Spanish and Russian Airlines Recommending Vaccinated People Not To Travel...

We are starting to come full circle. Now airlines in Spain and Russia are warning people who have been vaccinated should not travel. Indeed, COVID-19 vaccinated people can be excluded from air travel! That was the headline of a Russian online news portal. There are a number of news articles coming out a warning that vaccinated people may not be allowed to travel because of the danger of blood clots in the mile-high atmosphere. In Spain, the same thing is appearing. This has raised concerns that are the objective of this vaccine to prevent travel?

Even the American CDC has on their site a warning about blood clots when traveling more than 4 hours on airplanes:

More than 300 million people travel on long-distance flights (generally more than four hours) each year.1 Blood clots, also called deep vein thrombosis (DVT), can be a serious risk for some long-distance travelers. Most information about blood clots and long-distance travel comes from information that has been gathered about air travel. However, anyone traveling more than four hours, whether by air, car, bus, or train, can be at risk for blood clots.
