Why I’m Optimistic About The Development of A COVID-19 Vaccine
By Ken Perez, vice president of healthcare policy, Omnicell
While proper hand hygiene, personal protective equipment, social distancing, testing, and therapeutics are all valid and useful measures in the battle against SARS-CoV-2, the virus that causes COVID-19, a safe, effective vaccine is the only path to normal. It is the ultimate game-changer. As one reader recently wrote to The Buffalo News, “Without a COVID-19 vaccine, there is no Hollywood ending.”
It certainly won’t be easy. In general, over 90% of vaccine candidates fail, and vaccines usually take several years, not months, to develop. Despite 33 attempts at a vaccine for Severe Acute Respiratory Syndrome (SARS), which spread worldwide in a few months from China in 2002, no SARS vaccine exists today.
Similarly, for Middle East Respiratory Syndrome (MERS), which started in Jordan in April 2012 and spread to a total of 27 countries, all 13 vaccine candidates to date have failed.
As of this writing, the novel coronavirus has infected 5.6 million persons and caused some 350 thousand deaths across over 200 countries. It is highly transmissible—spread by even asymptomatic individuals—and it is “wily,” as it has mutated over a dozen times. In short, it constitutes an epochal challenge for all of humankind.
Nevertheless, there are reasons to be optimistic about the chances for successful development of a COVID-19 vaccine.
