Mrna infographic7/26/2023 As a result, these trials tend to take much longer to complete. mRNA technology has also been explored for treating cancer however, clinical trials for treatments are different than those for preventions, and often if a patient has the choice of taking a proven treatment or one that is “in development,” they will opt for the former (for obvious reasons). HIV and influenza mRNA vaccines did not work, meaning that people who got the vaccine were not better protected than those in the placebo group. For example, Zika vaccines could not finish being tested because the outbreak receded. The reasons that no previous mRNA vaccines were approved had to do with the pathogens and circumstances, not the safety of the mRNA approach. One that, although it had been in development for about 20 years prior to the COVID-19 pandemic, had never previously been used in an approved vaccine. The other category of COVID-19 vaccines, commonly referred to as “mRNA” vaccines, used a new approach. The protein-based COVID-19 vaccine (Novavax) is also in this latter category (single protein) as its antigenic component is the spike protein from SARS-CoV-2 virus, the virus that causes COVID-19. Single proteins important to the infection and subsequent immune response (like hepatitis B, HPV and shingles vaccines).Whole viruses that have been treated, so they can’t reproduce (like hepatitis A and polio vaccines).Whole, weakened viruses (like chickenpox and measles vaccines).Historically, viral vaccines have included: For the vaccine to work, our immune system has to be introduced to some part of the pathogen that it will come into contact with during an infection. AntigensĪll vaccines will contain an antigenic component because this is the part of the vaccine to which we make an immune response. So, let’s take a look related to COVID-19 vaccines. However, not all vaccines contain all five of these categories. Vaccines, including those for COVID-19, typically contain specific categories of ingredients, including antigens, adjuvants, stabilizers, preservatives, and residual manufacturing byproducts. Instead, we will focus on the mRNA vaccines (Pfizer and Moderna) and the protein-based vaccine (Novavax). (as of mid-May 2023), information about that vaccine will not be included. Since J&J/Janssen vaccines are no longer available in the U.S. Specifically, what is contained in COVID-19 vaccines? And, related to this, what is NOT contained in COVID-19 vaccines. However, we also realize that people still have questions, so this month we thought we would address one of those. With regard to COVID-19 vaccine safety, while many rumors continue to circulate, the reality is that globally more than 13 billion people have been vaccinated, and we know how the vaccine works, so we are not expecting any long-term consequences that have yet to be “discovered.” Indeed, those among us with the most robust protection appear to be individuals who were both infected and vaccinated. Second, even if someone has had COVID-19 infection, the vaccine is still beneficial. First, although the numbers of people getting hospitalized or dying from COVID-19 have decreased dramatically, most of those who are severely affected (i.e., hospitalized or die) are previously unvaccinated. Regarding the need for COVID-19 vaccine, two points are important. Often those in this third group have concerns about the safety of the vaccine or their need for it. People in high-risk groups who have not received a current booster.At this point in time, three groups are of particular focus when it comes to getting vaccinated against COVID-19: With world-renowned advanced technology platforms and rich production experience, GenScript provides synthesis services for gene, plasmid, peptide, protein, etc., available in several vaccine production grades, including GMP.Although the COVID-19 public health emergency came to an end in May 2023, the COVID-19 vaccine continues to be recommended for virtually everyone. The importance of vaccines was highlighted during the outbreak of COVID-19, when developing a vaccine was considered one of the most important ways to end the pandemic. More than 20 high-risk diseases can be currently prevented through vaccination.Īdditionally, since the cost of vaccination is far lower than the high medical expenses incurred after the disease occurs, vaccines are a health investment with one of the highest rates of return. Vaccines have played a major role in protecting human health as one of the main means of controlling infectious diseases. Today marks World #AIDS Vaccine Day! It serves as an important occasion to underline the urgency and importance of education in our communities about the vital role of HIV vaccine research.
