Pfizer is one of 10 companies developing COVID vaccine in phase 3 trial

However, it said it still expects booster shots to be necessary ahead of the winter season as antibody levels are expected to wane.

It and rivals Pfizer and BioNTech have been advocating a third shot to maintain a high level of protection against Covid-19.During a second-quarter earnings call, Moderna CEO Stephane Bancel said that the company would not produce more than the 800 million to 1 billion doses of the vaccine that it has targeted this year.“We are now capacity constrained for 2021, and we are not taking any more orders for 2021 delivery,” he said.Moderna shares fell 3.6 per cent to around US$403.87 (S$545) in pre-market trading after closing at US$419.05 on Wednesday.That compares favourably with data released by rivals Pfizer and BioNTech last week in which they suggested their vaccine's efficacy waned around 6 per cent every two months, declining to around 84 per cent six months after the second shot.

Both the Moderna and Pfizer-BioNTech vaccines are based on messenger RNA (mRNA) technology.

실시간바카라"Our Covid-19 vaccine is showing durable efficacy of 93 per cent through six months, but recognize that the Delta variant is a significant new threat so we must remain vigilant,” Moderna chief executive Bancel said.The comment comes as public health officials across the world debate over whether additional doses are safe, effective and necessary even as they grapple with the fast-spreading Delta variant of the coronavirus.

The pharmaceutical industry is the highlight of the current market state, and it has earned a lot of attention in the last few years.

Some of the few drug stocks, such as Moderna and Pfizer, have earned a special spot during the covid outbreak.

It has made long-term investors invest in the drug stock market.

In the latest coronavirus vaccine latest update, the US-based biotech company Moderna released new data on Monday which conclusively strengthens its case for the covid-19 vaccine.

The study stated that the moderna vaccine is 94% effective, and causes the human immune system to produce potent antibodies that endure for at least three months.Moderna Inc said that it expects between 100 million to 125 million doses of its experimental covid-19 vaccine available globally in the first quarter of 2021, in this latest covid-19 vaccine update USA.

The company added that around 85 million to 100 million of those doses would be available in the United States, while 15 million to 25 million available outside the country.The first-quarter doses are within the 500 million to up to 1 billion doses the company expects to manufacture in 2021, as per the covid-19 vaccine tracker.The vaccine, mRNA-1273, achieved high levels of binding and neutralizing antibodies in its test subjects.

Although these high levels of antibodies produced due to this covid-19 vaccine declined slightly over time, by introducing a booster vaccination the levels could be maintained high, for up to three months in all participants.The COVID-19 vaccine race:The Moderna vaccine built on the company’s previously reported findings, based on its study of about 30,000 volunteers.

In the study where both placebo and active shots were given to volunteers, only 11 of the active volunteers reported cases as opposed to the 185 cases in the placebo team.In other covid-19 vaccine news – Pfizer, which has developed a similar vaccine, reported similar findings.

Both Moderna and Pfizer vaccine showed promise in preventing severe cases.Based on these findings and the analysis of the vaccine’s safety and side-effects, Moderna has submitted an application for emergency use authorization to the food and drug administration(FDA).Pfizer applied for the same for its covid-19 vaccine on November 9.

On Aug, 15, the U.S. Food and Drug Administration amended the emergency use authorizations (EUAs) for both the Pfizer-BioNTech COVID-19 Vaccine and the Moderna COVID-19 Vaccine to allow for the use of an additional dose in certain immunocompromised individuals, specifically, solid organ transplant recipients or those who are diagnosed with conditions that are considered to have an equivalent level of immunocompromise.

The Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices is scheduled to meet Friday to discuss further clinical recommendations regarding immunocompromised individuals.

Today’s action does not apply to people who are not immunocompromised.

“The country has entered yet another wave of the COVID-19 pandemic, and the FDA is especially cognizant that immunocompromised people are particularly at risk for severe disease.

After a thorough review of the available data, the FDA determined that this small, vulnerable group may benefit from a third dose of the Pfizer-BioNTech or Moderna Vaccines,” said Acting FDA Commissioner Janet Woodcock, M.D.

As we’ve previously stated, other individuals who are fully vaccinated are adequately protected and do not need an additional dose of COVID-19 vaccine at this time.

According to investigate published inside the Aug. 18 early-release problem of the USA facilities for disease manipulate and prevention morbidity and mortality weekly document, the effectiveness of MRNA immunization against covid-19-related hospitalization is sustained over 24 weeks.In an evaluation in 21 hospitals in 18 states, Mark W. Tedford, M.D., Ph.D., of the cdccovid-19 response team, and co-workers assessed the period of MRNA vaccine efficacy (Pfizer- BioNTech or Moderna) in opposition to covid-19-related hospitalization among adults aged 18 years and older.TheNuherald
