With the climbing coronavirus numbers, there's worldwide excitement on the announcement by Pfizer and BioNTech that their vaccine candidate outperformed expectations.

In the first interim analysis, the vaccine was found to be more than 90% effective at preventing COVID-19.

That's far better than the 50% the FDA said it needed to see.

However, don't throw out your masks just yet.

Dr.  Eli Rosenberg, an epidemiologist and assistant professor at UAlbany School of Public Health is also on Gov. Cuomo's vaccine distribution advisory task force.

He says the 90% prevention figure from this Phase 3 study means if 100 people are exposed to coronavirus only 10 would become sick and that gets us well on the way to taming this viral beast.

However, we don't yet know about long-term protection and if everyone, despite age or underlying health conditions get the same immune response.
