What is the importance of maternal health care during pregnancy? – Not connected

However, there is no research to suggest that the COVID-19 vaccine can build up in the ovaries with a risk of infertility. BBC News says the misunderstanding on the issue stems from a misreading of animal studies provided by Pfizer, the manufacturer of one of its mRNA vaccines.

Rats received a dose higher than humans (1.3 times). However, these experiments showed that only 0.1 percent. The total dose of the vaccine is excreted in the ovaries of female rodents within 48 hours. The greatest amount of this preparation is found at the site of its administration, ie in the upper arm. After an hour, the rate was 53 percent. From this scale, and after 48 hours – 25 percent. The next place with the largest amount of it was the liver, with 16% of it detected after 48 hours. The vaccine you received. This is not surprising because the liver helps remove waste products from the blood. The same is true for drugs and many other substances.

There is a slight increase in fat in the ovaries

Ovarian lipid levels increase slightly after administration of the mRNA vaccine into the ovaries within 48 hours. This may be because the mRNA that stimulates the body’s immune response is delivered in a lipid envelope (so that it is not attacked by immune cells and is destroyed before they release immunity to COVID-19). However, there is no evidence that the mRNA itself, that is, part of the genetic material of the virus that codes for only one protein, penetrates into the ovaries (after being produced in the body, an immune reaction occurs).

There is also no indication that the COVID-19 vaccine may cause a miscarriage in pregnant women. BBC News acknowledges that such suspicions have been reported to the British authorities who are dealing with the side effects of the medicines. However, this does not mean that there is a causal relationship between the two.

The number of miscarriages did not increase

Official data shows that pregnant women who have been vaccinated against COVID-19 have the same number of miscarriages as the general population, i.e. 12.5%. In mid-June 2021, he wrote about this in the “New England Journal of Medicine” in the article “Preliminary results of the safety of a Covid-19 mRNA vaccine in pregnant women.” It concluded that there are no concerns as yet about the safety of mRNA vaccines in pregnant women.

Monitoring of side effects in the UK and many other countries is very reliable. In this way, it was discovered that the targeted AstraZeneki vaccine rarely increases the risk of developing blood clots in women.

There is no indication that the COVID-19 vaccine may trigger an immune response against the fetus’s placenta. These suspicions were put forward by Michael Yidon, and were supposed to stem from the fact that the coronavirus protein encoded by the mRNA was supposed to be similar to isyncitin-1, a protein used in the placenta. The immune system will also attack the placenta cells by producing coronavirus antibodies.

However, this contradicts the research conducted by the American specialist Dr. Randy Morris. He studied patients undergoing in vitro IVF procedures. The observations included 143 women, some of whom had been vaccinated against COVID-19 or had previously contracted the disease. All of them were similarly pregnant and gave birth.

Those who say the vaccine increases the risk of miscarriage don’t explain why this doesn’t happen for women who recover and then become pregnant. What is the difference between the antibodies against SARS-0CoV-2 caused by the infection and those produced by the vaccine? asks Dr. Randy Morris.

The US Centers for Disease Control and Prevention (CDC) issued a recommendation several days ago that pregnant women should be vaccinated against COVID-19. There are no contraindications for this in previous or recent studies – they are mentioned in the justification for the decision. However, it has been observed that in case of infection with SARS-CoV-2 during pregnancy, the risk of severe COVID-19 infection, premature birth and even miscarriage is greater.
