FDA and CDC announced the resumption of Johnson & Johnson novel coronavirus vaccine, but young women under the age of 50 should pay attention to it

The U.S

.

Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) said in a joint statement on April 23 that they would cancel the previous proposal to suspend the use of Johnson & Johnson’s novel coronavirus vaccine and immediately resume the use of the vaccine

.

Ten days ago, in view of the fact that six people in the United States reported severe thrombosis and thrombocytopenia after being vaccinated with Johnson & Johnson novel coronavirus vaccine, the United States health agency suggested suspending the vaccination of the vaccine

.

The statement said the United States should resume the use of the new coronavirus vaccine developed by Johnson & Johnson

.

FDA and CDC believe that this vaccine is safe and effective in preventing coronavirus infection

.

The FDA has determined that the known and potential benefits of vaccines outweigh the risks in people aged 18 and older

.

According to the associated press, the FDA also said on the same day that the United States will fully resume the vaccination of J & J novel coronavirus vaccine on the 24th

.

The FDA and CDC will remain vigilant and continue to investigate the risk, the statement said

.

According to the in-depth analysis of the syndrome report, Johnson & Johnson’s new coronal vaccine may be associated with severe thrombosis and thrombocytopenia, but only a very small number of vaccinators will have this syndrome, CDC director wallensky said on the same day

.

The statement pointed out that vaccination institutions and individuals should check the “information sheet of Xinguan vaccine” before vaccination to learn about the potential risks of fatal syndrome such as severe thrombosis and thrombocytopenia

.

Johnson & Johnson Xinguan vaccine was developed by Yang Sheng pharmaceutical, a subsidiary of Johnson & Johnson, and was authorized by FDA for emergency use at the end of February this year

.

According to the latest statistics of the CDC, as of April 23, nearly 8 million people in the United States had been vaccinated with Johnson & Johnson vaccine

.

A total of 15 people (including 6 previously reported) had the above syndrome, including 3 deaths, 7 hospitalizations and 5 rehabilitation

.

All of the 15 were women, most of them under the age of 50

.

They developed severe headache, abdominal pain, nausea and other symptoms 6 to 13 days after the vaccination

.

CDC independent Advisory Committee on immune practice held a meeting on the 23rd to discuss the latest data of related syndrome reports and conduct risk benefit analysis

.

On the same day, the committee voted 10 in favor and 4 against, supporting the resumption of the vaccination of people aged 18 and above

.

The chairman of the committee, Arkansas health secretary Jose Romero, said after the vote that members of the committee agreed to resume the use of J & J novel coronavirus vaccine

.

“Our difference lies in how to convey the vaccination risk to the public.”

.

Remind women under the age of 50 to pay attention, according to the proportion, the probability of vaccination and thrombosis is less than two parts per million

.

Compared with infection caused by non vaccination, it is obvious that the benefits of vaccination outweigh the risks

.

However, when the first expert group voted on Johnson & Johnson vaccine, there was no negative vote

.

This time, there were four negative votes, which also proved that four experts were still worried about the risks of Johnson & Johnson vaccine

.

For the majority of thrombosis are women under 50 years old, the expert group suggested that this part of the vaccination population should be given warning

.

Johnson & Johnson said it supports putting warning labels on vaccines

.

At present, among the 8 million people who have been vaccinated, 15 have developed thrombosis, among which 3 have died and 7 are still in hospital

.

The latest death occurred in Oregon, where a woman in her 50s died two weeks after being vaccinated

.

It is understood that this woman has a rare and serious thrombosis, platelet content is very low

.

The Oregon Department of Health said: “until the investigation is completed, it cannot be determined whether her death is related to the vaccine.” According to the CDC’s analysis of rare thrombus data, all the 15 patients with thrombus were female, 13 were under 50 years old, and 2 were over 50 years old

.

Twelve of them developed a very dangerous and rare cerebral thrombosis, which is called cerebral venous sinus thrombosis (CVST)

.

If there is no timely medical assistance, it will easily lead to death in a short time

.

As a result, CDC experts have been looking for more research

.

However, at present, it is obvious that there is no connection between vaccine and thrombosis

.

It is only based on the data such as the proportion of thrombosis and gender

.

Europe has taken the lead in resuming J & J vaccination

.

The European Drug Administration said on the 20th that the benefits of using J & J vaccine outweigh its risks, and suggested labeling the vaccine with a warning of potential risks, Reuters reported

.

CDC experts say that this kind of thrombus problem is very common

.

COVID-19 also causes thrombosis

.

Daily drugs such as contraceptives may also cause thrombosis

.

White House COVID-19 consultant Jeff Zintes (JeffZients) said that the US states had mastered 9 million doses of Johnson’s vaccine and could be used soon if it was resumed
