You claimed PAP has screwed up the vaccination program because to date only <2% have received the COVID vaccine, yet offered us nothing in way of evidence that this rate is lower than most of the world. Instead all we have are two countries cited as example: US which together with China is one of the two powerhouses with the most vaccine R&D products and its super close ally Israel.
What is your definition for "fucked up" in terms of inoculation rate? Lower than median? There are 195 countries in the world, according to this tabulation of vaccination rate
https://ourworldindata.org/covid-vaccinations we are ranked around #47, placing us at around top 24%. Nothing to shout about for sure, but "fucked up"?
All these companies you have stated above have no COVID vaccine that is currently in the market, so I'm not sure why their presence here is evidence of the Singapore government having fucked up with not coming up with a vaccine. Also as you have yourself described above, these are all either manufacturing plants or RHQ support offices. They have no capability to develop a COVID vaccine anyway.
As for Singapore claiming to have a developed biomedical industry, I will admit there's some boasting from the government as we are certainly not as bleeding edge in the world of bio sciences as the PAP claims we are. But let's add some perspective here, currently the world of COVID vaccines is almost completely dominated by US and China. Even UK and Russia each have only one product. All are UNSC permanent members, so again there is nothing surprising that Singapore is unable to come up with its own COVID vaccine.
