Pfizer's Vaccine Technology
Pfizer’s vaccine is based on a novel technology called messenger RNA (mRNA). This technology has never been used before to develop a vaccine and has been developed over the last decade. mRNA technology works by delivering genetic instructions to the body’s cells to make proteins that mimic a virus, in this case, the novel coronavirus. The body’s immune system then recognizes the protein as a foreign invader and produces antibodies to fight it.
Pfizer's Vaccine Advantages
Pfizer’s vaccine has several advantages over other vaccine candidates. First, it does not require the use of live or weakened virus, meaning it can be manufactured quickly and safely. Second, the mRNA technology used by Pfizer allows the vaccine to be stored at much colder temperatures than other vaccines, which makes it easier to transport and distribute. Finally, the vaccine is said to be highly effective, with the company announcing that it is 95% effective in preventing Covid-19.
Pfizer's Vaccine Challenges
Despite its advantages, Pfizer’s vaccine also has some challenges. For one, the vaccine is only approved for adults over the age of 16, meaning it will not be available to younger age groups. Additionally, the vaccine must be stored at extremely cold temperatures, which may make it difficult to distribute in some parts of the world. Finally, the vaccine is still being tested and approved, so it is not yet available to the public.
