I am wondering why do more companies are still doing Covid-19 vaccine trials when there are already successful vaccines in the market and already being widely used? What is the gain to company?
COVID is a permanent fixture of the Earth now. It's like measles or malaria. You'll never have a day in your life where COVID doesn't exist.
Ten years from now, COVID will still be a problem - an active, pressing problem that kills people - for the USA. The exact strain causing the problem then probably won't be one that exists today, but a strain will exist and it will be a problem.
COVID will be in your routine inoculations. Babies will get it at 6 months, 12 months and 18 months.
Other countries will be much worse. The poor countries of the world won't have real vaccinations until 2022 or 2023.
If a breakthrough strain that mostly resists existing vaccines happens, we basically have to start over. Anyone with an approved vaccine that DOES work against a breakthrough strain gains an immediate license to print money.
There continues to be a tremendous market opportunity for providing COVID vaccines, and will be for the foreseeable future.
