WASHINGTON – The world crossed the one-million mark of confirmed COVID-19 cases this past week. With untold millions more possible in the months to come, scientists are committed to making a vaccine.
There’s a lot about COVID-19 that scientists still don’t know. They don’t know entirely how it is spread. And without proven treatments or vaccines, good hygiene and staying away from other people are the only known methods of prevention.
Dr. Peter Hotez at Baylor College of Medicine started working on a coronavirus vaccine in 2003, during the outbreak of SARS, but after that, research funds dried up.
Hotez expects more coronaviruses to develop and spread. Some may be more benign that COVID-19, some far deadlier.
“Pandemics for coronaviruses have become a new normal. That we saw with SARS in 2003. We saw it in MERS s in 2012, and now this one. So we can expect a new major coronavirus every decade.
