What is the scientific basis for the new requirement that patients be followed for sixty days after their last shot for FDA vaccine approval?

Question

Every week the vaccine is delayed another 5,000 Americans, many of them nurses will die from Covid-19.

Is this delay just to keep Donald Trump from announcing the vaccine is ready before Election Day?

Answer 1

Vaccines development takes years, not months.  We are on an accelerated track now, companies are just that, they are not magicians.

Answer 2

  “There is no worse mistake in public leadership than to hold out false hopes soon to be swept away.” — Winston Churchill

 Antibody dependent enhancement (ADE) is a major obstacle in vaccine development.  It means some vaccine attempts make the disease WORSE.  If you plan to give 300,000,000 people a vaccine, it better be SAFE.

Answer 3

The vaccine was never going to be ready before the election, any one who told you otherwise was just lying and giving false hope.

It's being developed at record pace as it is, forcing the process to go faster is just dangerous.

Answer 4

The basis is that it gives us enough time to find out if there are serious side effects. We've already seen progress halted on some vaccines due to serious reactions occuring. Believe it or not, medicine is more complicated than hurting the reelection chances of one below average politician.

Answer 5

If someone's going to follow me around, they better leave me alone from 7PM-8PM - that's my "special time".
