> The urgency that prevailed in 2020 has evaporated. I know parents of young children who are extremely disappointed that it took less than a year to trial and approve the first COVID-19 vaccine for adults, and then a full year and a half to trial and approve the first COVID-19 vaccine for children under 5.
Even the approved one that exists today barely does anything. There were a ton of attempts before that that simply straight out didn't work.
