That’s according to Professor Oh Myoung-don, who leads the central clinical committee for emerging disease control.
He explained Tuesday that when it comes to respiratory diseases, vaccines aren’t a silver bullet.
That’s a view other experts agree with as well.”It’s not easy to replicate the immunogenicity of respiratory viruses and the germs that cause respiratory infections. For example, flu vaccines have an efficacy rate of 60 to 70 percent. Another important fact is that COVID-19 is an RNA virus, so it continues to mutate.”
In fact, the FDA’s approval standard for COVID-19 vaccine is an efficacy rate of 50 percent.
Professor Oh said a vaccine could come as early as next spring.
Until then, people will need to take care of themselves through social distancing and personal hygiene.
As for South Korea raising the level of social distancing, he said he’s not in a position to comment on quarantine measures, but he referred to the WHO Director-General’s comments last Friday that lockdown is not a long-term solution though it may help to suppress transmission and take the pressure off a country’s health system.
Dr. Oh also said it ‘s important for groups of individuals to refrain from singing, exercising, and conversing because this requires breathing through the mouth, which could expose them to more danger than breathing through the nose.
