Two things I thought of tonight:
1) If the vaccine doesn't lead to lasting immunity then at what point will they say we need a booster? I'm assuming they will be following the participants of the clinical trials. The vaccine was capable of preventing 90-95% of cases in the study period, but what if that number drops down. At what point do we need a booster? Is it 75%? Is it 50%? The J&J vaccine is apparently only 70% effective, yet I'm sure it'll be an option, so I'm sure there is some threshold where one vaccine will be used over others when supplies are bountiful, or they will say we need a booster of some type. I'm curious because most things don't last forever. Like birth control might be 99% effective for a given event or year or whatever, but in a ten year span the actual odds of not getting pregnant while on the pill is not 99%; it might be 60%. Similarly, if this thing starts to wane then what will be the cut off criteria. I'm not entirely sure. We have booster shots for other vaccines that we received as a child that may be twenty years down the road. We have the yearly flu shot because the flu evolves. I'm curious how this will go.
2) I said it above, but we need to be thankful for those who participated in the trials. Many people did it for personal reasons, but I'm sure many did it because they wanted to serve their country. It reminds me the Minnesota Starvation Experiment done during WWII. If you are not familiar then they are worth checking out.
