So, I think it's great that they're looking at this, and I even believe that on balance it is probably the best bet to go ahead with this idea in countries that have a vaccine shortage. However, I just have to point out: "Levels of both antibodies and T cells were comparable to those found in people who have recovered from COVID-19." I can think of another reason this might be true. Maybe, you know, most of these people actually got covid-19, in the months after their quarter-strength vaccination. Now, this might still indicate that it helped them out, since they apparently were asymptomatic or at least did not have a serious enough case to attract the attention of the researchers, but it would not help stop the spread of the virus. So, the idea that there is no downside or risk to going with the quarter-dose, is not necessarily true. It could be that a quarter-dose leaves you just as likely to get (and perhaps spread) the virus, although it does prevent death or serious hospitalization. Again, I think on balance it's worth the risk, given the situation many countries are in, but I just think it should be acknowledged that it is still a risk.
