Here I offer answers to three questions regarding the effects of the vaccine! Q1. Will the vaccine work on the stronger strains as they emerge? Q2. When does the body start to make antibodies after the vaccination? Q3. How long are the vaccines effective for?
Now for the answers of these three questions on the effects of the vaccine!
(The following article was made using information based from doctors, but also contains some assumptions made by me, so please use this article as less serious read)
Q1. Will the vaccine work on the stronger strains as they emerge?
mRNA vaccines work against new mutant strains, so the vaccine should work against any newly emerging strains.
First, some background information. There are two types of vaccines (mRNA and adenovirus).
Pfizer/Moderna are mRNA vaccines
Astrazeneca/Johnson and Johnson are adenovirus vaccines
mRNA also work against the strains that are currently present. (Based on experience, not epidemiological surveys.)
Many in Europe have taken Astrazeneca, but Pfizer is more resistant to mutant strains. Clinical studies testing if getting two shots of the mRNA vaccines work on the mutant strains (delta, epsilon, kappa), mRNA vaccines work because cellular immunity is retained if antibody titer is decreased. Severe symptoms are being successfully prevented in cases of mutant strain infection after two shots.
The coronavirus, much like the flu, is something we will be living with forever; society will begin to treat it like the flu as we deal with it moving forward.
An mRNA (messenger RNA) vaccine is a type of vaccine that uses blueprints to identify the criminal’s (virus’) face, and has the police capture them immediately.
Neutralizing antibodies were produced in more than 90% of those vaccinated with two doses, including for the mutant strain. Yokohama City University confirms the effectiveness of the vaccine.
After vaccination against the novel coronavirus (mRNA vaccine), the germinal center of the lymph nodes remained active 15 weeks after vaccination, and there is a high chance that most of those who have received two mRNA vaccinations will not require additional vaccination.

“Cocktail vaccinations with adenovirus and mRNA vaccines also recommended. / Strong recommendation to alternate between different coronavirus vaccines, Germany.”
Q2. When does the body start to make antibodies after the vaccination?
They are typically generated between two to four weeks after your second vaccination.
If you want to know how many antibodies you have, you can do an IgG antibody test (anti-S protein antibodies = blood test to see if antibodies have been produced). It tests your blood to measure the antibody titer in the blood and determine whether it is negative or positive. *S = spike
In the U.S., patients who had low antibody titers received three doses of the vaccine. (The U.S. does not use coupons)
The reason for the strong adverse reactions and fever is that the Pfizer and Moderna are mRNA vaccines (which react to PEG = polyethylene glycol). PEG is found in many medical products such as cosmetics, tablet coatings, ultrasound jellies, and ointments. Repeated contact with PEG causes antibodies to form against it; the body reacts violently when large amounts of PEG are introduced into the body through vaccines. That’s why the second vaccine is harsher.
There is some debate as to whether or not there is a relationship between this adverse reaction and the effectiveness of the vaccine, but it is impossible to tell without an Iig antibody test to determine the amount of antibodies formed. Four weeks after the second vaccination, you should go to a clinic that specializes in such tests for a blood test (¥11,000 , ¥3,000 for a certificate). If you have an insufficient amount of antibodies, or if you remain negative, you should have a third round of vaccination. Testing your saliva with a cheap early PCR test kits after acquiring antibodies may still result in negative results. Saliva tests are not reliable.

Three Pzifer vaccines increases antibodies by 5-10 times
Q3. How long are the vaccines effective for?
The antibody titer reduced by half over six months. But you still have 1,000 antibodies where, for example, 50 would be sufficient.
Even if you lose half of 1,000 in six months, you still have 500. Another six months brings you to 250; another six months, to 125; another six months, to 62, and so on. Which means that you will be fine for two and a half years.
Chief Cabinet Secretary Kato said vaccines won’t remain effective for even a year, but he may not have had any basis for this statement.
We have learned that, while antibodies may appear to drop in number, they remain stored in the body’s memory, and if stimulated in any way, the body produces antibodies within a week.
Therefore, those who have been vaccinated may be safe for a longer period than expected.
We may see a method to measure the body’s memory of the vaccine developed in the future.
…So let’s all get out and get our vaccinations!
