Boosting Pfizer’s Covid vaccine in five- to 11-year-olds led to a 36-fold increase in antibodies –

The injection manufacturer said today that Pfizer’s third dose of COVID-19 vaccine for children ages five to 11 increases anti-Omicron antibody levels by 36 times.

The New York-based pharmaceutical giant said the results were “boosting” by providing children with additional vaccines to “maintain” protection against the virus.

But the Food and Drug Administration (FDA), the vaccine regulatory authority in the United States, has warned that it does not approve additional injections for the age group until more people are fully vaccinated.

America may be one of the first countries in the world to approve Covid boosters in more than 5 years, behind Italy, which approved it for the age group in December.

The Pfizer vaccine is the only first and second dose approved for use in children aged five to 11 years in the United States. The Moderna and Janssen vaccines, which are also used for vaccination, are only approved for people over the age of 18.

Pfizer announced today that the third dose of its Covid vaccine has increased anti-Omicron antibody levels in children aged five to 11 years by 36 times. US drug regulators have not yet approved the third dose of Covid vaccine for this age group.

In clinical studies, 130 children aged five to 11 years received a third dose approximately six months after the second injection.

A month later, 30 of this group had their blood serum tested for antibodies to the virus.

Pfizer reported that levels of anti-micron antibodies increased 36-fold during this period, while those against the original Covid strain increased six-fold.

Children are at negligible risk from Covid, with official statistics showing that 980 deaths in the age group have been caused by the virus since the start of the pandemic.

By comparison, 252,928 of the 85+ people most at risk for the virus have Covid patients or 258 times more people on their death certificates.

Vaccination coverage for youth under 11 is patchy: only 30 percent are fully vaccinated. Only half of the children over the age of 12 received three doses.

The FDA has approved the third dose of Covid vaccine for immunocompromised children ages 5 to 11.

Pfizer tested the age group Covid vaccine during Phase 2/3 clinical trials.

He used a booster dose of 10 micrograms (ug), which is about one-third the adult dose. This is the same amount used in the first and second doses for children.

In response to the findings, Pfizer said it will now seek emergency use authorization for the booster in the US and European age group.

The study did not examine the effectiveness of the third dose in preventing Covid transmission to children under 11 years of age.

It was unclear whether the study participants had previously recovered from Covid.

It was also unclear against which strain of Omicron the antibodies were tested.

Italy is one of the few countries in the world that currently offers boosters to children aged five to eleven.

An article in February suggested that two doses of the vaccine were only 12 percent effective against Omicron infection in children under 11.

Researchers from the New York State Department of Health followed 360,000 children ages five to 11 who received two doses of Pfizer vaccine at the height of the Omicron wave.

They found that the vaccine’s efficacy against infection with the superinfectious variant dropped from 67 percent to 11 percent within 34 days of receiving the second dose.

But for the 500,000 youth aged 12 to 17 followed in the study, the decline was 66 to 51 percent over the same period.

Parents can vaccinate their children with the double vaccine to protect them from Covid.

But concerns have been raised about the rare side effect of heart inflammation that goes away after an injection, which is more likely in men.

Scientists say that most cases go away on their own without any problems.

Pfizer’s profits soared as it took advantage of the Covid blow during the pandemic. Johnson & Johnson still has the highest turnover.

A to work Last October it also found that about half of pediatric Covid cases were asymptomatic, which was before the milder variant of Omicron became dominant in the United States.

According to a study published by One, when children are infected, they release fewer virus particles into the air, making them less likely to spread the virus. German research team found†
