![]() ![]() ![]() The vaccine contains the following ingredients: Pfizer BioNTech COVID-19 vaccine has been generated entirely in the laboratory, outside of living cells, formulated in lipid nanoparticles. The mRNA is then normally degraded within a few days. The protein then acts as an intracellular antigen to stimulate the immune response. mRNA vaccines use the pathogen’s genetic code as the vaccine this then exploits the host cells to translate the code and then make the target spike protein. Pfizer BioNTech COVID-19 vaccine is a nucleoside-modified messenger RNA vaccine (mRNA) vaccine. The different stages of the vaccine development process have also overlapped such that manufacturing was already underway whilst the clinical trials were still ongoing, further speeding up the process. Making a vaccine is expensive and funding is a common issue, but as the pandemic increased with worldwide spread so did the resources made available to research teams. That earlier research provided a head start for rapid development of vaccines to protect against infection with the novel coronavirus SARS-CoV2, the virus that causes COVID-19. How did they make the vaccine so quickly?Ī misconception is that work on the vaccine began when the pandemic started scientists had already begun research for coronavirus vaccines during previous outbreaks caused by related coronaviruses such as SARS (Severe Acute Respiratory Syndrome) and MERS (Middle East Respiratory Syndrome). ![]()
