Is Vaccine the Cause of the Increase in Syphilis? ｜Two Hypotheses

Know the characteristics of syphilis first before chasing conspiracy theories.

Syphilis infects with or without immunity.

Since the beginning of 2022, the number of patients diagnosed with syphilis has increased rapidly in Japan.

It is said that it exceeds the average year in half a year.

``Syphilis'' worst pace, 5,600 people in half a year ... Expert ``conspicuous sexual intercourse with unspecified majority through SNS'' | Yomi Doctor (Yomiuri Shimbun) (yomiuri.co.jp)

According to the above article, the director of the private care clinic Tokyo said, "I don't know the exact reason," but "people who had sex with an unspecified number of people they met through SNS," and "users and workers of sex services." It is said that there is an increasing trend in.

However, it seems that some people who suspect that the common sense of the world and the "normal" for experts have a backside, and that this is because they were vaccinated against the coronavirus.

Because of the vaccine, the immunity weakened, making it easier to get syphilis.

But think about it.

You can get syphilis with or without immunity.

If there is contact such as sexual intercourse.

The proof is that the corona vaccine is not a roundabout way, but it is an infectious disease that will recur even if you get syphilis once and acquire immunity specialized for syphilis.

So, if immunity is lowered, there will be many other epidemics, and I think it will be difficult to collect data on syphilis and connect it to a vaccine.

The number of reports of syphilis has been increasing in recent years.

Looking at the data from 2010, it only dropped in 2019 and 2020, and the rest is on the rise.

If vaccines are the reason, what vaccines are responsible for the rise since 2010?

At that time, there shouldn't be a corona vaccine yet.

Two Possible Hypotheses

My personal opinion is that the increase in syphilis is due to the decline in its prevention.

The best way to prevent syphilis is to get tested and treated before you pass it on to others and to use a condom during sexual intercourse.

Self-restraint is being called for in the corona wreck, but in the midst of it, there are people who act on sexual intercourse, which is the height of close contact.

Are they properly diagnosed and treated?

Are they wearing a condom?

Looking at various questionnaires, it seems that the reason for not wearing a condom is summarized as "because it feels better without it".

It is an action that prioritizes immediate pleasure and does not think about the future, such as pregnancy, abortion, and human relationships.

It's human instinct, so it can't be blamed unconditionally, but it's certainly an act that lacks caution.

It is a hypothesis that it is possible that the balance between cautious and active people is broken in the corona crisis.

Another is the spread of contraceptive methods other than condoms.

The low-dose pill and after-pill seem to be gaining popularity in recent years due to the reliability of the contraceptive method.

The pill may be an excellent contraceptive method, but it is vulnerable to infection prevention.

If the other person has not been tested or treated for a sexually transmitted disease, you may still need a way to prevent direct contact, such as a condom.

And I would like to pay attention to the fact that the spread of SNS, which the expert said at the beginning, is promoting an environment in which an unspecified number of people can have sexual intercourse.
