Pfizer vaccine | History, Facts & Statistics
How did Pfizer delivery a covid vaccine in world record timing? Buckle up for this episode of Sunday Scaries as we learn the history and facts around the Pfizer vaccine.
According to the World Health Organisation (WHO), the average time to develop and make a vaccine publicly available until now has been 16 years. In fact, the vaccine that comes remotely close in matching the Covid-19 pace is the mumps vaccine, which took close to 4 years to get all necessary permissions and licensing. So far, only smallpox has been declared officially eradicated by vaccination.
What aided scientists in developing a Covid-19 vaccine in record time is the fact that it was not required to be made from scratch. Scientists had begun making vaccines for SARS and MERS, which belong to the coronavirus family, during their outbreaks in 2003 and 2012, respectively, only to abandon the efforts when the outbreaks petered out.
