As of Thursday, 43.5 percent of the country's population had received two doses.

As we enter the final days of August, 49% of eligible vaccine recipients (age 12+) have been fully vaccinated. Over 61% have received one shot.

As for the administration of a third vaccine shot already under consideration in response to reduced efficacy and breakthrough infection cases among fully vaccinated people, 

In Israel, they only count vaccines administered within the last 6 months.

So if you had your first shot in January and your second in February they will count you as unvaccinated because their research shows that the efficacy drops drastically after 6 months.

A steady regime of biannual boosters will be required.

We are suppose to get the second during the first week of August. I looked at the website from my Ward office. They are not scheduling any vaccinations in August. July is all booked. The late vaxxers will spill over into the other wards. The private clinics are booked all the way through August or no longer offering maybe due to no supply.

It might become a case of mix and match after August. It might be get it where you can, and you should not mind getting both Pfizer and Moderna.

I saw a segment on CNN that followed doctors of private clinics who private visits and are treating serious COVID patients and unvaccinated people at their homes. They are being refused by hospitals because they do not have anymore beds, or the hospitals just refused COVID patients because of the danger.

The patients are in bad shape and one Japanese guy had blue lips while talking to him. All of these patients are not being counting on the official numbers.

Theses are the people that police are finding passed away at home with no autopsy, but they have evidence of COVID without official testing.

Maybe I'm just ignorant but why is it so hard to get the shot and why do thousands of people need to que up in Shibuya?

Possibly yes to your first question.

Do you remember this reply to your last similar comment?

I am dumbfounded. In Itabashi, the vaccine info was sent out with a list of hospitals and clinics in the area offering the vaccine. Just call and make an appointment. Simple. I don't know why thousands of people need to line up in Shibuya

My reply was the following:

I have been pointing this out to those that keep saying this stuff.

Your ward/city, town, prefecture has nothing to do with how another place possible the ward right next to yours is doing.

Most of the Vaccination centres will not take outside their ward/city.

If they do, what times are available for appointments?

Notice the crowd, do they look like people that are not working?

As I said the weekend was going to be a mad house of those trying to get vaccinated, why? Because so many employers will not give time off to get vaccinated and even less time of if any side effects like fever occur in the following days.

Think if all the companies that refused to let their employees work from home insisting they travel everyday by train to work.

This applies to some of the big ones.

A close friend works as telephone customer service for a big telecom, contract through an outsourcing company, not telework, everyone have to go to the big telecom office daily, when she asked for time off to go for her vaccine the answer was NO she had to book a date far later and use vacation days, when she got a fever after her second dose, she was told to go into work anyway. ( Those saying No are the telecom giant's direct employees who manage the customer service centre not the the outsourcing company).

I know literally hundreds in similar situations including my sister in law, most of my adult Children's friends all basically recent or near recent university graduates.

So even if your ward/city has vaccine, even if they are vaccinating the younger age groups, unless they have tens of thousands of spots open on Saturday and Sunday, or open late night, most of these people cannot go or make an appointment

The solution to two problems is very simple.

Like AZ Moderna has been quite open to production in none Moderna owned facilities.

Japan has plenty of vaccine manufacturing capability and I doubt it would that long to adapt some to produce Moderna.

This eliminates the need to import and the possible contamination issues ( sorry but Spain isn't know for it's high attention to detail or high quality products).

Pfizer is a dead end, it refuses to outsource or license it vaccine so forget it.

So Pfizer is stupid coz the wanna secure their Quality and don’t wanna become a second Morderna?

Making a vaccine is not like making a Coke, its a complicated process that needs special hardware and well educated staff!

that's the true. No need to check the numbers. Most of the people won't even get tested because of troubles afterwards: work, kids school etc.

Situation is worse than presented. That's for sure. People dying alone, kodokushi, how many got covid tested? I think none of them. It's hard to say if they died "with covid" or "because of covid" slight difference but they are not doing covid test when autopsy. It's an old knews. (news year ago)

I am not able to get even first jab in city I live. Still, waiting.

Oh so you think Japan doesn't have the education or knowhow and isn't capable of securing the needed equipment!

You do realise that Japan has been producing it own vaccines for decades for just about everything.

Canada hasn't produced any vaccine locally in decades but has building from scratch a production facility for Moderna.

So I guess you think Japan and the Japanese are less capable than Canada or Spain.

Good luck with that idea.

So , where is the japanese Covid 19 vaccine?

I guess the concept of producing and developing being 2 different things is foreign to you.

As your example of Coke, they produce in many countries, using you logic, why aren't these countries producing their own developed version?

Plenty of products are developed in other countries then licensed for production in another!

Japanese encephalitis vaccine developed by a Japanese company has been produced firsts via licensing around the world.

This is often how vaccines and pharmaceuticals work.

Now you know.

New info coming out everyday. This may not be misinformation, but definitely lacking in information since most those in the hospital are probably over 75 years old, which makes this more like fear propaganda than information.

What makes no sense is your alluding that for some strange reason Japan wouldn't be capable of producing Moderna under a licensing agreement.

Studies up to now do suggest that combining vaccines gives better efficacy and durability.

But strangely the order of vaccines seems to matter a lot, with e.g. AZ+Pfizer being much better than Pfizer+AZ

This sounds like a perfect excuse to blame foreigners for the Japanese government's incompetent rollout of the vaccine program. They never had enough doses to vaccinate the majority of the population anyway. Then they mismanaged the supply they did have.

For example

0 ( +3 / -3 )

I grew up as a kid enjoying a "suicide mix" at restaurant soda fountains—mixing together various flavored sodas to create an original concoction that could be either incredibly delicious or nauseatingly revolting.

Mixing of vaccines, however, brings a whole new meaning to that term...

0 ( +3 / -3 )

Mixing the vaccines may be a good idea. When a vaccine is created, it is designed to create antibodies to certain epitopes (think 'shape and charge patterns) specific to a part of the target, that is, it creates a limited range of antibodies specific to just certain parts of, in this case, the 'old' COVID virus. Actual infection and recovery usually means a much broader range of antibodies has been elicited than would be seen with just a vaccine and, being broader, might also block the development of variants in the previously infected.

But, with just a narrow range vaccine blocking the 'old' form, new forms who vary out of the range of vaccine elicited antibodies such as the Delta strain are free to 'hang around' in the vaccinated or even infect them as we are now seeing in many doubly vaccinated individuals including creating severe enough infections to be fatal. "Breakthrough" is a disingenuous term meant to disguise the fact that the vaccine NO LONGER WORKS for that strain. It's a political obfuscation.

Another political obfuscation is that the 'unvaccinated' are somehow responsible for new variants. For unvaccinated people, the 'old' form is just as good as any variant to create infection and there is no 'selection' necessary for variants, no blocking of the 'old' forms allowing 'new' forms to become dominant. But, what we are seeing in the Delta is an accelerated rate of transmission and vaccinated people feeling free to again express their 'droplets' to the world are the 'carriers' and unvaccinated individuals their victims. Again, for unvaccinated individuals, the 'old' form is just as good for infection but what is now being transmitted is almost exclusively Delta, so, while the vaccines may be effective for the 'old' forms, they are facilitating the 'new' forms which are transmitted by the 'vaccinated'.

But, rather than admit that the old vaccines are failing and seeing their credibility sink even further, the Authorities are putting the blame on the virus naive rather than admit that the current vaccines will, at the rate we are seeing variation, soon become useless. This is not something that will be met with positive reactions by those who already doubt these Authorities nor by those who have previously trusted those Authorities.

Therefore, and with the hope that different vaccines may elicit somewhat different ranges of antibodies, mixing vaccines may increase the range of antibody recognition and be more effective than just the same vaccine given twice or even with a booster which, after all, is just more of the same. Regarding the 'fading' of protection, that is more likely the failure of the vaccine than such an uncharacteristic fading of 'immune memory' in such a short period. If immune memory were so labile, many of our other vaccines now providing long term protection for other diseases would show similar rapid 'fading'. Another obfuscation.

Our actual understanding of the Human immune system is still very primitive as evidenced by our inability to 'cure' even one of so many autoimmune diseases which afflict us, or even ameliorate without the agent used creating whole new issues. The best way to block transmission is a physical barrier to droplet expression which we call a 'mask'. We do not yet have any idea how 'variable' this virus may be nor if the CDC's current estimate of vaccine efficacy of 66% effective will sink even lower as time goes on. Probably, it will. Again, a vaccine 'cocktail' may have greater effectiveness of creating a range of antibodies broad enough to eliminate variants before they can become dominant.

But, no one really knows at this point what the future of this new visitor and parasite of our genepool will hold for us and anyone trying to 'predict' what will be next and convince us they 'know' will be lying. But, it's all part of the 'adventure', isn't it? So, mask up to protect yourself and to, perhaps, protect others from you, and the virus and its future kin will take care of those who don't. Life goes on, more or less, regardless, and even this rampant disease will not make a dent in Human hubris, our worst pandemic disease of all.

without any specific data to go off the government is in a difficult position here. if only there were some way to invite a select group of people to a clinic and have them all try mixing and matching. they could call it something like a 'clinic try all' because all the people at the clinic get to try it.

This is something the German health authorities started recommending a while ago. Others disagree. Fact is, everybody is fumbling, and while this cocktail idea might have some benefits, it also might have risks.

It was made in Germany under following circumstances:

Astrazenca was not recommended anymore after investigation by german Government for people under 60 !

So person who already got first jab with Astrazenca and waited for second jab got finally the Pfizer vaccine. This was ok.

It was never the plan in Germany like in Japan now to mix vaccine for reason of supply shortage!

These vaccines are not working! Look at what's happening in Israel. It's obvious that this isn't about health.

Huge reduction of hospitalizations and deaths? high-risk population now in comparable terms with the unvaccinated low-risk? this proves the opposite of what you say it would.

And once again, health experts saying this is an important problem while you saying the opposite based on absolutely no evidence is not exactly a very difficult choice.

A UK study has shown that the AZ vaccine followed by the Pfizer one actually gives a better T-cell response than either vaccine on its own. (This doesn't work if you give the vaccines the other way round though, so be sure to get the order right!).

Me, too and many others for sure as well. Japan should return the entire delivery to the importer/producer and insist on replacement. Contaminated vaccine is a clear NO!

We will see when Japan is ready to produce its own vaccine or at least producing vaccine in Japan on licence.

Easier to control than to import it.

So once you get vaccinated, you have to receive a booster shot every six months until the COVID-19 pandemic is over or for the rest of your life.

The rest of your life .. htmmm.. You make "the rest of your life" sounds like a really long time. Now, with the Delta mutation and hospitals rejecting admissions, if you are unlucky and get exposed to a lot of of the virus , young or old, the rest of your life might be just 2 weeks.
