When will the vaccines have an impact on Covid 19
 

The Pfizer Covid 19 vaccine rollout begins tomorrow in the US. According to one of the developers of the Pfizer vaccine it will be next Summer before the world is back to pre Covid 19 normal. UGH!!! another year unless vaccinated or already have antibodies.

At least 30% percent of the world will have to be vaccinated to have an impact on the spread of the novel coronavirus pandemic, the biotech firm that developed one of the world's major vaccine candidates said Wednesday.

"But, we will only get a full effect if we reach about 60 to 70% of people," said Dr. Ugur Sahin, the CEO and co-founder of BioNTech said, adding that he expects this to be achieved by the end of next summer.

The question you asked is when will it have an impact and the answer is with the first dose given to the first patient. And more of an impact when the second person gets an initial dose. With each additional person who gets some protection we all get some protection. It is the accumulation of all these small incremental benefits that finally helps a community or a nation reach herd immunity. But it all starts with one person's inoculation which helps that person and everyone else.

...and this herd immunity is only for this incarnation of the virus. If the virus mutates, the vaccine might - or might not - protect anyone against the new mutation of it. We really won't know for sure until next year, whether or not it will mutate and require a new vaccine to protect against the mutation.

The vaccines are a fascinating, deep, and broad story with more questions than black and white answers. I find Pulitzer Prize winner Lori Garrett to be my "go-to" individual as a source of knowledge. She correctly predicted this Plague several years ago in her book. One question that comes up is the difficultly of delivery for the Pfizer and Moderna vaccines due to expensive refrigeration requirements. The JnJ vaccine is on schedule to be available sometime in January. It (I believe) has larger phase 3 volunteer numbers than the Pfizer vaccine - and other advantages. Garrett stated that Pfizer may be having trouble supplying the number of doses that they originally claimed - Moderna also because they are both based on the same system - requiring extreme cold storage - and needing the same raw materials in manufacturing. The JnJ vaccine uses a different approach so has several advantages. So, like I said - more questions than answers, which is to be expected with a completely new "novel" virus.

Am I the only one who hates that the news programs are constantly showing someone getting stuck with a needle?

I wish they would stop that.

As far as I am concerned, as soon as they start distributing it here, I'm going back to normal. I always wash my hands during the day, due to my travels overseas. I do not like to get physically close to people anyway so I always have social distanced. BUT, I have no intention of wearing a mask anywhere, unless it is mandated by a legitimate law. This is one step in the direction of giving us our freedom back.
Thanks to a great leader cutting the red tape and getting this pushed forward, we have a vaccine in months rather than years. The whole world is better for it, because the vaccine would not have been released anywhere else this fast either if not for the leadership here in the U.S. of A. Argue all you wish, but you know it's fact.

Why? Prime time TV shows much worse gore. A needle shot doesn't even produce any blood. Guess it doesn't bother me because I have given shots for years/decades and still do so.

For many, it will show benefits immediately, but for those that think it is a Hoax, mid summer should show a slow down in deaths for them through the herd immunity of the believers in science.

I find it extremely comforting to watch the injection process of a vaccine that will eventually give us back our normal lives.

The virus has already mutated hundreds of times. As a result of the vaccine, our antibodies will attack the virus spike proteins. The spike proteins are how the virus attaches to our cells to produce more virus. So the good news is that if there is a significant mutation to the spike protein, our antibodies may not recognize it, but it may also render the virus harmless. This is why there is optimism that the vaccine will staying power.

So, how many injections do I need to watch on TV to get immunity?

When I receive the Pfizer vaccine, when I finish getting both shots of the series and wait for the required length of time for my body to achieve immunity. Then the pandemic is over for me and mine. I can walk among the peoples of the world again, whether they have it or not.

I have already received shots for the seasonal flu and have been immunized against Herpes Zoster and Pneumonia (two kinds). I cannot get those diseases and give them to anyone.

If there were infants in our family I would be revaccinated for the childhood diseases, especially Pertussis, (whooping cough).

That is our feeling as well, we can burn our masks

That is what fast forward is for

Our position as well!
