Its not about the number of nurses you wanna source, the problem is PEOPLE just dun wanna vaccinated for whatever selfish reasons.
Even you have improved version there are still many iron teeth froggies. Last time beach whine … wanna Fatty Xi's vaccine … now give them and STILL MANY dun wanna jab

I think is fear, they may want even safer ones, if so it is not wrong to me. 
Why label they as selfish then? You insist only unvaccinated spreading is without proof at all.
And is open secret vaccine is for emergency used only. 
not even lesser side effects mature technologies vaccine can sway remaining their mind.
 
Despite threat of job, medical cost, leisure  threats. I observe 87% vaccination rate has been a while. 

Have more nurses now is to allow existing nurses to rest, without sufficient rest, their immune system will be weaken,
even vaccine cannot help. 
Also more nurses are required for ageing Sg. 
Nothing wrong.
