How do you feel about the fact that the trials did not use anyone that were not in good health?Just to be clear, you are talking about 2 vaccines there.
Pfizer co-developed one with German biotech firm BioNtech and will be the distributor for it.
Moderna developed the other one.
Assuming the phase 3 data holds up to what we have seen so far and there are no problems in early rollout, yes I will. I am technically high risk and definitely accept the science around vaccination. Vaccination definitely opens the door to at least breathing a little easier even if I still keep up best practices until I know the vaccination rate has reached a good level in this area.
Doesn't really affect me. I am in generally good health. My risk comes from being diabetic, but that is controlled.How do you feel about the fact that the trials did not use anyone that were not in good health?
The Moderna one doesn't need to be kept super cold it's a big advantage.Vaccines from both companies use messenger RNA vaccines. This is a new technology that has never been used in any vaccines before. It is the reason these vaccines have to be kept super cold with dry ice.....if they are kept warm for too long the RNA breaks down and would render the vaccine ineffective.
The vaccines consist of genetic instructions on how to make the modified spike protein from SARS-Covid-2, the coronavirus that causes Covid 19.
The genes are encoded in mRNA and packaged in lipid nanoparticles. Once the vaccine is injected into the body, human cells use the instructions to make copies of the spike protein for the immune system to learn to recognize.
These two types of vaccine produced by Moderna and Pfizer does not contain any virus or viral proteins, which means it can't cause a real infection.
There are some other teams around the world that are working on using live, weakened live viruses, dead or inactivated viruses, or live viruses, but not the Moderna or Pfizer ones.
They seem to be focusing on the elderly first.....the very group that hasn't responded well with the seasonal flu vaccine over the last 30 years, which is why it's dosage was increased. Of course this vaccine seems to be a "novel" kind of vaccine. (read the mRNA nanotechnology above) I suppose because it's the elderly affected the most so far they reason they should be first.It will be interesting to see how the government prioritizes distribution & administration of the vaccines.
Personally, it feels a little rushed to me - yes effectiveness has been demonstrated, but we don't know anything about longer term effects/safety - or even how long the immunity will last - it's just too soon to know any of this. So I probably won't push my way to the front of the line.
Moderna's is kept at -20C and Pfizers is -70CThe Moderna one doesn't need to be kept super cold it's a big advantage.
I think putting them in the very first group isn't a great idea unless we see they respond well in terms of immunity. Sure this is different than injecting proteins but their immune response still might not be great and the more vulnerable the worse it likely is. Those working in long term care homes being in the first group might give a greater effect when only able to vaccinate a small number soon to start.They seem to be focusing on the elderly first.....the very group that hasn't responded well with the seasonal flu vaccine over the last 30 years, which is why it's dosage was increased.

I'm with you about this whole thing feeling a little rushed! Trial periods are greatly reduced and emergency approvals would be needed.....
And -20C freezers are fairly common. -80C are rather heavy and we can't easily access those in large quantities. Most lab rooms I was in had multiple freeers whereas the department maybe had 10 -80 total. There's also the issue with the logistics of ensuring it's not being opened too many times. I can see that going well in areas where they are used to dealing with those sort of things. There's a lot of screwups in healthcare so getting this cross Canada I'm more skeptical in trusting having enough responsible people.Moderna's is kept at -20C and Pfizers is -70C
Moderna says it can survive for a month in a refrigerator and in a freezer at -20C for months.
Pfizer's can be kept in refrigerator for 5 days and needs to be kept at -70C for longer term storage, according to BioNtech's CEO.
I believe the health care workers will be included, BUT that order could change over time. It's probably a wait and see to know for sure.I think putting them in the very first group isn't a great idea unless we see they respond well in terms of immunity.

Long term care workers aren't always included with healthcare workers.I believe the health care workers will be included, BUT that order could change over time. It's probably a wait and see to know for sure.
Moderna's does sound better. I noticed Pfizer seemed to change it's affectiveness rate from 90% to 95% after Moderna announced there's was 94.5% effective. I suppose there's a race to lock in government contracts before the other.And -20C freezers are fairly common. -80C are rather heavy and we can't easily access those in large quantities.

Nope, that's only Pfizer. Moderna can be stored at -20 and in a fridge for up to a month per their release early this week. That gives them an edge for vaccinating the general populace. Pfizer might be better suited to hospitals where labs may actually have the necessary freezers.It is the reason these vaccines have to be kept super cold with dry ice.....if they are kept warm for too long the RNA breaks down and would render the vaccine ineffective.
I was broadly generalizing anyone that works in healthcare anywhere......well at least aiming for that.....Long term care workers aren't always included with healthcare workers.
I cocked my eyebrow at that, too, but I am sure they would say it is just additional data or something. There is supposed to be an independent review of the data as part of the FDA approval process so we will see what comes next.Moderna's does sound better.
