designed to generate proteins that the host's immune system can use to arm itself against a viral infection.
In the case of COVID-19, the vaccine contains a harmless piece of the spike protein, which is found on the surface of the virus. Once inside the body, the vaccine uses the cells' machinery to produce this spike protein. Our immune system then recognises that the protein does not belong there, triggering the production of antibodies and activating other immune cells to fight off what it thinks is an infection. This process ultimately helps protect against future infection with the virus that causes COVID-19, without the vaccinated individual ever having to risk the potentially serious consequences of getting sick.
Vaccines have been incredibly successful in the past, such as in the case of smallpox, which has been completely eliminated thanks to vaccines. Other viral diseases that have been brought under control with vaccines include measles, mumps, rubella, chickenpox, yellow fever, rabies, and hepatitis B.
It is important to note that vaccines do not wipe out the body's natural antibodies. This claim has been debunked by experts, who assert that vaccine-induced immunity does not override or change the immune system's existing antibodies. In fact, research shows that vaccination after natural immunity can even enhance the immune response.

Frequently asked questions
No, the COVID-19 vaccine does not wipe out your body's natural antibodies. It is designed to generate an immune response to help protect you from illness.
There was a claim that the American Red Cross would not accept blood plasma donations from people who had received the COVID-19 vaccine because it supposedly wiped out the body's natural antibodies. However, this claim has been debunked, and the American Red Cross does accept plasma donations from vaccinated people.
The COVID-19 vaccine works by introducing mRNA into your muscle cells. The cells then make copies of the spike protein, which is found on the surface of the SARS-CoV-2 virus. Your immune system recognizes that the spike protein does not belong there and begins to produce antibodies to fight off the perceived infection.
Some vaccines provide long-lasting protection, such as the measles vaccine, which can protect you for a lifetime. However, other vaccines, like the flu and COVID-19 vaccines, may require booster shots because the viruses they target can change or mutate frequently.
Common side effects of the COVID-19 vaccine include pain or swelling at the injection site, headache, chills, and fever. These side effects are normal signs that your body is building protection. Serious adverse events after vaccination are rare.
