Your theory and conjecture are interesting. Since MRNA based vaccines were never used before 2021, your record of historically data is woefully inadequate.
If you are trying to predict the future, unless your name is Nostradamus, I have zero confidence in your future predictions. But feel free to give me a DATE or Month or even a YEAR when these bad effects from that 1/2 cc of clear liquid used to jab me will manifest itself. Without giving me a time line, you are as bogus as those who predict stock market’s future performance.
I have enjoyed every one of my 41 previous cruises. I see no reason to experience anything different on tomorrow’s cruise on Mariner of the Seas ship. This ship has ice dancing shows on the large ice skating rink, and we are very fond of those. The best cruise for me was a 14 day journey from Southampton in UK stopping at Spain, Italy, Portugal, French Riviera, Monaco and Monte Carlo. Another memorable cruise was a 14 day journey from Hong Kong to Singapore, with stops in Vietnam and Thailand.
