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.

Understand @MarylouiseMcla1 but shouldn’t we be procuring the vaccines with the highest proven efficacy which at this point in time are Pfizer/ BioNtech and Moderna ones?

Hi Lucy. Indeed procuring higher efficacy is the better option.

What of those vulnerable groups with prior health conditions? With a vaccine that offers lower efficacy this group will be even more at risk through those who will believe covid is over. As many in Australia do already.

I believe the plan is for the vulnerable to be vaccinated early with Pfizer.

Thank you. I really trust your advice. I have severe asthma and I’m 65 so I’ve been worrying about the different vaccines.

You are likely to be considered medically vulnerable and get Pfizer.

So why does the best infectious disease doctor in the world Dr fauci say that is the Aim - He is very clear unsure what percentage but says it could be around 80 percent plus come on they just got the cheap one I am all for vaccinating our pop but we should have a choice

Higher efficacy is best option for sure. If you can still get asymptomatic infection after vaccination you can spread it. Herd immunity is only achieved when a vaccine prevents spread of infection (not just symptoms/death).

I disagree. Condemning me to 40% chance of getting Covid is a poor option.Getting even moderate or mild Covid can lead to complications- you have said as much yourself. Also I may not be able to get an mRNA vaccine in the future if I commit to AZ.

Higher efficacy is better for sure! But if thete’s no other option I’m suggesting any vaccine is better than none.
