This article is encouraging, and I think I understand how the virus becoming endemic is essentially/eventually a good thing: it is when no one has immunity that it is the most problematic.
We are here on an island that has had very little infection compared to the rest of the planet, so I guess we will fall behind in this effect? In most places, people will build immunity because they get infected (herd immunity?) and the vaccinations will help ensure you either have immunity ready so you the infection is much more manageable when you do get sick.
Vaccines will be administered to 12-18 year olds starting next month (Pfizer willing). If there are no plans to vaccinate children below 12 anytime soon, should I think waiting 2 years before my 10 year old can travel?
