It is, the the fault isn't entirely on the tourists (specially if they're respecting and give two fucks about the places they're visiting); the governments have been pushing tons of pro-tourism stuff everywhere for years, hence why we grew that industry so much, often without thinking of long term consequences and economic balance. So now, we have an economy overly dependent on tourism (with all the good but mostly bad stuff that brings), which, in addition to other shitty decisions like massive roadway investment instead of railway (we have one of the best road network in Europe, but a shitty railway one, significantly shrinked down in the last 40 years), have led to lots of serious issues preventing good development of a lot of other industry we could have and once had. The classic example is Algarve (the southernmost region) is so dependent on tourist they had a very hard time during COVID. Outside of Lisbon's (<2M) and Porto's (>1M) metro areas, every other city has less than 500k people, and the vast majority less than 100k, which presents obvious issues.
Anyway, sorry for the shit dump ๐
Was going to say that too. Regardless of the motives and driving forces behind the incredible speed at which the vaccines were developed (i.e. certainly a similar urgency could be applied to other diseases killing thousands and millions in poorer countries, but there ain't as much interest in that), the mRNA technology proved quite powerful and an avenue to continue exploring in future research.
