COVID-19 could become a seasonal virus showing up each year with other coronaviruses, according to a B.C. vaccine expert.
Dr. Manish Sadarangani, director of the Vaccine Evaluation Centre at B.C. Children’s Hospital, said there were four coronaviruses that usually circulate each year in B.C. that all lead to mild colds. Because symptoms are mild, no one had tried to create a vaccine for them, Sadarangani said.
The two severe forms of coronavirus that existed before COVID-19 — SARS and MERS — were not wide spread and so no mass vaccine was created.
“While people have been working on the MERS and SARS coronaviruses, none of them have ended up in widespread use,” he said. “We are really starting a little bit from the beginning.”
