These symptoms are the expected and healthy reactions to the vaccine and often subside in few days. Most people have mild side effects like arm pain, aches, chills and fever after vaccination. The mRNA vaccines cannot cause disease because they do not contain a live virus. Fact: The mRNA vaccines cannot give you COVID-19 Therefore, chances of altering host DNA are highly unlikely. After being read, these mRNA vaccine molecules degrade quickly through normal cellular processes.ĬOVID-19 mRNA vaccines produce only the spike protein and can’t produce the enzymes that facilitate the host-cell integration. The mRNA instructions are used to manufacture the spike protein, which the body recognizes as not belonging, and this evokes an immune response. The messenger RNA, or mRNA, delivered from the vaccines enters the cell but not the nucleus. Fact: Vaccines have no effect on recipients’ genetic materialĭNA is located inside the nucleus of a cell. This meant that once the vaccines were proved safe and effective there was a large stockpile ready to distribute to the public. Because of the urgency of the COVID-19 pandemic, manufacturing and commercial-scale production of these vaccines started at the same time as the human safety clinical trials. This typically happens after phase 3 efficacy trials have been completed. Third, most of the costly and time-consuming part of vaccine development is scaling up manufacturing and commercial production, and ensuring quality control. Second, funding and partnerships from government and private firms allowed many of the clinical trial phases to occur in parallel, rather than in series, which is typical testing design. Scientists were able to apply this familiar technology to the SARS-CoV-2 virus immediately after its discovery. There are several reasons.įirst, mRNA technology has been studied for other viral diseases – Zika virus, rabies virus, respiratory syncytial virus – for the past few years. The development, clinical trials and approval occurred faster than seen with previous vaccines. The Pfizer-BioNTech vaccine reduced disease by 95% and the Moderna vaccine reduced disease by 94% after volunteers completed two doses. More than 90,000 people volunteered for these vaccine trials. Moreover, the approved mRNA vaccines have undergone rigorous testing and clinical trials demonstrating safety and efficacy in people. The mRNA technology that was used in the Pfizer/BioNTech and Moderna vaccines has existed for more than a decade and is not new in the vaccine development field. Fact: Vaccines were rigorously tested and found to be safe Here are some of the facts behind some of the common myths that we have heard about the COVID-19 mRNA vaccines from patients, friends and family members. If the American population is to achieve herd immunity, it is important to start dispelling myths so that when there is widespread access to the vaccine, people will not hesitate to get their shot. Many experts estimate that between 70% and 90% of the population must be vaccinated to block the spread of the virus and reach herd immunity, which occurs when enough individuals are immune to a disease that it prevents its spread. This is often because they have heard incorrect information about the vaccine or its effects. It’s the misinformation about the COVID-19 vaccines.ĭemand for vaccine currently exceeds supply, but there are many people who are either unsure whether they should take the vaccine or staunchly against it. One of the biggest barriers standing in the way of ending the pandemic isn’t medical or logistical.
