But we need to remind ourselves that these treatments coming out are just that, immuno-treatments, not real and true vaccines.
What does this statement even mean?
What to Know About Coronavirus — COVID-19 Explained | Pfizer
What is Coronavirus? Coronaviruses are a large family of viruses that may cause respiratory illnesses in humans ranging from common colds to more severe conditions such as Severe Acute Respiratory Syndrome (SARS) and Middle Eastern Respiratory Syndrome (MERS).1

The Pfizer's vaccine under discussion is an mRNA vaccine that stimulates true immunity. Earlier in this thread, we were worried that it'd come in at too low of an efficacy, but now we know that its looking like ~90% efficiency after two shots (and ~80% efficiency with one shot). I think people may be bearish on the duration of immunity (Flu vaccines only offer 6-months of immunity). But COVID19 seems like it already offers 7+ months of immunity, so maybe its long lasting. (We'll find out as studies continue. The virus hasn't been with us very long yet...)
IIRC: its still not perfect. It looks like it takes 28-days before the vaccine takes effect. (So you could get vaccinated, but then infected 2-week later, before the immunity kicks in). But hot damn, 90% efficacy is really, really good news. You have to go far off into the pessimism-side before you can really come up with any negativity from today's announcement.
Especially this:
Based on current projections we expect to produce globally up to 50 million vaccine doses in 2020 and up to 1.3 billion doses in 2021.
