Having this prototype approach, along with coronavirus research from labs around the world, made it possible for scientists to spring into action when the pandemic hit. Q: Why does it usually take so long to develop a vaccine?

In 1796, the British doctor Edward Jenner demonstrated that an infection with the relatively mild cowpox virus conferred immunity against the deadly smallpox virus. Over the course of 2020, Pfizer and others tested vaccine candidates as hundreds of thousands of people died from COVID-19. For other vaccines, phase 2 studies usually take two to three years. He did his study in 1796, and although he did not invent this method, he is often considered the father of vaccines because of his scientific approach that proved the method worked. The research is now being used to develop an RSV vaccine, the vaccine Graham had thought might be his legacy.

A group that did not get the vaccine is usually included in phase as a comparator group to determine whether the changes in the vaccinated group are attributed to the vaccine, or have happened by chance. More research needs to be done to see how long immunity to COVID-19 and the vaccines lasts. Historically, the timelines for bringing vaccines to bear on other pathogens show a much longer arc than 18 months.

There is a third production technology for flu vaccines that was approved for use in the U.S. market in 2013 and that involves using recombinant technology external icon.Recombinant flu vaccines do not require having a candidate vaccine virus (CVV) sample to produce. In this post, we focus on how long it takes to develop and manufacture vaccines—particularly those designed to protect against COVID-19. But it traditionally has taken 5-10 years to get a new vaccine. This is why success requires “many shots on goal,” says Thomas, noting there have been more than 200 COVID-19 vaccines in development.
