Revenue Boosters, yo
You mean like the flu shot that has been offered annually for decades?
Completely expected it myself. If you're surprised, you're just naive in my book. Nobody vaccinated for last year's flu is considered vaccinated, ever.
Well, I am a weird answer. Yes and no. I am an American. But for two years I didn't leave Portugal. That said, I've been back in the US for the past 6 weeks now.
In Portugal they're completely set up for tests. Even the sidewalk testing labs will give you an electronic turnaround result within 1-3 hours, sometimes even in minutes. Better still: if you're a Portuguese resident or citizen, it's free.
In the U.S., I'm not entirely sure. I've heard others with lots of headaches trying to find a place that could do 72, let alone 48-hour. turnarounds as some nations require. Worst case scenario you have to pay through the rectum at an airport or nearby one.
All it takes is a summer with British tourists vomiting in your streets to know that vaccines are no match for the British will towards self-destruction.
