Now, a report on my antibody titers.

Pfizer’s second session ended on June 21.

Two weeks later, on July 5, the results of a blood test for antibody titer (IgG antibody test)…

It was the strongest at 25,000 AU/ml.

* AU = Arbitrary Unit

As I wrote in the following blog, high titers (reference values) with and without antibody titers are…

4,160 AU/mL.

The actual FDA (U.S. Food and Drug Administration) standards…

It is defined as 840 AU/mL or higher, so the corona can be protected up to this value at a minimum.

Now, on August 25, less than two months after the first antibody test (50 days had passed), a second blood test was performed. The results…

That’s a dramatic drop to 6,216 AU/ml!

This is calculated to be 3/4 less.

This is consistent with the article below. In other words, it is not an outlier that occurred only in Fukuda, but rather a 75% decrease, rather than a half decrease, in about two months from the peak.

The usual estimate is that a third dose should be given by the end of the year. Of course, from reading various articles, I understand that two vaccinations will not cause serious illness. However, even if you get two shots, you can still get corona and transmit the disease. In other words, this is about all we can do as individuals, and now we have to wait and see if we can achieve collective immunity for society as a whole and the planet as a whole.

To this end, vaccination should be mandatory, not optional. At the same time, it will be necessary to take steps to ensure that people cannot enter restaurants, gyms, events, and other places where people gather without proof of vaccination.

New York City has announced that vaccinations will be mandatory for all indoor facility users beginning August 16.

By ensuring mass immunity, expanding medical facilities, and establishing a system in which vaccines can be administered easily, coronas will become like the flu.

Let’s all work hard to make this happen in the first half of 2022!
