Land of the Missing Dose?

Japan may have to waste millions of the 144m shots of the Pfizer/BioNTech Covid-19 vaccine it purchased (https://www.theguardian.com/world/2021/feb/10/japan-pfizer-vaccine-doses-wrong-syringes). The vaccine wastage will occur, because the country has a shortage of low dead space disposable syringes. Vials of the vaccine, contain 6 doses but only five can be extracted, using standard syringes. The vaccine deteriorates quickly on reaching room temperature. A number of other countries are also suddenly realising they also need low dead space syringes (so, competition for them could be fierce). It is also a little worrying that Japan's mass vaccination programme will only start on 17th February, with inoculations for 10-20,000 frontline health workers. This cohort will be carefully monitored, before treating another 3.7m health workers in mid-March. Vaccinations of the 65 and over group (along with people with underlying health conditions), won't start until early April. Japan will then get round to treating young folk, about the time of the rescheduled Olympic Games in July! This drawn out process leaves plenty of scope for viral mutations (we could have an Olympic variant?). I wonder also how the country will minimise the importing of Covid-19 variants at the time of the Olympics (July seems a bit early for an event involving people from most parts of the globe).
