Herd immunity is not the goal of current vaccines because 1) all levels infections not preventable 2) would need high efficacy for all level of infection & high pop coverage. Please get any vaccine to give better chance of protection from symptoms, possibly severe COVID & death.

Great news frontline staff will now be tested daily. Now we need to reduce risk of incoming COVID19 & variants with testing international travellers & crew before they board & immediately on arrival.
My colleagues and I wrote 7 Dec an open letter to State/Fed asking for rapid antigen testing of every incoming travellers without exception. Better late than never.

Vaccine rollout requires precision planning and 1000s of staff. To keep this important program on track multiple protection barriers for quarantine and travellers must be in place and foolproof.

Touching the mask is a risk in healthcare settings, while no evidence in the community setting. Behaviour is the key yes but to make mask use the new 'norm' when case numbers rise making it mandatory is the first step, along with giving them out freely.

Mandatory masks will help to prevent the spread of COVID 👌. Government, shopping malls and venues should hand out free masks to augment the current physical distancing and hand hygiene stations. Assisting everyone's cooperation is more effective than fines.

Mandatory mask use protects everyone & is essential during outbreaks. Why can't we "safely speed" on roads? If we get it wrong we kill ourselves as well as others. Why can't we 'decide' when we wear a mask ? Because if we get it wrong we infect ourselves but also others.

Im not suggesting we cant do this. Rather at this rate of injecting (& Pfizer instructions require additional staff) health services needs to focus on just mass vaccination not chasing cases. UK has achieved 138,000 and 15mins per person (for older residents?) we must focus staff

mass vacc will use no gloves, require hand hygiene between patients, Pfizer requires informed consent, check no contraindications, drawing up .3mls & quality check of solution before inject, review each person after injections. UK factors 15mins. Faster just needs more staff

no so its assumed everyone (without contraindications) should be tested as immunity from natural infection may last 8months or even less.

vaccines don't ringfence until it reaches herd immunity because vaccines dont (yet) stop symptom fess infection and transmission by vaccinated persons). Herd immunity for COVID is yet undetermined but assumed to be greater than 80%.

I'm not suggesting we cant do this. You misinterpret my tweet. We need all hands on deck - not chasing cases.

There is a weekly surveillance report that gives within 24, 48 and 72hr of tests reported but tricky to find (I just looked and couldnt find it). Ask NSW because your questions are important.
