Gov. Cuomo predicts it will be at least six months before a vaccine is widely available.

He does not know how many doses New York state will get, but the first to receive the vaccine will be senior citizens and those who are immune compromised.

Oxford University and Astra Zeneca are the latest to announce positive results for a COVID vaccine candidate.

They say a double dose of their candidate is up to 90% effective.

Pfizer and Moderna reported last week their vaccines are 95% effective.

While Pfizer and Moderna use messenger RNA, the Astra Zeneca vaccine uses a cold virus to deliver the blue print for us to fight COVID.

It's similar to what is used in wildlife for rabies vaccination.

All three of these vaccine candidates require two shots. However, they're not interchangeable.

To date, no appreciable negative side effects have been reported.
