died 2 days after being vaccinated against coronavirus

A 63-year-old man died just two days after receiving a dose of one of the coronavirus vaccines. This happened in Hong Kong, the health ministry said in a statement.

What is not yet clear is whether there is a direct relationship between his death and the injection against him. coronavirus.

According to estimates, the person died just two days after receiving a dose of the China Sinovac vaccine on February 26. The health department said the man developed severe breathing difficulties and died on February 28.

Although it was not stated in the statement which vaccine the person received, the health department said it had contacted hospital authorities for more information and an assessment.

The health authorities worldwide are satisfied with the rapid development of vaccines against Covid-19, which are considered safe and effective. However, people with serious underlying health conditions have been advised to seek medical attention first.

They found a new coronavirus mutation in a baby in Sweden

Covid-19 mutation detected after the birth of a baby

A team of researchers from Lund University in Sweden has identified a new coronavirus mutation in the body of a baby newborn after being infected in the mother’s womb.

The new variant was named A107G and was detected days after specialists at Skåne Hospital performed an emergency Caesarean section on the woman, who was suffering from severe abdominal pain, by detecting that the fetus had a heart rate. low. Then they took swabs from the mother’s and baby’s throats, confirming that both suffered from covid-19.

Analysis of the genome of the virus showed that the newborn baby was infected while in the womb. Initially, research indicated that mother and newborn had identical viruses. However, a subsequent genetic test showed that the virus in the newborn’s body had mutated with the original strain passed on from the mother.

This is the first case of a genetic change in the coronavirus when transmission has occurred from mother to fetus before birthsaid Mehreen Zaigham, postdoctoral researcher in obstetrics and gynecology at Lund University

Scientists hypothesize that the genetic changes in the virus may have been caused by the baby’s contact with the external environment outside the womb.

Likewise, the researchers were able to establish that there was significant inflammation of the placenta, as half of its tissues were damaged. Additionally, the coronavirus protein has been found on both sides of the placenta and in all areas affected by the abnormality.

As the woman recovered from the illness, the baby required additional medical attention due to her premature birth. Regarding the mutation, the child’s immune system could neutralize the virus and accumulate antibodies.

Covid-19 can be transmitted during pregnancy

In July last year, a study in France, conducted by the journal Nature, pointed out that it is possible for babies to be infected with the coronavirus while they are still inside their mother’s body.

The case was analyzed on the basis of a fact reported by a pregnant woman 23, who was admitted to a French hospital with a persistent cough and diagnosed with Covid-19.

Three days after entering the hospital, the young woman gave birth to her son by cesarean section. The baby underwent the corresponding tests for the virus called covid-19 on the same day of his birth and they were repeated 18 days later, and in both cases the results obtained were positive.

Although previous studies have highlighted the possibility of mother-to-child transmission through the placenta, this is the first case to be verified in a real way since the pandemic threatened the world.

“We demonstrate the transplacental transmission of SARS-CoV-2 (the virus that causes covid-19) in a baby born to an infected mother and with a neurological disorder,” says the report of the investigation, which was conducted by Dr Daniele de Luca, from the Antoine Beclere hospital in Clamart.
