COVID-19 vaccines set to break global sales records

This article as well as many others confuses meaning of "infection" and "disease". This is a very important distinction. The Pfizer press release says it is 90% effective at preventing the disease [1], it does not say the vaccine prevents infection.

COVID-19 = the name for the disease cased by the virus

SARS-CoV-2 = the name of the strain of coronavirus that causes the COVID-19 disease.

This vaccine is 90% effective at preventing the disease, but while infected, you have replicating RNA in your body and will be contagious.

Whilst I do welcome a vaccine, I do worry about the safety of the vaccine. We have been told my medical professionals months and months ago that a vaccine is likely to take years, not just to develop a vaccine but also for testing and trails.

Now we're hearing it might be early next year? I understand that the focus to prepare a vaccine might have been greater. I do hope I can have a level of confidence in the drug being successful with little side effects if any.

The article briefly mentions it - but

1) 19.50 is what the United States has agreed to pay. It's unlikely the same price point other countries can / are willing to afford.

2) Rollout may be harder than expected.

3) If some of the other vaccines work, no certainty of what would be picked.

4) Since the amount of people taking it now grow exponential fold - we may hear of unexpected side effects (hopefully not).

OP's comment pointing out the distinction between "infection" and "disease" has been downvoted to death without an apparent explanation. Could someone elaborate on why? On the surface this looks like an important point to raise.

Is it because an antiviral vaccine that prevents a disease must by definition also prevent infection?

Oh, so GLAD the most pressing matter of this pandemic is being so quickly addressed. PROFITS!

It still seems like society is throwing far too little money at this problem. It would be worth paying twice as much just to speed up the pace of global vaccination by two months.

According to the article, Pfizer plans to sell 1.3 billion doses in 2021 and the price (for two required doses) is USD 19.50. This means USD 25,350,000,000.00 in sales. And it also says: "Pfizer's CEO has already disclosed that the vaccine will be sold at a "very marginal profit." " EDIT: corrected calculation
