One of the problems with a vaccine is going to be who owns it. And who can afford it.
The other thing is how effective it will be.
I saw a doctor talking about reinfection and how antibodies don't last very long in some people.
The flu vaccine is renewed every year, rather than a vaccine like measles which lasts a lot longer.
That's going to be a logistical issue too. How do you vaccinate everyone. Who gets the vaccine first? Who is more valuable versus who is more at risk.
Then you have production issues. Especially if various places are shut down or struggling with the effects of the disease or there are items in short supply. All these things have the potential to slow down roll out.
There was talk of a vaccine being available in 12 months. That's now being pushed back to more like 18 months.
That's all without considering that proper clinical trials into the side effects are going to be difficult (if not impossible) to do in that time.
If children aren't dying of the disease, would you want your child to be given a relatively untested vaccine? Big questions there.
And of course 18 months is going to be far too long for a lot of people. By then it will be too late with the first wave of COVID-19, most likely to be in full swing throughout the globe.
It's difficult to see an alternative to a massive crisis looming everywhere at this point. It is just all about ability to manage the crisis rather than stop it now, I fear.
