Covid Vaccinations Have Not Been Connected To Pregnancy Loss

The following is a synopsis of some recent COVID-19 studies. They include research that requires additional study to corroborate the findings and has not yet been certified by peer review.

Two new studies published in peer-reviewed medical publications add to the evidence that COVID-19 vaccinations are safe before and throughout pregnancy.

Covid Vaccinations Have Not Been Connected To Pregnancy Loss

One research, published on Wednesday in The New England Journal of Medicine, followed about 18,500 pregnant women in Norway, including around 4,500 who miscarried.

Researchers discovered no relationship between COVID-19 immunizations and the risk of miscarriage in the first trimester, regardless of whether the vaccines were manufactured by Moderna, Pfizer, and BioNTech, or AstraZeneca.

According to the researchers’ estimations, women who had miscarriages were 9 percent less likely to have been vaccinated overall. In a separate study published on Thursday in The Lancet, researchers followed 107 women who fell pregnant while taking part in AstraZeneca’s vaccination trials in the United Kingdom, Brazil, and South Africa. Seventy-two of the women were given the vaccination, while the rest were given a placebo. According to the researchers, AstraZeneca’s vaccination did not influence the chances of successfully bringing the pregnancy to term.

Pregnant women should be vaccinated since they are at a higher risk of hospitalizations and COVID-19 problems, and their newborns are at a higher risk of being born prematurely, according to the authors of Norwegian research. Furthermore, immunization during pregnancy is likely to protect the newborn child from COVID-19 infection in the first few months following delivery.

In recent research, healthcare professionals in France who received the first injection of AstraZeneca’s COVID-19 vaccine and then the Pfizer/BioNTech vaccine for their second shot had better immune responses than those who received two shots of the Pfizer vaccine. 

Combining multiple technologies has been shown to increase immune responses to other viruses, and the present work implies that this may also be true for the coronavirus. Both vaccinations in the research send instructions to cells in the body that direct them to produce a fragment of the protein that resembles the spike on the coronavirus and stimulates an immune response. They do it, however, in quite different ways.

According to Vincent Legros of the Universite de Lyon in France, writer of research published on Thursday in Nature, both regimens provided safe and efficient protection. However, combining the AstraZeneca shot with the Pfizer/BioNTech vaccination provided even higher protection than two doses of the Pfizer shot, including protection against the Delta form, according to Legros. 

Researchers discovered that a “significant proportion” of middle-aged COVID-19 survivors with no prior dementia experienced cognitive impairments more than six months following diagnosis. They examined 740 participants ranging in age from 38 to 59. Approximately half were white, and 63% were female. 

On assessments of cognitive skills, 20% had difficulty converting short-term memories to long-term memories, 18% had difficulty processing information quickly, and 16% had difficulty with skills required for planning, focusing attention, remembering instructions, and juggling many activities.
