"I was vaccinated and I was afraid of bleeding" "I stopped menstruating for more than 50 days"

I have seen many articles that some women who have been vaccinated against COVID-19 are complaining of abnormal reactions such as irregular menstruation and irregular bleeding.

Yesterday (31st), a post titled 'Please allow me to report female irregular bleeding as a side effect of the corona vaccine' was posted on the bulletin board of the Blue House National Petition.

The petitioner wrote, "Even though bleeding is the most terrifying thing for women, when they go to the hospital, they only get a prescription for a contraceptive pill or take Tylenol," the petitioner wrote. I did.

In fact, there are stories of experiences on the Internet that say that they experienced various side effects, from cases of irregular menstruation or a marked increase in menstrual volume after Pfizer vaccination, and testimonies that they did not menstruate for more than 50 days after vaccination with AstraZeneca.

Previously, overseas women testified that they had experienced adverse reactions from the early stage of vaccination.

However, the article reported that local doctors explained that side effects such as menstrual irregularities are not enough to worry about, and there is no reason not to get the vaccine.

There was also a lot of interest in the study results showing that Moderna's COVID-19 vaccine produces more than twice as many antibodies as the Pfizer vaccine using the same mRNA.

Bloomberg News reported that these results were confirmed in a study conducted on 2,500 people at a major general hospital in Belgium.

Among those studied, those who completed the Moderna vaccine had an average antibody retention of 2,881 units/ml, more than double the 1,108 units/ml in the Pfizer group.

The research team revealed that Moderna also had more 'active ingredients' than Pfizer, a key ingredient in vaccines that play a role in enhancing the body's immunity.

Moderna vaccine has a lower risk of breakthrough infection compared to Pfizer vaccine.

The Pfizer vaccine was found to be effective in preventing it from 95% initially to 84% after six months, the article said.
